[2023] Can goldfish live in tap water? (Tap, Distilled, Or Well Water?)

Can goldfish live in tap water

The Water! Like the air that fills your lungs, water helps Goldfish obtain oxygen in their fish tank. If you don’t get good water quality, it can cause goldfish problems. If water has toxic chemicals, it is tough for fish to survive. Can we live if our breaths burn our lungs? It can be a problem if you put goldfish in tap water but don’t treat it before goldfish is deposited in the Goldfish tank water. let’s started for Can goldfish live in tap water..

Untreated vs treated tap water

Can a person get a goldfish, fill the aquarium with untreated tap water, then take the pet to the Goldfish tank. That’s not a good decision; unless you have conditioned the water with a regular aquarium water conditioner before introducing the fish. Even where tap water is thought safe for drinking, it is unsuitable for aquatic species, such as goldfish and other fish. Can goldfish thrive in tap water? Goldfish cannot survive in untreated tap water. Untreated tap water is usually high in chlorine, killing a fish or destroying the bacteria in your filtering system.

The best water for your aquarium

A house aquarium provides hours of pleasure and relaxation — and health advantages. Studies show that spending 10 minutes with fish on the fish tank leads to reduced heart rate and blood pressure. To create a healthy environment in the fish habitat, you must keep the water in the best quality. This guide will help you determine what water a Goldfish tank needs.

What is best water for goldfish tanks/bowls (Tap, Distilled or Well Water)?

It is important to ensure that your goldfish is in the optimum water possible – preferably a shady place! The fish of the tank or pond need just the same fresh clean water that those living in rivers. How damaging is distilled water for goldfish? Please follow this guide for finding the most perfect water conditions for Goldfish.

What kind of water do goldfish need?

Maintaining goldfish is very easy. Should I add salt to the water? Is the available water distilled, from the tap or well water? Goldfish need clean water and standard parameters.

Have you forgotten the water conditioner? Make untreated tap water safe for goldfish

Even if your goldfish has acted strangely in the water, you can permanently save it in time. Get ready, immediately treat the aquarium using water conditioners based on the directions on the back of the package. If chlorine is present within your water supply, your aquarium may have already destroyed; many beneficial bacterial that have been filtrating your water. Bring a goldfish to a cycled aquarium and make sure the existing tank completes the nitrogen cycle again. Initially, this may cause gill damage. Add air stone to improve airflow.


How do fish survive in tap water? Goldfish shouldn’t get untreated tap water. When the fish has been exposed to chlorinated water, they begin to develop skin irritations. Even the most minuscule amounts can cause severe damage to the fish. It shows visible signs of distress when coming into contact with bad water. These fish should probably not be allowed to live beyond the next day on tap water. It won’t breathe right and may perish within time.

Can I use bottled water for my goldfish?

If you are using water from natural sources, there’s nothing wrong if you are using bottled water. Generally, bottled water is cared for maximum removal of pollutants and contaminants. Water mustn’t contain chlorine or any chemicals. Springwater is rich in the minerals needed for goldfish survival. Similarly, if you use huge tanks, buying this kind of water can become quite expensive. Measure pH levels in the bottles before use to ensure that they’re in an acceptable range.

How can you make tap water safe for fish?

Depending of the method, there are various ways of preventing contamination from entering through the tapwater of your property. Adding a water conditioner can be done quickly and easily and is most used by aquarium keepers. There are conditioners of different types and brands for all tastes and pockets.

Can goldfish live in distilled water?

Sometimes people ask about using distilled water in tanks to keep goldfish. Distilled water alone can be detrimental because it removes all minerals from it. The addition of minerals to your tank water should help your goldfish become able to survive. If you plan to use distilled water, it can work if you add the right minerals for your fish.

Can goldfish live in tap water

What’s the best water for goldfish?

As long as you condition your tap water before adding it to the tank, everything is going to work. I would strongly recommend looking for an excellent water conditioner; It’s easier and cheaper to obtain and is very efficient. The aquarium must be big enough when you keep goldfish in your tanks. They should have a capacity of 50 gallons or more. Please read more articles on this site!

Reverse Osmosis

Some people choose to utilize the reverse osmosis filter for removing water minerals. These work by pumping water through a permeable membrane, removing small particles and debris such as chlorine and heavier metals from the tap water. It is fascinating, but it removes everything from the water, like all the essential minerals that feed the animals and plants. However, it is possible that you can overcome it with remineralizing buffers.

Can goldfish live in well water?

In some regions, well water can make the best use of your tank. Sometimes, it is not recommended to use this kind of water because it is unknown how many bacteria or metals are contained. The risks exist. Even when you’ve heard of successful water use, knowing that a well is completely different from another is essential. Test your well water before using it.

Leave water out

Another option that some people select is to keep water in an open container. It takes an average of 24 hours for some compounds (such as chlorine) to volatilize from the water. However, chloramine and chlorate cannot be removed in this way. So basically, you’ll have to add some conditioner to your tap water.

Can goldfish live in tap water without filter?

Goldfish could easily be found in any water tank with no filter. In this case, you will need to do water changes very regularly to remove any dirt or debris and maintain the proper water quality. If you don’t install filters, it will likely cause a lot of health damage; always have a filter sponge in your tank. Never keep a tank without aquarium filter.

Can you use Bottled Water for your Goldfish?

Bottle water is available for the Goldfish tanks, but you should treat that water the same way tap water is treated. You can treat this water with a water conditioner before using it because it can contain some toxic chemicals to Goldfish.

What’s the best water conditioner for goldfish?

Most commercial water conditioning products will work perfectly for your tank.

Keep tap water safe for goldfish: The Healthy Water Treatment Program

Goldfish can feel the presence of unwanted compounds in your tap water immediately when you add it to the tank. Sometimes they may even try jumping straight out of water. If you use water with harmful chemicals and heavy metal content (and leave it untreated), your Goldfish may never survive. Never risk it. If you don’t know if the tap water is safe to fish, you must eliminate chlorine disinfectants or heavy metals in the water.

Can I use well water for goldfish?

Occasionally a person with good water in their home area might use mineral water to fill a fish tank with Goldfish. Well water also could contain heavy metals and other toxins that kill fish in minimal quantities. Well water also may have several fertilizers. When we use healthy water, it must be clean and fresh, without chemicals or chlorine.

How do you make tap water safe for Goldfish?

A serious problem when using tap water for fish tanks is that the water in most places will contain chloramine. Chlorine is the least difficult of the two compounds because it will soon evaporate into the air. Often, however, chloramines are used for drinking water purification. Chloramine is not volatile. It may be a good idea to purchase chlorine removal products.

How to condition water for your aquarium?

What water you use in an aquarium will require conditions so your fish can flourish there. When you maintain good aquarium water quality, it must contain the proper balance for the fish and the good bacteria to live happy and healthy. To prepare the water for the tank, you must test the water you use. If you want an improved pH level for water conditioning, you can use Baking Soda to increase the bicarbonate content.

Aquarium water sources

When you provide water to an aquarium, you have many options. In freshwater tanks, water can be accessed from different water sources. The saltwater tank needs a salt mixture. However, it’s essential that whatever you use your drinking water with requires a bit of treatment for your fish. Always test your water before putting fish in your tanks.

Municipal tap water

How can I quickly get the fish into the water by turning on a faucet? When drinking water from the municipal network, the water underwent physical and chemical treatments to clean and remove most bacteria. The water quality is still variable based on the area. Occasionally water is filled with minerals like iron, fluor, and magnesium. Some tap water contains ammonium and organic matter, irritating delicate aquatic animals. One of the problems with using public water for fish tanks is the high content of chlorine which is frequently used in public drinking water systems.


Using rainwater in aquariums is an easy way to conserve money. Rainwater has a relatively low minerals content, which makes its pH fluctuate. Also, you must test and treat rain waters to ensure that they do not cause damage to your fish. Rains are also susceptible to contaminators in the air. Raindrops can absorb pollutants as they drop. Water that falls on a rooftop before collection may also collect toxic things from the shingles.

How to Soften Water Aquarium? (Safe & Effective Methods)

How to Soften Water Aquarium

An aquarium can contain fish and invertebrates that need soft water to survive. Unfortunately, some areas receive hard water from the supply network; this water contains minerals potentially threatening soft water animals and plants. If an aquarium needs softer water to make it habitable, follow these steps to get better water performance – and see our best recommendations for soften aquarium water. so let’s get started on How to Soften Water Aquarium..

What is water hardness?

The higher the percentage of free minerals in the aquarium water, the harder it is. Amazonian waters can reach as little as 10 mg of salts per kilogram compared to African lakes with 300 or 600 mg. To keep our animals living well, we need to provide the ideal and specific water conditions for our fauna. Soft water fish can usually survive in harder waters. However, the possibility of breeding or spawning these fish is virtually impossible in hard water.

How to soften aquarium water

For some aquarists, the hardness of tap water can harm the aquarium’s inhabitants. The easiest ways to reduce aquarium resistance include using simple methods like Reverse Osmosis, Rainwater, Peat moss, Driftwood, and Water Softener Pillows are commonly used to soften water tanks. Each technique has disadvantages and features, meaning that not all of them can serve a specific use. Various methods for softening the water below need further practical study by the aquarist.

How to Soften Water Aquarium

What you need to know to soften aquarium water

Hardness refers to the levels of calcium or magnesium found in water. Carbonate Hardness (KH) is the property that indicates the concentration of metal ions dissolved in water. Several fish species thrive in soft water. However, certain fish species do better in hard water. Remember that most fish species are bred in captivity and do not enter the wild, so they are more adapted to our tap water.

Softener Pillows

Water softeners pillows help remove salts such as calcium, magnesium, and contaminants such as heavy metals and lower pH. Hardness reduction occurs relatively quickly, with effects seen within 24 to 48 hours. It works by exchanging magnesium and calcium ions for other ions, usually potassium and sodium.

Distilled Water and Demineralized Water

Distilled water has a relatively low mineral content – close to 0. Distilled water can be mixed with tap water to reach the desired hardness level. Distilled water can be purchased for relatively low prices.

Reverse Osmosis Water

Reverse osmosis is when minerals are removed from water through semi-permeable membranes. A reverse osmosis system pays off for large or saltwater aquariums despite its high cost.

Catappa leaves

The leaves of the Terminalia catappa plant – also known as Indian almonds – are also used to release humic acids and tannins that will soften aquarium water.

How can I tell if my aquarium water is hard or soft?

It is challenging to differentiate soft water from normal and hard water; the method used in aquarium hobby involves using proper tests for aquariums. If you contact your city’s water supply authority, they can provide you with information about the hardness of available water. Online maps also offer clues as to whether the water you encounter is hard or soft.

Carbonate Hardness (KH) & (PH)

Carbonates Hardness (KH) measure of carbonates and bicarbonates. The presence of carbonated compounds may affect water buffers. The higher the KHs, the lesser the probability of pH fluctuation. For comparison, a low KH level increases the chance of harmful fluctuation parameters waves at the fish tank. The two are closely tied — modifications on KH could negatively affect PH.

General Hardness (GH)

Calcium- magnesium is incorporated; the dissolved mineral content increases. Some fish species, especially some tropical fish, will experience hardiness problems in waters in an exceedingly low percentage. This exact figure may differ for some species.

Tell me the best GH (general hardness) for an aquarium?

This requirement differs for some specific species and types of tanks. Research beforehand which animals you want to keep, then find the perfect GH to suit your aquatic animals.

How is water hardness measured?

The good news for many chemists is that the technology also helps improve water hardness. Hardness can be measured based on the electrical characteristics of the water and measured from a probe in the aquarium water or colorimetric tests. These devices provide a direct hardness value expressed in degrees of hardness for any unit (DEH). At the standard DGH level, CaCO levels are 10 mL to 1 Mpl, equivalent to 17.85 ppm.

How To Test Water Hardness In Aquarium Water

The easiest way to test water hardness is to use an aquarium test kit. According to your test results, your water can be one of two types.

How to test Alakalinity or Carbonate Hardness (KH) in the aquarium water?

Alkalinity or carbonate hardness is measured using carbonate tests. Specifically, acidity in aquaculture can be attributed to fluctuating water pH. Higher KH readings indicate more water resilience to pH changes, thus lessening sudden changes. On the other hand, lower KH means it is susceptible to more constant pH fluctuations. Use proper tests for aquariums to correctly gauge your KH and pH to keep the water parameters stable.

How to test General Hardness (GH) in the aquarium water?

Use water hardness tests in your aquarium water. The resulting aqueous solution is tested based on calcium and magnesium concentrations. Lower levels of GH (0 to 6 d) indicate soft water, and higher levels (greater than 9 to 12) indicate hard water.

How does water become hard?

Waters stream become harder (GH) and alkaline when they pass through rocky surfaces such as limestones. Even limestone deposits on surfaces could cause mineral concentrations to rise in water. For some aquariums, it’s challenging to get “aside with the situation.” Hence they have many problems getting this information. They will be a significant threat to fish, in particular softwater fish. Water General Hardness alkalinized by water is essential for detecting the level of hardness in that water. Use these guidelines to know the water hardness content inside your water.

What causes aquarium water hardness problems?

Every aquarist uses water in their aquarium, but there is no universal mineral composition for natural water. Oyster shell material can intentionally increase the water’s hardness in the system. Another reason for increased water hardness could be a chemical mixture or various limestone substrate-based compounds. The water hardness depends on the geology available at the water source, not the local water source in general. There are geographic differences between countries and regions, and there are no specific values for this.

How can I soften aquarium water naturally and chemically?

When you decide to soften your aquarium water, use the suggestions contained here. Depending on the state of the source water, it may be necessary to change its parameters. But we do our best thinking step by step. I recommend treating the aquarium water in a separate container for best results and less risk of making mistakes.

Tell me the best way to soften aquarium water?

Fish are unlikely to allow any flexibility about parameters such as water, salinity, or nitrate content. Fish may be suffering from distress or about to die when levels are below the comfort level for the species. The hardness of the water in ponds is an attribute for which many fish have become well-trained adaptors; captive-bred aquatic creatures can withstand closer hardness with water from our supply networks.

How to Soften Aquarium Water | Water hardness Softening Methods

To soften aquarium water, the process usually occurs slowly at a gradual rate. It is guaranteed that the fish will not have severe consequences from a clash of parameters, as it changes the chemistry of the water very quickly. Softening the water is more complex than ultimately raising the water’s hardness. Weekly tests will show the difference between KH, GH, or pH levels. Soften the tank water slowly.

Soften aquarium water hardness inside your tank

There are small mesh bags with different dimensions that meet the needs of your container size. Use the mesh bag to insert the peat moss tightly. Kh, GH, or pH should be tested regularly every 12 hours. Remove the moss bags when you reach the desired water parameters.

How to Soften Water Aquarium

Peat Moss (Sphagnum)

Peat mosses are decaying, dried mosses that can be classified into several species with an inherent ability to soften and reduce water pH. Peat mosses for aquariums are available at pet markets. Peat mosses include tannins that make the water brown; if you don’t want the water in your aquarium to turn that color, boil the peat for approximately an hour until the peat loses its brown color. Another solution is to dip the peat in a bucket to remove some dye. Once the process is completed, it is possible, with three techniques, to use the method efficiently.

Peat Moss As A Substrate Layer

Using peat as a substrate to soften water hardness is not a bad idea. This peat moss is fluffy and light, allowing it to move with the movement of water, avoiding anaerobic layers. The addition of other compounds such as gravel and sand to the substrate provides a different granulometry, benefiting the passage of water and promoting bacterial growth. Peat moss may color the water column; for this not to happen, the peat must be cleaned and preferably boiled before going to the tank. However, there may be differences in their method of use, as in the case of raising annual killifish; this is its most popular use. The peat pile releases substances that neutralize the minerals and soften the water.

Peat moss filters

Peat moss inhibits water hardness by binding calcium and magnesium. It is also called chelation, which softens aquarium water through demineralization. Peat produces tannin and humic acids. Oxidative ions have a decrease in KH: the acid neutralizes the carbonates in the water. A mixture of tap water from our home with peat can help with this problem of high water hardness. You can place a layer of peat directly inside a filter system to soften aquarium water hardness.

Peat Moss Inside Aquarium Filter

Place a bag full of peat in the tray or separate portion for media in your filters. The operation of the process in this way of the bags follows the same precept mentioned above. In filters, you can also use small grainy peat moss grains that are pelletized, which helps the peat moss enter and stay in the mesh bags; this will help prevent the moss from blocking the passage of water.

Using Rainwater In The Aquarium

Rainwater offers you something that unfortunately cannot be found everywhere. If you live in any weatherproof location – rainwater is acceptable for this aquarium. The storage tanks will hold plenty of moisture throughout the wet seasons. It should contain fresh, sterile foods and other materials to absorb rainfall to avoid contamination. In this case, your water supply should consist of water and rain in the same proportion that ensures appropriate pH and DH concentrations. The water must be kept under the air in clean containers with lids.


Usually, the simple way to soften aquarium water with a simple process of using water collected from rain can be a success for any hobbyist. In all likelihood, you could use accumulated rain as an opportunity to monitor GH and KH levels. To adjust its hardness to optimal levels, you can mix rainwater with tap water. Rainwater must be collected following some safety procedures such as not collecting in areas close to industries and other factories; it is also not ideal for collecting rain in high pollution conditions, such as acid and toxic rain.

Using Distilled Water

If you have distilled water available, be aware that you can use it as aquarium water. Water distillation consists of pure water extracted as a result. Hot water to create liquid-vapor causes pure water vapor to condense to produce distilled water. The development of the distillation is pure water, which means that all dissolved minerals in the water have been removed during the distillation. The best way to use distilled water is to use it alongside tap water before adding it to tanks.


Driftwood reduces hardness in aquarium waters based on natural techniques. With a high tannin content, Malaysian floating wood provides good softness to the water. The tannins are released, in response, the water’s hardness decreases. Many people prefer tannin-producing leaves (such as Indian almond leaves) to reduce water hardness.

Water Softener Pillow

Softeners have a hardness reduction mechanism containing oxygen to replace calcium and magnesium and insoluble heavy metal ions. They must not adversely affect your fish or plants. Water softening equipment is the perfect solution for small tanks and often needs to be removed because of its sudden effectiveness. Please follow the product usage information, as the usage method differs from product to product. Softeners reduce salt deposits and carbonate hardness in the aquarium water in a short time.

Reverse Osmosis (RO/DI)

If the hardness problem persists, you might want to use an RO or DI unit. A RO/DI system passes the water through a membrane filter to remove dissolved minerals, metals, and such. RO water has neutral to zero parameters. Also, using some raw water and adding minerals can make your RO water very useful in different systems. Using RO, adjusting the carbonate hardness and pH in your aquarium will become much more manageable.

Will softening the aquarium water harm my fish?

Hard water can damage your fish pets, but lack of minerals can cause serious illnesses. Fish have different water requirements concerning the species and their habitat, so we must continually adjust the hardness to the perfect standard for their fauna to survive. If you have very hard water, reducing its hardness suddenly can cause severe damage to your fish. Lower the parameter slowly, with the help of tests and water changes; this way, your fish will be free from possible physiological shocks.

In conclusion

These aquarium water hardness adjustment options are helpful for tropical fish that need little or no amount of dissolved salts in the water. There are specific kits for measuring GH, Kh, and pH in aquariums that can also allow you to determine the status of parameters and assist in correcting the characteristics of the water in your tank. Use a buffer when using acidifying products to make water soft in tanks; in this way, the pH remains constant due to the buffering effect, preventing it from rapidly changing. Rapid acidification of ph or drop in hardness can harm animals and plants.


There are several ways to soften your aquarium water to get the optimal results you want. Reverse osmosis systems are ideal for large tanks, saltwater aquaria, or unique soft water animal tanks and are widely used by fish breeders. Remember that monitoring GH and KH levels should become a routine to check and correct the hardness of the water in your aquarium. Incorporate progressive changes in aquarium water hardness; always carry out corrections piecemeal, avoiding sudden parameter shocks.

How to Raise KH in Aquarium? Complete Guide

How to Raise KH in Aquarium

In this article we explain KH and its importance to the aquarium and we show how to Raise KH in Aquarium water. We also address GH and pH as all these water measurements are interrelated.

KH is also known as Carbonate Hardness. Its the parameter which can change the most on a daily basis in an aquarium or pond. Carbonate hardness blocks natural acidity and stabilizes pH levels in fish ponds. KH increases and stabilizes the pH.

The greater the KH, the more resistant the aquarium water will be to pH changes. Having a higher KH should prevent large pH swings in your tank over time.

If your tank’s KH level is below 4.5 dKH, you should pay special attention to your tank’s pH. It is advisable to test weekly, until you understand how stable the pH is.

Understanding pH, KH and GH

Aquarium enthusiasts all understand the importance of having stable water parameter to ensure a healthy ecosystem for their fish. Correct water chemistry will ensure the health of your fish and by keeping the water within parameters mortality rates of fish will be reduced. pH, GH, and KH are water parameter measurements you will become familiar with.


pH stands for Power of Hydrogen. pH gauges the Hydrogen Ions in your aquarium. It shows acidity and alkalinity. pH is measured on a scale of 0-14. High pH means alkaline, low pH means acidic and a reading of 7 is neutral.

Different fish have different tolerances of pH. Most aquarium fish thrive in a neutral pH water of somewhere between 6.5 and 8.

Small fluctuations in pH will cause no harm to your fish, however, a big spike in pH levels is harmful.


The KH (carbonate hardness) measures the carbonate and bicarbonate ions in your aquarium. KH is  the ability of water to keep the pH stable (buffering capacity). KH neutralizes the acids present in the aquarium water. This prevents the pH from crashing. pH crashes can harm and potentially kill your fish.

An inadequate buffering capacity is indicated by A low KH level and results in fast pH swings. Whilst, if the KH is high, your aquarium water has a higher buffering capacity, making it harder to change the pH level.

The ideal KH level for a freshwater aquarium is somewhere between 4 – 8 dKH or 70-140 ppm.


GH refers to the general hardness of the water.  It is a reading telling you the amount of calcium and magnesium ions present in the water. GH measures the ‘hardness’ or ‘softness’ of your water. It is recommended to have a GH level between 4 – 8 dGH. A low GH can affect the health of plants and fish.

How are pH, KH and GH related?

Although pH, KH, and GH are measurements of specific ions, they are interrelated and all play a part in balancing water chemistry. When minerals are added to the aquarium, they release many ions that affect water parameters.

Limestone, for example, contains a higher level of calcium carbonate. By having both calcium and carbonate ions, you raise both GH and KH when added. Salt mixes specifically created to raise either GH or KH can be purchased.

KH is directly effects pH. It buffers the pH, preventing it from changing rapidly. pH levels tend to decrease in fish aquariums over time. By raising the KH more acids are neutralized, and pH stays higher.

For example, by adding a buffering agent such as crushed coral to a tank with a higher pH level will only raise the KH, not the pH value. Yet, by adding crushed coral to lower pH water will increase both pH and KH values.

If the KH in your aquarium falls, you need to increase the carbonates and bicarbonates in the tank. Commercially prepared alkalinity buffers can be purchased and can be used to raise the KH in your freshwater aquariums. These products make it easy.

Crushed coral combined with aragonite is a perfect alkalinity buffer. The advantage is that it changes KH slowly and steadily.

Why is KH important to your aquarium?

pH Fluctuations

The main benefit of having higher KH levels is its effect on pH. KH inhibits pH levels from becoming to low (extremely acidic). It also stabilizes pH, preventing pH crashes and excessive fluctuations. A rapid change in pH affects many aquarium species. Chemical parameters such as pH are crucial to aquatic life in aquariums and ponds.

KH and marine aquariums

KH is important when it comes to corals in saltwater aquariums.

Corals can survive a broad range of Phosphate levels, however, if the KH is too low for an extended period, all aquarium corals will die.

KH naturally reduces with time due to natural processes and coral growth. When its level is low this can contribute to the pH being low. The ideal KH value for a reef aquarium is between 8 & 12 (3 – 5 meq/l).

A low KH can be corrected by adding Reef Builder or Seachem Reef Carbonate.

KH Influence On Plant Growth In A Freshwater Aquarium

With aquarium plants, the preference for alkalinity is not always discussed.

KH has no real benefit to plants (neither does it harm plants). However, KH affects pH, and a high or low pH may not be suitable for certain species of aquarium plants.

Carbonate hardness stabilizes water quality, so its influence is natural. The number of aquarium plants that survive in very soft water is relatively low.

High pH levels can impede the uptake of nutrients by plants.

Soft water plants prefer higher temperatures and lower KH. Hard water plants with moderate pH preferences can still survive at low KH levels.

How to raise KH in aquarium water

1. Potassium Bi-Carbonate

Understanding how to raise KH in aquarium water is quite simple. In a planted aquarium this is best done by adding KH2CO3 or K2CO3 (Potassium bi-carbonate/carbonate). A double benefit is that the potassium acts as fertilizer for plants as well.

  • 3.5 gms of KHCO3 in 100 litres (26 gals) of water raises KH by 1 dKH.
  • 2.5 gms of K2CO3 in 100 litres (26 gals) of water raises KH by 1 dKH.

2. Limestone or coral chips

Another simple method to raise the KH levels is by putting pieces of limestone into the filter, the sump or into the tank. Coral chips in a bag work well, although we recommend limestone over coral chips as larger stone is easier to handle and remove.

Tanks with limestone naturally have higher KH levels. The quality of the limestone/coral chips will determine how quickly the KH will rise. Usually from 0 to 10 within a week.

3. Dolomite Rock

Dolomite rock (CaMgCo3) can also slowly raise and maintain a steady KH in your tank. It gradually releases magnesium, calcium, and carbonate in your aquarium. These elements cause the KH to rise. An advantage of dolomite rock is its appearance that looks great as a substrate. This option is ideal for aquariums that require a constant high KH.

4. Aragonite

Aragonite is another natural carbonate mineral that is aquarium fish safe. This mineral provides a constant source of KH enhancer. Smaller tanks require smaller pieces of aragonite and larger tanks, more. Place in the tank or in the sump tank.

5. Soda Ash

With saltwater tanks use Soda ash. Soda ash is not suitable for freshwater as it releases excess sodium into the water in mineral form. Add small quantities over a period as it will instantly raise the KH and pH in an aquarium. Test and monitor the water with a KH test kit  to ensure the level is not too excessive.

6. Baking Soda

To increase the KH without raising the GH, you can add sodium bicarbonate (NaHCO3), commonly known as baking soda. By adding one teaspoon per 50 liters (13 gallons) raises the KH by about 4 dH.

7. Water changes

Conducting water changes by removing a third of the tank’s water and replacing with a water source high in KH will help gradually increase KH. Many tap water sources are quite high in KH. Always test the water so that you know what you are adding.

How to Raise KH in Aquarium

What is the ideal KH level for aquariums?

KH is measured based on dKH (degree KH) and ppm (parts/Million, 1dKH equals 17.9 ppm of calcium carbonate per liter). Each fish species has its specific KH value requirement.

  • Brackish water: 10 – 18 dKH
  • Planted aquarium: 3 – 8 dKH
  • Shrimp aquarium: 2 – 5 dKH
  • Cichlid aquarium: 10 – 18 dKH
  • Pond: 4 – 8 dKH
  • Discus aquarium: 3 – 8 dKH
  • Tropical fish aquarium: 4 – 8 dKH
  • Marine reef aquarium: 8 – 12 dKH


How to decrease KH?

There are several ways to decrease KH levels in the aquarium. Increase the tannin in the water by adding Indian Almond leaves (particularly when housing Betta fish), or by using peat. As the leaves or peat break down in the water they gradually begin to use up the KH, this lowering it.

Another method is to mix distilled water with the tank or tap water. Distilled water contains no minerals, therefore no KH. By blending it with the tank water KH levels are reduced.

Having an abundance of aquarium plants will help reduce KH when used with a buffer. These buffers are typically utilized by the live plants to reduce the excessive CO2 from aquarium water. Plants use the buffer to convert KH to CO2.

How To Test And Measure KH In An Aquarium?

Carbonate hardness can be easily measured using KH-based tests. Ensure you have a quality test kit for your specific aquarium (marine or freshwater). Set up a schedule for water tests, being prepared if water adjustments need to be made.

Test pH and water hardness (GH) at the same time.

The greatest fluctuations in water chemistry usually occur when new water is introduced to the tank after cleaning or during part water changes. It is recommended to test the water you introduce. If the KH is above acceptable levels, use the suggestions above on how to raise KH in aquarium water, to correct them.


How to Raise KH in Aquarium


FAQ – How to raise KH in aquarium water?

Will increasing KH increase my pH?

Yes, they are related. In general, a higher KH will result in a higher pH. The pH will also be more stable (reduced fluctuations).

What causes KH to drop in a freshwater aquarium?

KH can drop as the rate at which acids are being produced in the tank is accelerated. The acids ‘eat’ at the water’s carbonates/bicarbonates.

Having too many fish, or adding too many at once can increase acids. Ammonia build-up due to fish wastes, excess food and organic matter decomposition also increase acids. Once KH levels are too low for pH stability, the aquarium will likely have a pH crash.

What affect do frequent water changes have on KH?

As fish wastes build up in a tank, so does the acid level, thus reducing KH. Periodic partial water changes remove the polluted water, replacing it with new clean water. This will restore the KH level.

If you have a larger tank that has a good biological filter and a sump tank, the need for water changes will be far less. The beneficial bacteria in a ‘cycled’ tank will eliminate the nitrates and ammonia from the water. Smaller tanks will require regular water changes.

Also, the water you add during a water change will often have a higher KH. This will be determined by where the water is sourced from.

What happens when there is too much CO2?

CO2 supplementation can provide vital nutritious energy for the beautiful growth of different aquatic plant species. Adding CO2 to the aquarium lowers carbonate levels, causing acidification in your aquarium. Having a high KH will prevent problems and keep the pH at an acceptable level.

What happens when the aquarium is overcrowded?

Inherently, unstable conditions occur when aquariums are overcrowded. Fish waste will cause acidification causing KH levels to drop, risking a pH crash. A drop will cause your fish to stress and the less hardy species will start to die.

Having enough water in your aquarium is the best method to improve the health and stability of your aquarium. Using a sump tank will increase its volume. In addition, efficient biological filters will allow for higher stocking rates.

How to Raise KH in Aquarium?

How to reduce hardness in aquariums?

The difference between KH and GH.

Carbonate hardness (KH) is measured by measuring the amount of carbonate and bicarbonate in water.

Whilst GH is a measure of dissolved magnesium and calcium ions. This is what people usually mean when they refer too water being “soft” or “hard”. Generally, plants and most tropical fish and shrimp do best in a dH range of 4-8 dH (degree hardness). This is considered somewhat soft.

Tap water can have both high GH and low KH, therefore, not always ideal for your fish.

How to soften water?

In order to reduce the hardness of water use peat moss or drift wood. This process works by binding calcium and magnesium ions. It will also release tannic and gallic acid into the water. These acids attack and degrade bicarbonates in the fish aquarium, thus further reducing the carbonate levels and the waters PH level.

Place the peat inside the aquarium filter to allow for maximum flow through the peat.

Alternatively, clean rain water is considered ‘soft’ and can be mixed with tank water to reduce hardness.

Final Thoughts – How to raise KH in aquarium water?

The secret to keeping aquatic live healthy, stress free with a strong immune system is to ensure they have optimal water. Keeping water parameters balanced and within the best range for the species of life in your tank is important.

Understanding KH, pH and GH, and scheduling in regular water tests, will ensure that you are alerted to any water issues. Knowing this will provide peace of mind and will likely save you from much heart-ache.

Understanding how to raise KH in aquarium water is core to maintaining steady pH and keeping water hardness within parameters.



How to Safely Lower pH in Your Aquarium ( Best Working Methods )

Lower pH in Your Aquarium

When making a new aquarium, we all must try to control, among other factors, the pH before adding fish. Tap water can be slightly alkaline, but it’s usually suitable for many fish you buy at the pet store. Most captive-bred fish are resilient, tolerate a wide range of Lower pH in Aquarium, and tap water is generally suitable for all of them.

What is pH in aquariums?

In chemistry, pH is a scale used to specify the acidity or basicity of a solution. It is scored in dots, ranging from 0 to 10, where 0 is the most acidic and ten the most basic, where each number has its scale plus 10 points. To measure it, we use our aquarium tests, which can be digital or manual. The pH can affect a significant change in the entire ecosystem of the pond. The pH in your aquarium is not a fixed variable; it can fluctuate depending on environmental conditions such as temperature, amount of organic matter, oxygenation, etc.

pH in your home aquarium

Understandably, some people might find it challenging and sometimes frustrating to maintain pH in an aquarium. I keep the parameters correct and stable; in addition to being more beautiful and showy, your fish will also be able to survive longer in your tank. This article shows you everything you need to know to lower and control the pH level in an aquarium. The pH in the aquarium is a critical part of keeping your animals active for aquarium survival and health.

Controlling the pH in home aquariums

There are a few ways to control the pH of aquarium water. Some acids affect the aquarium water instantly, which is not ideal. Never change pH values too quickly as this can harm or kill your fish; the pH should be raised slowly; the longer it takes, the less parameter shock your fish will feel. Make sure you understand the pH of tap water and your pets’ requirements to make adjustments to freshwater before putting it in the pond. Also, check the quality of the aquarium water. This knowledge is essential for your pets’ healthy environment.

Some tips

Test the aquarium pH frequently, whenever you can; that way, you will understand what causes the variations. Add fish and plants capable of handling large pH ranges and different types of water such as Guppies, Bettas, Java Fern, and Anubias. If you prefer to keep fish acidic, you can take steps that will slowly acidify the water, such as adding driftwood or peat moss. Buy a reverse osmosis filter if you have a constant problem with fundamental water.

Lower pH in Your Aquarium

What causes the pH to rise in a freshwater aquarium?

Several factors increase the ph in your aquarium. Ph is formed from minerals found dispersed in water. Tap water with lots of traces of phosphorus and silicates added to a tank and often added carbonates will cause its ph to rise to more alkaline sides. Be careful with the material used as substrate; some sand and rocks can be limestone and release many minerals in your water. Be aware of some commercial brands of substrates that may contain chemical substances that primarily affect water. Other causes include malfunctioning filtration systems and some fish-generated products.

How often should I test pH in an aquarium?

When your fish get sick or die, it’s essential to check your aquarium’s pH levels. This check should be done regularly so you can ensure the pH is kept constant in your tanks. Remember to clean the tank, change the water, and remove the dirt that accumulates at the bottom. Glass cleaner can be found in virtually every pet store. The vital thing is to replace some water and vacuum the wastes from the substrate using a siphon. The makeup water must have the ideal parameters stabilized, correctly treated, and free from chlorine and other substances.

Why is it necessary to lower the pH in an aquarium?

The default pH is ideal for your fish, remembering that seven is neutral. There are many reasons why the pH level of your aquarium water has increased, and you may need to lower it. The most common reasons for this are mineral residues deposited in your water. It is essential to check whether phosphates in tap water tend to carbonate when added to your aquarium. One of the causes of lowered pH levels is usually the failure of the filtration system. If the filter fails, you may have to deal with accumulated ammonia that will likely increase your tank’s pH.

When is it necessary to lower the pH in an aquarium?

Many fish and plants survive in their places of origin under narrow and stable water quality parameter conditions and parameters. If you keep Tetras, Discus, Angelfish, Rasbora, and other animals from the tropical equatorial region like South America or Asia, most will thrive at a lower pH (acidic). While some captive-grown aquarium fish aren’t as picky, you get better color and breeding behavior with the proper pH balance. As tap water tends to have dissolved minerals, it’s easier to keep tanks slightly alkaline, but turning it down and controlling it can turn out to be easy.

The proper pH of freshwater aquarium

Some fish do well with a minimum of 5.5, while others are much more comfortable with a little more alkalinity. It is not a static factor in most aquariums and can constantly change, which is not ideal. Sometimes you will need to increase or decrease concentrations. As most water faucets are generally alkaline, it is always worth checking and seeing what is recommended for your fish and plants. If you had a lot of species, like in a community tank, your goal should be to get your tank around neutral, i.e., 7.0. African cichlids and species such as goldfish are resistant and require a higher pH, not fully adapting to acidic pHs.

Lower pH in Your Aquarium

How do I lower the pH in my aquarium?

If you find your pH above the recommended ideal level, then we give you the best tips on how you can safely re-regulate it. This should be done by slowly reducing the PH to the optimal level.

Reverse Osmosis

With the use of selective semi-permeable filters, all unwanted particles are removed from the water using RO. An RO water filter can filter, using membranes, by reducing only heavy ions that modify the chemistry of the water. Even though you may find this method too expensive, reverse osmosis is considered the most effective way to lower the pH in a fish tank with an accuracy that other techniques cannot achieve. Using this method can ensure that the pH levels in storage tanks are continuously at the perfect concentration. Note that the filter itself is extensive, so they are only suitable for larger tanks.

Add driftwood to the aquarium.

Driftwood chunks can help to lower the pH through their production of large amounts of tannin and humic acids. Boiling the wood before adding it to the setup will destroy any harmful fungus or algae that might affect the tank. Although driftwood does not release anything toxic or pollute the water, it is always important to sanitize it properly. This can reduce the color of tea that it may eventually release. If you don’t want the tea color in your water, you can add chemical media to your aquarium, like activated carbon.

Reduce aeration in the tank

The last and most basic way to lower the pH in an aquarium is to reduce the oxygen content. There are certain circumstances where a low oxygen concentration in water results in a low pH. Even after performing all the necessary steps, it is imperative to constantly check the parameters so that nothing gets out of control. Although this method is highly economical, it has to be adapted for the animals in your aquarium; You have to be careful as fish need oxygen to survive, which can cause fish to die if you lower their level to more than necessary. This is a way to lower your tank’s pH level.

Add almond leaves/Catappa

Almond leaves also have medicinal properties, tannins, and acids. This can cure some conditions and even inhibit certain types of fish diseases. They will give your aquarium a natural look. Be sure to wash the leaves first and then add them to the tank as, like driftwood, they can change the color of the water. The color given off by leaves and peat is the same as that of driftwood, but it may appear less dark in the case of leaves.

Perform a periodic partial water change

Even in sizeable 55-gallon fish tanks, it is necessary to change parts of the water regularly; this way, the water in the aquarium will always have a stable pH and get rid of pollutants and toxins that filtration cannot remove. During any cleaning, in addition to the water change, you should also clean the tank walls and decorations and siphon the substrate to remove debris, algae, and unwanted dirt in the tank.

Add Peat Moss

One of the most common and well-known natural ways to lower water pH in a tropical fish aquarium is by adding peat, which has great potential to supply acids and tannins. Peat makes the water dark, with a yellow tint. To determine the correct amount to use, perform regular pH tests.

Other ways of lowering pH in an aquarium

Here are some known and practical techniques to lower the pH safely; if done correctly, they should give good results.

Add Carbon-Dioxide

Carbon dioxide causes a drop in pH when injected into the aquarium water, which is quite simple. You can also get good results if you add organic matter such as soybean, cottonseed, or crushed cotton; this must be done by performing successive tests and with extreme caution. This is because organic matter creates carbon dioxide in water. It is important to remember that carbon dioxide lowering the pH is a very safe technique because it minimizes the pH slowly. You can pump carbon dioxide artificially to get the same result, but be careful not to do something to the tank as well as the fish, and be sure to monitor your pH changes closely.

How do I lower pH in an aquarium with vinegar?

Follow our complete guide to lowering the pH in water with vinegar. The decrease in pH by vinegar depends on the pH and hardness of the water to be modified. The amount of vinegar needed depends on other factors such as impurities in your aquarium (heavy metals), toxins, water hardness, and carbonates. Don’t add all the vinegar to your tanks at once because it lowers the pH instantly, and this causes problems for the fish and your system as a whole. Lowering the pH levels in a tank using vinegar is a simple solution, but other organic methods that allow similar results are safer.

Can vinegar be used to lower pH in a freshwater aquarium?

It will certainly reduce the pH of your freshwater aquariums. Use white vinegar made with commercial distillation if white vinegar has a percentage of 2.55 to 5% of acetic acid.

Is vinegar safe to use to change the pH in a freshwater aquarium?

It’s safe to use vinegar for changing pH at freshwater aquariums. You must learn vinegar affects water. Check the pH level of your tank before try lowering its values.

How much vinegar to lower Ph in aquarium?

To lower pH in the aquarium, apply 100 ml of vinegar per gallon of water. This measurement system has been shown to reduce the pH of the tank.

How do I keep my aquarium ph low and stable?

After lowering the ph in your aquarium, you will need to stabilize that ph. Here are some measures to help keep the ph low and stable.

Clean and maintain your fish tank.

The accumulation of nitrogen compounds in the water can be toxic to fish due to the pH of the pond. Consequently, waste nitrates and phosphates can also cause more alkaline pH concerns. Clean your aquarium weekly, perform a partial water change, and clean and siphon dirt and food debris. Don’t forget to stabilize the pH of the new water with the aquarium parameters. Use your mains water; if it is too hard and alkaline, you can adjust it by mixing it with water from an RO filter. You can ask your regional water supplier for a water content analyzer. Remember to vacuum the substrate as it is essential for good system hygiene.

Check your filters regularly and keep them clean.

If not cleaned for long periods, the filter will fail. Thoroughly clean each component and wash them under running water. Periodically replace the sponge cartridge and carbon filters. Your filters must never be dirty or clogged with particles, and any elements not included in the filters must be removed. Cleaning your aquarium water filter depends on the type of filter and the amount of dirt, relying solely on your system as a whole. You should check all the necessary parts to ensure your filters fail, such as filter inputs and outputs.

One final tip on lowering the pH

What couldn’t be emphasized enough is: don’t significantly lower the pH all at once. It would be best if you were particularly careful when making parameter adjustments in a small aquarium, as changing the pH level of the water doesn’t require a lot of acidifiers. Half a cap full of commercial acidifier is enough to spoil a 5-gallon tank. Fish and plants vary dramatically in how well they tolerate pH adjustments, but always be on the cautious side. If using chemical media, adjust 10-20% of the water volume daily until the pH is where you want it. Many natural pH control methods can cause a slow change over time when done correctly, so they are safer.


There are several ways to achieve a single goal; some are easier and provide better pH control results than others. However, it is essential to maintain the ideal pH in your aquariums. You can choose any medium described above according to your requirements or potential capability. It doesn’t matter which method you choose with more natural alternatives like Catappa leaves or using a less realistic option like using vinegar – whatever your preferences, you should go for it to find the right solutions.

Water Temperature For Guppies: (What Is Ideal?)

guppy temperature

Guppies are tropical fish that live in warm waters in nature. In a home aquarium, Guppies flower more efficiently when the room temperature is controlled. In this article, I cover the water temperature requirements for Guppy fish, whether they need a heater or not. Let’s start Detailed guide about Guppy Temperature.

Water Temperature Range For Guppies

Guppies are incredibly cute and hardy aquarium fish, but they need certain things to survive like all animals. The main thing to take into account is the water temperature. Let’s look at fish as a whole and cover the necessary basic facts. The proper water temperature range for Guppies should be between 74 and 82 F. We’ll discuss everything you need to know about water temperature for guppies and other vital issues. We will also discuss how to heat water to the right temperature and solve possible problems.

Do guppies need a heater?

Guppy (Poecilia reticulata) is a warm water fish. During breeding, guppies prefer cooler temperatures around 74 F. As with all aquatic animals, your aquarium must have a constant temperature. Thus, the use of a heater is necessary. The heater controls the temperature in the aquarium. There is always a problem with monitoring or adjusting the water temperature manually. Your guppies will be affected whenever temperatures fluctuate. Fluctuating temperatures cause a drop in the fish’s immune system, making them more prone to disease. In the case of Guppies, some illnesses can be challenging to treat, so it’s best to avoid them.

About the Guppy Fish

Guppy is generally considered tropical fish as they live in places like Venezuela and Trinidad. The male is a very colorful fish. These fish do very well in a 5 to 10-gallon community tank. Guppies are easily fed; they will eat anything they put in their mouth. Guppies do well in waters with medium hardness and relatively neutral pH around 7.0. A good filtration system and some water changes are essential to keep these guys happy and healthy, and yes, they need a heater.

Can you keep guppies in the outside pond?

You can keep your guppies in an outdoor lake with temperatures between 60 and 65°F. A heating unit is another solution you can have to keep your tank water warm. Using an external tank heater is not easy or economical.

What type of heaters can I use to heat my tank?

When it comes to heaters, a tank can have four basic types. Submersible heaters have the best features for a starting point. This includes hanging submersible heater, subsurface heater, and filter heater. Before buying heaters, the hobbyist must understand the pros and cons. The best heater is reasonably cheap and easy to install. The size of your guppy tank determines the force of your heater; use between 2.5 and 5 watts per gallon of actual water volume in the aquarium.

guppy temperature

Submersible heater

Submersible heaters are placed under the water lines. Vertical and horizontal placements are considered the best as they allow the thermostat to determine the correct temperature; suction cups are used to secure the heater to your aquarium. Glass submersibles can be fragile and require more careful handling unlike plastic submersible heaters. They can be placed vertically, horizontally, and at any angle.

Do I need a spare aquarium heater?

Your Guppy doesn’t stand a chance in frozen water, so the fish must warm it up to survive. Spare heaters will make it easier to replace heating components if the equipment fails; it is advisable to have an extra one.

Substrate heater

A substrate heater is best suited for heating your tank if it contains live plants as it keeps the substrate warm. Substrate heaters have a resistor attached under the substrate that keeps the water warm and stable. Unlike the submersible, the heat from the substrate heater increases evenly while reducing the visual clutter of the display. If you need to change this type of heater, the tank must be disassembled; this discourages many from using it.

Filter heater

Filter heaters are suitable for large aquarium aquariums. Filter heaters are unique because they’re invisible.

Tell me the lowest water temperature that guppies can tolerate?

The ideal water temperature for guppies is 74°F to 82°F. They can survive if the temperature drops to 60°F. Guppies are tropical fish that bloom at warmer temperatures. A sudden change in water temperature translates to an unhealthy immune system, lethargy, and reproductive problems in fish. When the temperature drops below 60°F, the Guppies may not survive.

Tell me the lifespan of a Guppie?

They can survive in captivity for between 2 and 3 years. The best examples of factors that affect your Guppy’s chances of being healthy are temperature, water quality, and fish care.

Related Questions

The process in which bacteria convert ammonia to nitrite and finally to nitrate is known as the nitrogen cycle. Ammonia and nitrite can be toxic to fish. Guppies are lovely and easy to care for fish. They don’t require large spaces, so you can order a small aquarium to start with. You can breed animals for the market because their reproduction rate can be extremely fast.

How do I check my tank?

The most effective part of aquarium management is to carry out constant water changes. The water must be changed periodically every week at the very least. Your goal when cleaning the pond is to regulate the nitrogen cycle, replenish essential nutrients and minerals, and eliminate the dissolved parts of pollutants.

Ideal water temperature for guppies

Fish should be kept in temperature ranges between 70 to 82°F. Lower or higher than this opens up the possibility of a health problem. If the guppies can’t get warm, they’ll get sick.

What happens when the temperature is outside the range?

You need to know what will happen to your guppies if their tank is within or below the recommended temperature range. The first thing to remember is that Guppy is a tropical fish. They are native to warm waters. Otherwise, something else will happen if the tank is not at the correct temperature. The ideal temperature is the guppy temperature aquarium level, so be sure to use a water heater and thermometer to monitor and control the tank’s temperature.

When the temperature is higher

With a water temperature over 82° Fahrenheit, it is declared dangerously hot for the guppies. If temperatures are too high, this can lead to less available oxygen loading in the water and a shorter lifespan for fish.

Shorter life span

Fish will have a lower life expectancy in warmer waters than under ideal water temperatures. The high water temperature causes some problems, such as low oxygen availability.

guppy temperature

When the temperature is lower

Fry can handle temperatures below 70 F better than adults. Many difficulties can be caused by the temperature being below recommended levels. In addition to slowing the growth rate, the low temperature can also leave the fish lethargic at the bottom of the aquarium and swimming slowly.

Slow growth rate

Slow growth rates are one of the things that happen to fish kept in low temperatures. Guppies are stunning and colorful fish as adults. If this growth delay occurs, the temperature must be adjusted significantly if the fingerlings grow faster in other tanks.

Less activity

Fish like guppies are cold-blooded, so they require some external heat source to keep them warm. If they’re cold, they won’t be as active as when things were warmer and more comfortable. This could mean that the fish will die.

Increase in diseases

Therefore, to ensure the healthy growth of the fish, you must always keep the water temperature constant and ideal. Guppies are hardy fish, but they usually get the disease when the water is too hot or cold or fluctuates. Diseases can infect your entire aquarium – causing all your fish to suffer and potentially killing them.

Not enough oxygen problem

The hotter the water, the less oxygen is available and the more likely they are to suffocate. Guppy fish need oxygen to stay healthy and active. Very hot water is usually the cause that most Guppy fish are killed inside beginner aquarium tanks. When the water is too warm, the principal problem is lacking oxygen in the water. You’d like to place a spray bar in the filter output where an air agitation reaction might be on the water surface. To cool down a Guppie tank, the most popular and affordable method is an aquarium fan. This aquarium fan has a 2-speed control system that promotes cooling by 1 or 2 degrees Fahrenheit.

Breeding issues

They aren’t likely to breed, and Guppy fry can’t survive in very cold or hot water. It’s because of the low energy they have when confined to cold water. It is necessary to obtain a suitable temperature for breeding conditions.

Keep it with fish with the same water temperature range.

Keep Guppies with tank mates that live in the same temperature range so you won’t have future problems with fish exposed to high or low temperatures. Temperature is necessary for a Guppy fish to survive in the best water conditions and to reproduce correctly.

What is a suitable temperature for guppies to breed?

The water temperature should be around 77 degrees Fahrenheit. When breeding, try to use the same temperature as usual in your aquarium. Fingerlings must thrive for breeding success; this can only be achieved with the correct and stable temperature; higher temperatures lead to faster growth, and lower temperatures lead to slower growth, both of which are not desirable when breeding fish. Everything must be sized correctly.

Points to remember

If kept in cold water, Guppies in domestic aquariums will face other illnesses, such as behavioral difficulties in reproduction and growth, and suffer slowly and silently. It would be best if you did not expose them to unwanted temperatures. Therefore, keeping them in warm water without variations is the best way to provide them with a suitable habitat for optimal growth. Exposure to irregular water temperature can be fatal.


The quality aquarium heater will help keep the water temperature stable and between 72 and 82 degrees Fahrenheit. Guppies live in warmer waters. The maximum temperature that can be maintained is 84°F; that temperature is used mainly for therapeutic purposes. Check that the guppy temperature and other water parameters match that of fish in a community aquarium. I hope this article answers your questions about guppy temperature requirements and has given you some ideas of other fish that also like warm water. When choosing a fish for your community aquarium, make sure they match each other.

[Methods & Guide] How to oxygenate a fish tank without a pump?

oxygenate a fish tank without a pump

A low level of oxygen in the fish tank can make it difficult for fish to breathe. At high concentrations of oxygen dispersion, bubbles form in the lining of the skin, gills, and eyes. Therefore, adequate levels of oxygen are needed to keep a fish healthy.

How do I Oxygenate a fish tank without a pump?

In an emergency, you can increase the oxygen in your fish tank by pouring water from a high height using a cup. When oxygenation is low, you can do a 50% water change. If there is barely enough water flowing into the pond, algae and plants thrive by reducing and lowering oxygen concentrations. Insufficient airflow can reduce life expectancy, causing fish to become very stressed and die quickly.

How to increase oxygen in a fish tank

Undoubtedly a big mistake by any first-time aquarist is not feeding fish sufficient oxygen. In fish tanks, proper oxygen can be essential for healthy fauna. There exist various reasons why oxygen levels have dropped in tanks. Fortunately, there are still ways to correct the issue and prevent it. Learn how to increase oxygenation in aquariums to keep fish alive.

How do I get more oxygen in my fish tank?

Lowering oxygen levels can cause serious health problems and can even kill fish. There are a few possible causes for low oxygen in fish tank conditions, but fortunately, there are several solutions to the problem. We have to talk about getting more oxygen into your aquarium and simple solutions to fix low oxygen levels.

oxygenate a fish tank without a pump

Signs of low oxygen in a fish tank

Your fish’s rude behavior should alert you. Low oxygen is generally not a problem in a well-stabilized and reliable aquarium. Certain fish occasionally “choke” underwater; this problematic behavior occurs when fish stay close to the water’s surface and continually try to swallow more water; this is a vital sign of poor oxygen water.

Causes Of Low Oxygen In A Fish Tank

Many fish will cause an imbalance between oxygen absorption and carbon dioxide buildup in aquatic environments. Insufficient aeration can cause reduced water movement, reducing the level of gas exchange. Stagnant aquarium water can also pave the way for algae overgrowth. Clogged filters and media drastically reduce filter flow capacity. Adding antibiotics to treat illnesses can also cause decreased oxygen levels. Live aquarium plants provide oxygen when your need is met. Plants cannot convert carbon dioxide into oxygen if lights are off for at least six to 8 hours a day.

Ways to increase oxygen in the fish tank (Permanent solutions)

HOB filters can help your aquarium maintain proper levels of oxygen. They’re relatively small & relatively easy to use. Use a sprayer to distribute water through the tank evenly. A fountain can help increase the oxygen content in your lake. Use an air pump to bring oxygen inside the tank through an air stone. The air pump collects the air and ejects it into the tank through the stone.

Some tips

Fish usually go on a surface to consume oxygen as they have the most dissolved oxygen at the surface. A fish may survive for only some days without oxygen. If your fish comes off to the water surface looking to breathe, it will signal that the aquarium has inadequate oxygen. Significant water changes (up to 50%) of the tank water are an excellent way to add some fresh air; this way, you can effectively deal with the low oxygen level present in the tank.

What causes a lack of oxygen in fish tanks?

If you have a fish tank with high-temperature water, this could be causing problems with oxygen. Water at high temperatures does not retain oxygen like cold water. The lack of moving water causes a low oxygen level because the movement of water aids in the gas exchange of the aquarium water.

How does oxygen dissipate in a fish tank?

Photosynthesis is how plants use lights and carbon dioxide to generate food for themselves. As a byproduct, they also generate oxygen which will remain dissolved in water. At the same time, gas exchange between the environment and the water surface is constituted in a constant diffusion effect. Oxygen enters through the air into water, transferring carbon dioxide.

How much oxygen do fish need?

The safe level of oxygen depends on fish species. Bottom-dwelling shrimp require 1-2 grams of dissolved oxygen to live. The widely accepted standard for DO is 4 – 5 mg/L fish can suffocate under three mg/L. Healthy tanks should have 70% oxygen saturation. Fish can thrive and prosper without problems if water is provided with oxygen. But trouble arises when the water has become supersaturated. It’s a root cause of gas bubble diseases. In the fish tank with high amounts of oxygen, bubbles appeared forming on the body tissues of the fish. You can see the bubbles under their fins, noses, and ears.

Signs Of Too Much Oxygen In A Fish Tank

Fish native to slow-flowing or stagnant waters can become overwhelmed by increased circulation of water. By definition, Bettas is no big fan of filters having high flow rates. The constant motion of the filters and the bubbles may cause too much water turbulence. If you see fish floating in the current, it’s time to reduce aerators. It is a non-infectious condition that often creates trauma and stress. Provide the fish with a good escape and shelter.

What’s the difference between oxygen and aeration?

Oxygen refers to gas exchange that occurs at the surface when water meets atmospheric air. Aeration covers oxygen production but is linked to the motion of water inside a fish pool (water flow/current). While oxygenation occurs directly at the surface, water aeration would effectively distribute oxygen-rich water evenly within the tank. You can use oxygen test kits to test your aquarium’s oxygen levels.

How do I increase the oxygen in my tank in an emergency?

Your fish is suffocating through lack of oxygen, and they need immediate oxygen. Here I’m going to tell you how to get more oxygen inside your tank quickly. When water is pouring from the top, it will aid in aerating it in water and increasing its tanks’ volume. Another way to increase the water is to do a big water switch (up to 60%of the tank). Use ice cubes to cool down the water by putting ice cubes in a Ziploc bag. An emergency battery air pump can move the water around during an electrical emergency.

How do you know if your tank has a low oxygen level?

Some signs can warn you if fish tanks have low oxygen value. Fish come and gasp on the surface if they reach the surface of the water and gasp with a large mouth opening. If your fishes were breathing slowly and you saw more quick gill movements, this could indicate an aquarium’s loss of oxygen levels. Fish move around less; they swim less and slower than usual.

How do I know if oxygen is low?

You can tell if a fish tank lacks adequate oxygen through the behavior of its fish. A good test kit can measure the levels of dissolved oxygen in the water; the aquarist should monitor the oxygen levels in the fish tank for indicators of low grades.

Some causes and solutions of low oxygen levels

Several factors can affect the low oxygen level in the water, but each one has an acceptable solution. Adding air stones and an air pump is always a possible way to increase aeration. They would be the best solution significantly if they would help mitigate the various issues we talked about.

oxygenate a fish tank without a pump


A small-sized water reservoir should have enough oxygen to spawn a small amount of fish. There are too many fish in the tank to support oxygen consumption. The solution is a smaller population of fish for larger tanks. You can also separate fish and house them in more than one tank. Air stones and air pumps can undoubtedly help with this problem too.

Too much waste

When too many fish are in one tank, they leave a tremendous amount of waste. A discharge of ammonium and nitrites in wastewater causes oxygen depletion. In addition, too many algae in the water are unable for the water to absorb oxygen. It would only require water replacement and cleaning the tank. A clean filter should eliminate a lot of waste, which also gets rid of any harmful algae infiltration tanks. The disposal of the trash in the tanks could increase the storage capacity of oxygen.

Not enough water movement

Oxygen from stagnant water will dissolve in minutes. This is especially true with tanks because the gas exchange is non-existent. Injecting air into the system will encourage water circulation through the tank and contribute to a positive exchange of oxygen at the top of the tank. The problem can be solved by cleaning a filter that doesn’t work, or you might also need a more powerful filter.

A high water temperature

Hot water retains much less oxygen than cold water. Many of your fish or plants require hot water for their survival. If the temperature is too high, you can do a 50% water change. Some ice cubes can be placed in a plastic bag and placed in an aquarium. Have a good water thermometer so you can observe the water temperature and turn off all lights and heaters in your aquarium.

Can you have too much oxygen in a fish tank?

There can be a gas bubble disease if the gas bubble leaks out of the solution inside the fish. Air bubbles can also generate under the skin or around the eyes. Always make sure that the aquarium has enough oxygen, correctly sized for the species that inhabit it.

Too many live plants

If there is light, plants release CO2 from the water and generate oxygen. But when the light bulbs go out, so do plants that absorb oxygen and produce CO2.

Why do my fish gasp for air?

This can sometimes mean that fish are dying from having too little dissolved oxygen in their aquarium. Sometimes, panting can mean other illnesses as well – inadequate water temperature or contaminated skin. However, the most common scenario for a panting fish is the need for a little more oxygen.


Some chemical products used by water treatment companies may affect the oxygen level in water over time. If you mix dissolved oxygen in water, check for the ingredients and the label.

How do I check the oxygen level in my fish tank?

The most effective way to measure dissolved oxygen in fish tanks is using a water dissolved oxygen meter. Without a test, it is impossible to tell. The item can never be seen in sight by eye, smell, or feel by hand. An oxygen meter is the only answer.

What are the signs of low oxygen levels in fish tanks?

Fish keepers usually anticipate this phenomenon by closely following animals’ behavior. Fish will exhibit some visible signs if tank oxygen is low.

Gasping on the surface

Occasionally the fish, including Bettas, Gouramis, and catfish, come to the surface and take a gasp of air. They won’t stay on the surface any longer unless something goes wrong. Some other fish will lie on the substrate when oxygen levels drop. If you see a fish species panting toward the surface, it could indicate that your tank is out of oxygen.

Difficulties in breathing

The fish “swallow” the water that passes through the gills and filaments, where oxygen and carbon dioxide are exchanged. Excessive gill movement and labored breathing indicate lower oxygen.

Slow fish movement

Insufficient oxygen can stop fish from swimming naturally. They will slow down your movements and appear stagnant. Although some fish don’t constantly move, it can signal low oxygen when you see this behavior frequently. Oxygen is the fuel that keeps animals alive.

Lack of appetite

Under low oxygen conditions, fish don’t eat as often. If you notice fish in your aquarium that doesn’t eat voraciously, this could indicate health problems.

Tell me the cause of low oxygen levels?

You know the signs of lack of oxygen inside your tanks and now let me reveal the causes. If it’s easy to find and determine the cause of the problem, it will be resolved quickly.

Waste accumulation

Overstocking, overfeeding, neglect, and poor cleaning are major causing of waste problems. Uneaten food that accumulates due to a lot of overeating and clogged filters can also help accumulate waste. Bacteria need more oxygen to break down waste, thus decreasing the aquarium’s oxygen-carrying capacity. Oxygen will be lost, contributing to the formation of toxic gases, including ammonia, that can be lethal to fish.

High water temperature

Coldwater can carry much more oxygen than hot water. Many fish in tropical aquariums survive comfortably in a range between 75 and 80 degrees. As temperature increases, the strength of oxygen decreases.

Heavily Planted Tank with Low Lighting

Plants consume carbon dioxide in water and release oxygen in photosynthesis with sufficient light exposure. When there is no light, they absorb oxygen, but they emit carbon dioxide, and they emit carbon dioxide. Algae also work the same way as live plants, so the right amount of light is essential to check algae activity and maintain good quality oxygen.

Lack of water movement

Aeration is a way in which oxygen penetrates the water. Oxygen typically is rich near the surface but doesn’t reach the bottom for lack of agitation or circulation. The movements of the water help to oxygenate the entire amount of aquarium water. Stagnant aquarium water will lead to low oxygen levels.


Overstocking is often a cause for lack of oxygen. Too much population requires even more resources. Most Beginners make this mistake at their initial stages, as overstocking can even lead to other problems.

Pour water from a height.

The higher the elevation, the more oxygen will enter. Repeat it sometimes. You can also do it while adding more water when the water is changed. Position a plate on the substrate to prevent mixing it into the water.

Use of certain chemicals

Common chemicals and additives may cause low oxygen levels. Therefore it’s always beneficial to be retrospective whenever you use chemicals in your aquariums.

Water change (50%)

A water change replenishes the oxygen in your aquarium. Change 50 percent of water and use fresh water.

Agitate the water manually.

Stirring up surface water is a straightforward way to increase the levels of oxygen.

Solve the problem with live plants in your tank

Adding more light will help living plants absorb more CO2 and increase oxygenation. Try to balance the number of plants in the aquarium with the amount of oxygen in the water.

Check the water temperature and make adjustments.

The water temperature must not exceed the ideal parameters to keep the chosen species. Usually, oxygen will be low if the temperature is high. Always use an accurate aquarium thermometer to monitor your water temperature every day.

Create more movement in the water

The use of powerheads creates simple movement in the water. If you already have a filter and your fish don’t get enough oxygen, you can add a powerhead. As an alternative, we can even use air pumping as a supplement. If your tanks are more significant, you may want more powerheads as the size of your tanks gets bigger. Using small overhead rocks or air pumps, add water flow at different locations in the tank to ensure a steady flow of water into the tank.

Proper and frequent tank cleaning

Fish need some bacterial diversity in the aquarium to survive. Clean your aquarium, scrape the inside of the glass, vacuum the substrate and change the water. Use paper towels to scrub the front of the tank. Use the toothbrush exclusively for cleaning items in the tank.

Solve overcrowding

There may already be excess capacity in fish tanks due to a lack of oxygen. Transfer other fish to a different tank to reduce overcrowding.

A solution to too much oxygen in a fish tank

A good quality water filter should have an adjustable flow rate. Remove aeration instruments one at a time until you settle on a system that maintains aerated/oxygenation at an optimal level.


If the water temperature reduces oxygen levels in the fish tank, this can be controlled by lowering the temperature with ice cubes or proceeding with a water change. The permanent solution to low oxygen levels includes using a filter with a spray bar or an air pump. Using a fountain is a great way to oxygenate your lake water.

How to Care For Your Fish Bowl: A Beginner’s Guide

How to Care for Your Fish Bowl

Let’s get you started with fish-keeping with confidence by learning the basic steps and essential care tips on how to care for your fish bowl in this beginner’s guide.

Many hobbyists would consider a bowl a cheaper alternative to a glass aquarium. Indeed, these fish are not always healthy or allow a suitable habitat, especially tropical fish when kept in small closed habitats.

Let’s find out why they don’t provide an appropriate environment for fishing in your home. For more details on how to care for your fish bowl, keep reading this post where we’ll talk about fish that live in unfiltered tanks.

How to care for your fish bowl – What you need to know.

If you need to keep your fish in a bowl, try to provide a minimum size of 10-gallon containers so the fish can live better.

Lastly, one can use a sponge filter and some live plants to aid in the filtration and general water conditions. The sponge filter provides a place for beneficial bacteria to grow; it will also help aerate and move the air around the water, and living plants will help eliminate some nitrate in your body.

Small heaters can be used in a bowl, and Water temperature is an important parameter to keep an eye on your fish tank because of the constant fluctuations.

How to Care for Your Fish Bowl

Fishbowls restrict oxygen levels.

Food waste, clogged filters, and excessive algae growth can cause decreased dissolved oxygen and reduced gas transport capacity to the aquarium. In bowls, it is necessary to consider a limit to a gallon of water.

Not all fish species will adapt to space. Maintenance is easy; carry out water changes periodically to ensure that the fish’s oxygen levels are correct. The most suitable way to maintain the levels correctly is to have an air pump.

Betta fish can live in a fishbowl without a filter.

Bettas are the most popular aquarium animals that can live in a fish bowl without filter. Bettas come equipped with labyrinthine organs that allow them to breathe atmospheric air.

It is still necessary to maintain the purity of the water bowl. It is vital to keep a good filter and have good conditions for water. Typically, partial water changes should be done at least every five days. Betta fish, the Siamese fighting fish, lives in an ideal habitat for up to four years.

A few logs, the proper lighting, and the burrows keep your fish healthy in a bowl. Bettas like aquarium plants, so add plants to your fish bowls.

The limitation fish bowl fish

Fishbowls are best suited for the minimalist setup (this means we don’t use filters and heaters). Also, since you are using bowls, you only have a small water volume, typically 10 gallons maximum.

You must make up for the lack of filters and heaters with regular cleaning, changes, and monitoring of the water conditions. We suggest starting a setup if you have some experience in fishkeeping.

The water in the fishbowl will require regular changes instead of traditional cleaning of filters and so on.

The result is that you make up for the lack of filtration and heating by continually changing the water in the bowl. But this doesn’t allow you many species of fish in a gallon bowl.

Zebra Danios fish can live in a bowl.

Zebra Danios are gray with gold color and five blue stripes. They typically prefer temperatures in the 77 – 95°F range. Zebra danios should be kept in a minimum of three gallons of water.

Sand and gravel would be ideal substrates based on them, as fish prefer more alkaline materials. Plants like Amazon sword plants or java ferns increase the oxygen in the aquarium water.

You’ll need several of them and can opt for a 10-gallon fishbowl for a school of danio. The maximum size fish should reach about 2 inches.

Can Ember Tetras fish live in a bowl?

The Ember Tetra is also known as an incandescent tetra for its coloration. In nature, the tetra-ember swims in swamps and slow-moving rivers.

The fish will bloom in the bowl. Add floating plants, such as the hornwort and java moss, as well as java ferns, to the bain-marie.

Similar to other small fish, it is possible to overfeed your tetra and have water damage. Consistent water replenishment is key to having a tetra bowl. Tetras are sensitive to changes in pH, ambient lighting, and temperature.

Fishbowls are not easier to maintain

Some believe that a small bowl is easier to maintain than an aquarium. This is not the case. Fish bowls, especially if they are over stocked with fish require high maintenance.

As many knowledgeable aquarium traders will likely tell you, the vast majority of attempts to keep fish in a bowl can end in either one of two ways: one keeper quickly finds the bowl too tricky to maintain and upgrade to a traditional aquarium. The bowl is too small to keep, so keepers often find it too difficult to control.

How often do you change the water in a bowl?

Knowing how to care for your fish bowl requires an understanding of water parameters and the need for regular water changes. Partial changes should take place weekly, preventing the water parameters from becoming critical for fishbowls. There are products that can be bought and added to the system to condition the water.

That is why betta fish or danios are often recommended, as they are the best fish in these bowel conditions, as partial changes can be made once a week.

These fish deal well with poor filtration, as they are resistant, but it is necessary to change the water at least once a week.

Best fish bowl fish: guppies live in a bowl without a filter

Guppies are good to live in a bowl. Of course, the water change maintenance should be constant, but the concern will be far less than with other types of fish.

The guppy is the easiest fish available to hobbyists and beginners. These beautiful fish are available in fantastic color varieties and they are pretty hardy.

Guppies also reproduce quickly and accept fish food very easily. These fish are resistant to water parameters and when there are fry, they can be kept at an initial stage in a 5-gallon bowl.

The best fish to keep in a fishbowl

White Cloud Minnows are small but active fish with small red tips and like to swim in schools. They are super strong and very healthy fish that can live in not the best water quality.

They can survive without heat, so they’re not a problem unless it’s not necessary. Adding snails or shrimp does not affect the life of the fish.

You could keep three tiny fish in a 10-gallon bowl of live plants, and it would look fantastic. They are friendly and peaceful fish, so add some snails and shrimp to your bowl.

How to Care for Your Fish Bowl

Final Thoughts – How to Care For Your Fish Bowl

Ammonia and other substances like nitrite quickly accumulate in smaller spaces and poison fish. An aquarium can be maintained with weekly water changes and the installation of a sponge or air pump.

These pets can feel safe among plants like Java Fern, Anubias, and Java Moss, which is beneficial to water quality. In this article, we concluded that several fish species could live in a bowl, but it is not recommended to keep them that way. Ideally, in emergency cases, use this system.

How to Soften Aquarium Water – Best Safe & Effective Methods

How to Soften Aquarium Water

The temperature of the aquarium’s tap water can affect the hardness of the water. There are five ways to reduce the hardness of aquarium water. Reverse osmosis, rainwater, peat water, driftwood, and water softening pillows are standard methods of How to Soften Aquarium Water. Each means has its advantages and disadvantages and may not have been effective in all use cases. Detailed descriptions of these types of water softeners will be presented below.

What is water hardness?

The higher the concentration of minerals in the aquarium water, the more challenging water is considered. The Amazon River has a GH of up to 10 mg / L. Unlike African lakes, which can reach 50 mg / L., Fish are physiologically accustomed to the water conditions in their natural habitat. It is up to us to replicate these conditions if we hope to get them back from their cages. Water hardness is one of the parameters that some soft water fish correctly need. In hard water, it is almost impossible to raise and spawn mild water fish because the vast differences in water hardness between aquariums and native habitats are reasons that directly affect the physiological and osmotic system of the fish.

How do I tell if my aquarium water is hard or soft?

There are several ways to find out which aquarium water is hard or soft. A method of evaluating test strips is scientifically advisable and more economical. You can call a local water service to have the person ask if your water supply is hard or not. Online maps also let you know if the ocean is soft or complicated in your area. You can find them in tests – and you can get water tests in fish or pet stores.

What causes aquarium water hardness

Many aquarists use tap water in their waters. The content of natural minerals in natural water sources varies widely across the world. People use crushed corals or oyster shells as a substrate to increase the aquarium water’s hardness intentionally. If the rocky material is formed by limestone, the effect is made to make the water hard. In short, what makes your aquarium water harder or softer is what we call the alkaline reserve.

How to Soften Aquarium Water

How to buffer my aquarium water with carbonate and bicarbonate ions

The hardness of KH-carbonates is responsible for the “buffering effect” in aquarium water, which can keep the pH stable, even with the addition of acids or bases (alkaline compounds). In this way, pH is closely related to KH. Buffered waters present proportionally greater stability and formation for bicarbonates; – the presence of bicarbonates begins to occur at a pH above 4.4, and their transformation to carbonates begins at a pH above 7.8; – remember that acid carbonates/bicarbonates are formed first and then neutral carbonates. If an aquatic system has a high KH-carbonate hardness, it will be tough to change its pH level, while if it has a low KH, it is complicated to keep the pH stable, as the water is subject to significant pH variations. Some think that having a high KH-carbonate hardness will also be high, but this is not true because if we have several acidic compounds, which are higher than the absorption capacity of KH, the pH can be extremely low. It may have high hardness in KH-carbonates, e.g., ex. 120 – 125.0 mg/l, i.e., about 7 degrees/KH, but with a pH in the range of 6.5 or even less, therefore tending to acidic. The opposite is also possible, as we can have alkaline compounds with few carbonates, that is, high pH and low KH-carbonate concentration. You must also check any problem with pH for hardness in carbonates/KH. There is no ideal KH value to keep the pH stable, as this depends on what other compounds there are dissolved in the aquatic system and in what quantity. Generally, a KH of 4° (i.e., 4 degrees x 17.8 parts per million ppm = 71.2 mg/l) is sufficient to keep the pH stable, therefore around 70.0 to 80.0 mg/l hardness carbonated/KH. Attention: generally, but not always, understand.

Why do you need to soften aquarium water?

Aquarium fish species don’t have as much flexibility for salinity, pH, or nitrate level parameters. Levels beyond the comfort range for these water quality indicators run the risk of endangering the fish and possibly causing death. Aquatic hardness is a pond parameter that most captive fish adapt to. Soft water aquarium fish can survive in hard water. If you choose the fish species that need soft water, consider changing the water source rather than using expensive treatments. Using Reverse Osmosis (RO) water for mixing is an option, as is using a combination of tap water and distilled water. Some aquarists even collect rainwater, which is naturally soft and acidic; however, be very careful as the likelihood of it being contaminated can be high.

Use of rainwater in the aquarium

Rainwater is a gift, but unfortunately, not everywhere in the universe. You can mix tap water with rainwater in the right proportion to get the desired range of pH and DHG values. Rainwater storage tanks have safe, sterile, and quality materials to minimize contamination present in the water. Thus to water without impurities harmful to fish. The storage tank must be sized to contain water during the dry season. Rainwater is usually found in a clean, good-sized container, sometimes covered by the sun. When it starts to rain, its lid opens to let in the rainwater. Rainwater is a free source of water that you can use in the aquarium—remembering that rainwater, in large cities, tends to be always soft and with an acidic pH.

How to soften aquarium water with security

Softening water in aquariums is usually a slow and gradual process. This ensures that the fish do not experience dangerous side effects due to unstable water quality. It’s best to soften your aquarium water slowly and gradually to reduce the harmful effects – especially for your pet. Softening the water is more important than completely changing the overall hardness of tap water. The weekly test should help inform you of any noticeable GH, KH, or pH levels fluctuations.

How to soften water in an aquarium with driftwood

Using driftwood is a natural approach to reducing hardness in aquarium water. Malaysian driftwood contains many tannins and is suitable for softening water. Tannins tend to fade with water changes gradually. If you test water hardness and see an increase in water hardness, even if the wood is absorbing water, you can substitute floating wood. Another common alternative is tannin-producing leaves, mainly Indian almond leaves.

Peat moss for softening aquarium water

Among the natural ornaments, it is known that driftwood helps soften the water and thus lower the pH; being widely used in tropical fish aquariums and used together to soften the water is peat, usually placed in a bag inside the filter or in a waterway. A peat moss softens the water and reduces hardness (GH). You can buy it at aquarium stores. However, it tends to be a little more expensive locally. It is much more economical to buy it from garden stores.

Reverse Osmosis (RO/DI)

The RO / DI (Retro – Deionized Osmosis) system passes water through a membrane filtration unit to make the water 100% pure. RO water contains zero hardness which cannot be used in aquariums. Although it is initially expensive, it can help you save time and money. RO water also has no hardness, so it is possible to mix or remineralize RO water by adding minerals in an ideal way for your aquarium. Once you start making RO systems, managing the hardness and pH of your aquarium, the water is very manageable.

How to Soften Aquarium Water

What you need to know carbonate hardness kit

General hardness (GH) describes the level of calcium and magnesium ions found in water. Carbonate hardness (KW) describes levels of carbonate or carboxylation. The higher the KH concentration, the greater the buffer against acid. This prevents the pH from dropping and helps keep the alkaline water. It is essential to study the effects of calcium and magnesium in aquarium water. Some fish grow well in hard water, but certain fish such as gouramis, tetras, and cichlids survive best in soft water. Remember that most fish you buy is probably not wild-caught, so they’ll be OK at home.

Chemistry made for general aquarium hardness water

About industrial water softeners suitable for aquariums, it is essential to read the label correctly because as reliable as it is, the change in your aquarium can be none or too sudden. Because it depends on what was recently posted and talked about. Several factors influence the overall hardness of the water. And incorrect use of these products can cause harmful and fatal effects to your fish. This process is gradual, changing quickly, it will affect your fish’s osmotic system. As tolerable as it is, it can lead to death.

Conclusion on the effects of water hardness in aquariums

We know that water conditions, in general, are a sum of factors until we have the desired result for our fish’s environment. The necessary parameters go beyond temperature or pH; they talk about minerals dissolved in the water, alkaline reserve, interaction between all these parameters, and even the partial exchange water of the aquarium. Whether your aquarium water will be acidic or alkaline will depend on the desired fauna, each fish species has its preferences. Although they are pretty resistant to changes in hardness, that doesn’t mean that this is not harmful to your system in the long run. And it is essential to contain good filter water to maintain generally ideal conditions, as the poor quality of water filtration will also influence these parameters.

Fish that don’t need filters (Everything You Need To Know!)

Fish that don't need filters

Fish that don’t need filters:  Of course, the cheapest tanks are unfiltered, and most people want to know if they can keep their fish in an unfiltered tank.

Every fish does not need oxygen to breathe. But some species can absorb oxygen directly from the air in addition to oxygen dissolved in water.

Among them are the Bettas, Gouramis, and other Anabantidae. Let’s talk about the requirements of these fish and what precautions we should take when keeping fish that don’t need filters.

Why do fish need a filter?

Fish that don’t need filters are much more tolerant to polluted water. The main excretory product of fish is ammonia, which they release into water directly.

This increase in the ammonia level in the water depends on the number of feeds given to the fish, the quality of the meals, the excellent acceptance of the feeds, correct maintenance, the size of the fish, and the volume in the tank.

The less they feed and excrete, the less they pollute the water. Some fish are also hardy, which means they can survive even in unfavorable conditions. But that’s not to say that, in the long run, it doesn’t cause severe problems for them or might even malfunction.

How fish breathe underwater

The gills or gills facilitate what is called water breathing. The water enters the fish’s mouth and goes to the gills. There, the blood receives oxygen. It then expels carbon dioxide through the operculum, the holes on each side of the fish’s head.

Examples of fish that don’t need filters or heaters

A goldfish is one of the most common aquarium fish. Does not require filtration or an electric heater. Guppies are excellent pets that can survive without heaters or filters.

The Danio zebra is an inexpensive fish that makes a good pet for an aquarium. If you want to maintain a healthy aquarium and well-stabilized water parameters for your fish, you should change the water frequently.

It is always essential to clean the bottom of the aquarium, where waste is concentrated. Partial water change helps bring ammonia levels below a critical level.

Why do fish need a water heater?

Fish depend on the temperature of the water in their environment to control their internal temperature. In their natural habitat, some fish prefer cold water, while others prefer warmer water.

If you have cold-water fish in your aquarium, you don’t need a water heater because their temperature is suitable. For cooler climates but you want freshwater fish, a heater is required.

Now that you understand the reasons for using the filter and heater, I’ll give examples of fish surviving without them. Examples of fish without a heater and others without a filter.

What kind of fish can live in a bowl

Most bowls are tiny, without filters or decoration. Fish that are very hardy, tiny, and potentially cold-water species are recommended.

Tough fish like the white cloud goldfish can handle variations in water parameters more smoothly. Small fish in small space and less water and can make great bowl choices.

Coldwater fish may require a daily routine water change. If you don’t have a heater, you probably don’t want a fish that doesn’t need a constant temperature of 78F like a Betta fish if you can’t heat the water.

Smaller species such as Scarlet Badis are good choices.

The best fish to keep in a fish bowl

Bettas are by far the most suitable fish for bowls. We also have White Cloud Minnows are small fish but very active, with small red tips, but they like to swim in shoals.

They are super resistant and can tolerate significant variations in water quality for some time. They live in cold water, and therefore you don’t need the heater. If you add some snails or shrimp, they won’t bite these animals.

Types of fish that should not be kept in bowls

Fish that are predatory and large should not be thrown into bowls. This type of fish requires a much more intense filtration and oxygenation system to supply its minimal needs. Here are some excellent examples of fish you should avoid: The oscar fish, discus, angelfish, plecos, and more.

How we reviewed the following fish that don’t need filters

We have experts that have worked on animals in pet stores who have observed the different species. The main characteristics looked at were prices, colors, and the ease of maintenance. We’ve tried being as objective as we can about these fish.

Betta fish are perfect for a bowl.

Bettas are a fish that don’t need filters. They are an exotic fish, famous for their long, colorful tails. The male is highly aggressive with fish of the same species, while females can live with others. Contrary to what many people believe, it should not be kept in aquariums smaller than 10 gallons.

It is a small fish, which stays alive in a bowl without a filter. Still, it is necessary to keep it with heaters to avoid sudden fluctuations in temperature, depending on where you live, especially in tropical regions where temperatures fluctuate daily.

But the most important rule is to always keep one betta fish per bowl. It’s a fish with an enormously vast range of colors.

Fish that don't need filters

Least Killifish

These small fish are very easy to care for and are an excellent choice for those looking for a species they won’t spend a lot of time with.

Due to their small size and peaceful nature, you can have them in large groups and with a wide variety of other species.

Many modern aquarists know that these fish are average fish, especially males because they have them in their tanks. There are big fans of killifish, especially if you plan to keep the water temperature lower.

You can have a variety of aquatic plants and mosses; they like, decorate, and help in the general stability of the water quality, making partial changes less frequent. It’s a fish with a wide range of colors.

Fish that don't need filters

Zebra Danios easy to take care

Zebra Danios has a loyal following in the freshwater aquarium community. It’s a lot of fun to see these fish playing and swimming in groups.

You can keep them in small, warm aquariums without worrying about their diet or interaction with other fish. With a temperature range of 20°C, it is possible to keep these tanks at lower temperatures without problems.

They are not fish that require a biological filter if the water changes are correctly done. These fish are important because they have a longer lifespan. They have very soothing properties that you can combine with many different plants.

Fish that don't need filters

The Danio Celestial

Galaxy rasbora is one of the few freshwater species that we keep in cold water tanks. These fish are peaceful and friendly.

The Danio Celestial Pearl, a famous name, is an exquisite species that many aquarists love small fish. Do not exceed 1.5 inches. So it’s pretty evident that they don’t need a lot of gallon tanks. Their colorful pattern makes them a fantastic choice for any aquarium looking for some color.

Despite their unique characteristics, these fish sometimes don’t stand out from others and can become challenging to identify in the wild based on their appearance.

These fish are best for small, well-designed aquariums. They were widely used with shrimps and low vegetation aquariums. They usually stand out more quickly in aquariums with a white background and green plants.

Fish that don't need filters

Empire Gudgeon

Empire Gudgeon is full of exciting colors and behaviors. Plus, it’s easy to maintain. You will need some maintenance from time to time, but if you have built an excellent habitat. They can thrive in all water conditions and are easily kept in cold water.

They also have beautiful colors. Most aquarists know them because most like them in small bowls, up to 10 gallons. They adapt well and have unique and striking behavior.

They are very active and interact with the aquarists, especially in the feeding frenzy. And it’s another variety of fish that lives well without a filter.

Fish that don't need filters

Paradise a strikingly colored fish

Fish with a striking appearance, drawing attention due to its blue and red stripes. It’s not a very peaceful fish; it can be territorial. Keeping it in a minimum school of 6 fish can help reduce aggression.

A properly sized aquarium is also essential. They are resistant to variations in water parameters, quickly adapt to various types of feed, and are very fond of plants in their environment, which also helps avoid any conflicts.

Cherry Shrimp in a bowl

When considering fish that don’t need filters, why not consider shrimp.

Neocaridina davidi has an excellent reputation among fish farmers in Asia for its bright, Skittl-like tones. They can be easily bought and sold at pet stores.

Start with 10 or 20 prawns for a 10 gallons bowl, make sure they keep enough calcium and minerals in the water, and soon you’ll have beautiful baby prawns. Shrimps were originally brownish-gray in appearance but have been cultivated in many.

They will not exceed 2 inches. Different colors like blue, red, white, red-orange, and black. They can be combined with galaxy rasboras, but you must pay attention to the general quality of the water, maintain more intense maintenance and try to offer the best quality feed possible. And it doesn’t need a heater or filter.

Medaka Ricefish

This fish carries two names. Medaka rice fish and Japanese rice fish. Some believe that some of these fish should technically belong to the killifish family.

This species is an excellent choice if you want a fish that will get along with everyone. This fish is simple to feed and maintain, and it also reproduces quickly.

This is undoubtedly a species to consider for fish to put in bowls with little water gallons. They are very resistant to temperature changes, in addition to having good tolerance to suitable pH ranges. They adapt very well to other fish of the same size and behavior.

Pygmy Sunfish is an excellent small fish.

The pygmy Sunfish is a cold-water fish; it handles low temperatures very well, it doesn’t do well when temperatures are high. They have striking but straightforward colors.

It is a popular fish for its distinctive appearance and ease of care. It is a species that has a dedicated following among aquarists for many different reasons (besides color).

If you love the color red, green, and blue, you will love this fish. This species is highly vibrant and will add a new visual dynamic to any aquarium they live in.

It is remembered that colors vary from females to males. It has a peaceful behavior and loves to be among plants and mosses.

The curious kisser fish

Fascinating fish are due to their behavior of “kissing” other members of the species. This behavior is believed to be linked to dominance disputes among fish.

It is peaceful but can become aggressive towards other Gouramis. It should be kept in large aquariums due to its size, reaching many tens of centimeters.

Pethia conchonius, the famous barbs.

Pethia conchonius is a fish species whose adults are found in a slightly lotic environment, but they occur in numerous types of habitats, from streams to deeper water tributaries. Distributed in Afghanistan, Pakistan, India, Nepal, and Bangladesh. Reported from Myanmar.

Introduced around the world and very popular with hobbyists. It is one of the most resistant barbs, undemanding, and impressive coloration during the breeding period.

Wild specimens vary in color and size according to the region of occurrence. Selective breeding has produced several ornamental strains, including long-tailed, super red, neon, and gold forms.

It has also been hybridized with some congeners, although apparently, the offspring of such experiments are infertile.

A one-sided livebearer or Jenynsia

The one-sided live bear is a simple but elegant fish that can thrive at cooler temperatures. This species is peaceful and hardy. It is usually best to store this species exclusively in a 10-gallon tank.

Its name comes from the relationship between the two sides. Its behavior is quite exciting and should please any breeder! If you are interested in creating, it might be of interest to you, if you will.

They are known as cold-water species. It thrives in high-density cold water in aquarium waters. It is a genus of freshwater fish in the Anablepidae family.

Like Anableps species, they are unilateral carriers: some sources indicate that they only mate on one side, “right-handed” males with left-handed females and vice versa. However, other sources dispute this. But it’s a fish that you can easily keep without a filter.

Hillstream Loach or Balitoridae

Mountain loaches (Sewellia lineolata) eat brown diatoms and green algae. Hillstream loaches have more ideal water temperatures and a pH ranging from 6.6 to 7.8.

If you’ve fed them well, you’ll notice their breeding habits, and babies show up everywhere. In addition to eating seaweed, they like good quality Repashy foods in gel and wafer.

They are still water fish, but keeping the partial change at least three times a week is interesting. Quality power and correct light. However, it is a freshwater fish from currents, so, interestingly, you have a circulation pump to keep oxygenation high.

Trichogaster trichopterus – Blue gourami

Peaceful species, when in properly sized aquariums, can become territorial in small aquariums. There are several types of coloration, and fish are considered to be very resistant.

Its behavior will vary from individual to individual, although it is often considered peaceful and recommended for community aquariums. Some individuals can become aggressive as they mature, especially when kept in a small aquarium or a few plants.

Plants in your fish bowl

Plants not only help to improve the appearance of the aquarium, but they also provide many benefits. Aquarium plants go through the photosynthesis process to grow during the day (or when the lights are on).

They absorb carbon dioxide from the water (produced by the by-product of fish respiration) and use light as energy to convert this dioxide into oxygen.

Final Thoughts – fish that don’t need filters

Not all fish can withstand unfiltered water, but the ones mentioned are tougher and more challenging than others. Always keep your fish warm when needed. This way, you can keep your fish for many years – although you cannot constantly filter your water.

The notion of owning fish that don’t need filters or a heater may seem strange to some. The strange feeling that fish are going to die from lack of care.

But this will save you some money and allow you to experiment with maintaining a more natural aquarium.

We are committed to making our guides the best they can be, and we appreciate the help of our readers to help us prevent our fish from being kept in cold water tanks without filters.

How To Keep Betta Water Warm Without A Heater [Full Guide]

How To Keep Betta Water Warm Without A Heater

Fish, like reptiles are cold-blooded, so unlike mammals with the ability to generate their own heat, they can only absorb warmth from the surrounding water. When the water is too cold, swimming and moving becomes difficult for them, so they’ll avoid doing it as much as they can. You may observe your Betta laying listlessly at the bottom of the tank.

Betta fish are a tropical species from the warm fresh water ponds of Thailand. They may go into shock at temperatures below 74 degrees Fahrenheit, though it is usual for them to react poorly when temperatures are 72.

Truthfully, Bettas with no heaters, can survive within reasonable limits, but they certainly won’t thrive. They prefer this. It helps them strengthen their immune system at risk of disease. Changing seasons sometimes can damage your dog’s immune system but it’s not possible. There are numerous factors to take into consideration and we intend on going through a full line of answers and ultimately finding a solution you feel comfortable with. We’ll pass through several lines to give you an objective answer to all the facts. A truly objective question can only be obtained once one examines the facts.

How To Keep Betta Water Warm Without A Heater!?

Let’s examine the disadvantage of keeping a water tank warm without a heater. No method of a way round any disadvantages. We’ve all been fascinated by fishkeeping since antiquity before submersible electrical heating was invented. Victorian tank had flat bottom and was heated by boiling the bottom (very much as a souppot!). Victorian –errahthenia was heated from below so much as a soup to cook from below the water of fish during the Victorian age. Here is the easiest and fastest way of bypassing the heater for good in your aquarium.

How to make your fish tank cold without a roost heater will ensure your day is going smoothly when your electrical cable runs out, you break your aquarium heater or if you never prepare the fuel. At freezing days, your tropicalfish, your bettas etc need a warmer environment to maintain their lives stable. This is where the importance in an aquarium heating tank grows exponentially. Now let it be useful to keep our fish warm at home.

Do Betta fish need a heater?

The Average Betta thrives better in warm water and anything above 68 degrees Celsius is not conducive. Lower temperatures doesn’t actually poison Bettas directly; they just make them vulnerable to the majority of diseases. There are certainly many good alternatives to caring for fish without the need for a heating system. The water temperature in Southeast Asia is about 70 to 80 degrees F on average day. If you live closer to the ocean, filters may not be necessary but the water is recommended but it can be hard on fish to survive on warm water. The fish are not indirectly affected by lower temperatures, they don’t directly effect their lifespans and are not exposed to any temperature variations that may result from the mild-warm water.

How To Keep Betta Water Warm Without A Heater

Tropical fish are big no-no for laying out a tank without an heater. The plants do not well in temperature variations and when stressed by inconsistent water conditions develop dangerous ailments and infections. Corals need UV light and specific water parameters to survive and grow. It is practically impossible to do a minimalist heater-less system when you plan to install coral reef tanks. The constant temperature range needed to control in this class of aquariums is between 75°-80°F in the tank’s water temperature. The range of temperature required to stay within the constant range of 75 – 80 °F is 95 – 80°F.

What happens if Betta water is too cold?

Fishes can’t regulate temperature like humans because they depend in part on the environment for its supply of heat. Betties were fatally unresilient against the cold. In theory, they will be in a coma for a period until water has been very cold which could range in temperature from 50° to 100° Celsius. It basically stops swimming. It sinks to the bottom of the tank. It also hibernates in place until it dies. Betta would do a lot very well if you have a light source nearby and try to get accustomed to being somewhat hot in the cold months. They are fickle and they’re beautiful as they’re delicate.

How long will Betta survive without a heater?

Why don’t animals need more of it even if they have no heat? Room temperature, age of his betta and the health of the animal will be considered. The room temperature should be above 82 °F when the temperature is above this. But if this temperature is so cold or that an older baby gets sick already it can be days before you get too cold and it can potentially be very unhealthy if the water temperature is not below zero.

11 Ways On How To Keep Betta Water Warm Without A Heater?

There are another way to keep your pet warm without having to purchase any heat-up supplies. These steps are honestly fairly straightforward or unspecialized. These are just tips in life and with 2 or 3 of these together you have a real effect! Let’s get down to a few basic, yet surprisingly effective methods to keep your Betja fish warmer.

1.A little sunshine

This step involves using the best source of heat in nature: the sun. Anywhere between 6-8 hours of sunlight will warm the tank up in the perfect way. It also benefits plants and there are a number of issues there. Algae are also plants. It thrives on nitrates and relying heavily on sun for expansion. Their growth in this area can be very explosive and I strongly suggest not staying in the bowl near a window if you are not sure that algae will not appear in your yard if you leave it outside too. It is warmer it helps at photosynthesis. There are also opportunities to use sunlight directly.

2.Use a smaller bowl

Betta fish are fishes not really needing real estate and would be happy and comfortably in their own tiny dishes. This fix is useful because small containers will heat up very quickly. Smaller tanks also lose heat much faster than bigger tanks. How do you keep warm fish? This simplest principle is to introduce continuous, constant heated fuel supply to your tanks for an extended period of time. As long as you can prevent the tank from losing heat too fast you should be ready. It could serve as a solution as a problem as it is a problem and it does not have significant drawbacks.

3.Exploit your aquarium lights

All the half decent aquarium aquariums have good lighting that explains well the plants in your aquarium that call it home. Conventionally these lamps were intended for fish and plants. They might not be hugely strong like any other heater of course, so when used properly they give some great wallops. Leaving the light on for about 8-10 hours can be more hot than you think, they just may heat the tanks well enough to get inside the 80°f range. The only issue with that idea is that the tank starts to lose heat immediately after lights are turned on.

4.Use a poorly optimized filter

Older or poorly optimized filtration can act as heaters. Their poor energy efficiency is a result of them releasing heat. Great for keeping your Betta warm. The only disadvantage is they can not be easily moderated. Overheating can happen and there is no guaranteed way to reduce its heat output. Using older filters older water filters will become extremely hot after about ten hour usage and can sometimes cause water to heat up while entering the tank. If the process lasts long enough it could dramatically improve the filters’ power efficiency. It is not often easy to control and reduce the heat absorbed from the filter.

5.Warm up your tank’s water gradually (temporary solution).

You add a hot hose to your pot to warm the contents gradually and gently. This is not the most efficient option but it remains on the table if heater-free usage is a necessity in itself. It leaves room for somewhat significant fluctuations in the water temperature so you shouldn’t attempt that when bringing up sensitive fish. Water cooling slowly is lower risk than large temperature fluctuations. If you aimed for a temperature of 80 degrees in your aquarium, its water should reach 120 degree. For keeping your tanks warm, fill a sealed bottle with hot water.

6.Insulate the glass walls of your tank.

Insulating insulated glass walls might be an alternative next step. The Styropofoam coating in the back and sides of the tank is not the most pleasing option. The use of insulation film can provide an as-good alternative. This method would help the existing temperature escape but you would need to continue changing the warm water frequently. It is a real drawback of eliminating a heat source in an aquarium. Forgoing a heater leads to no hand control of the water in your tank.

7.Use warm water for water changes.

Warm water can help you raise the temperature of the tank to the level you want to keep without requiring a heater. Of course, this temp is pushed slowly. Raising its temperature at 1 degree per hour is potentially harmful to other fish. You may mix room temperature water with a portion of boiling water but never add boiling water direct to the tank. Keep this in view that if you need extra water for the water change in your tank you need to make an extra water change.

8.Move aquarium to a warmer area of your home/closer to a pond

Setting it to a warmer place gives you several degrees with no hassle. It’s important if you’re choosing the hot summer route to protect your system from algae. It can affect the algae when the light comes in. How can I choose the perfect aquarium setting?

9.Turn up the heater in your house

A good first step for keeping a tank of fish warm without a heater is to increase a temperature in the room in which the aquarium is located to 78 °F (25.5 °C.) It is recommended therefore that nano tanks should not have temperature drop in some nanotubes.

10. Use a hood or canopy

One of the simplest ways to ensure that your Betta water stays warm is to use a hood or canopy on the tank. If you use a lid with your tank, the water will retain warmth better as the heat will not dissipate out through the water’s surface as much as it would without a hood.

11. Use a heating mat

If your Betta fish lives in a fishbowl or small tank you could use a heating mat to warm the water. This would not work with larger tanks.


4 Types of Betta Fish Tank Heaters?

Your aquarium should not have hot water in it if you already own a large, established fish tank with tropical inhabitants. These helpful tips show you how to build a heater-free tank that doesn’t need constant effort to stabilize water temperatures. We will discuss emergencies later! How do emergencies work?

Betta fish need more warmth when being able to prosper. Show some key facts in setting up a betta tank. Check this handy advice for set up betta fish tanks that your betta may need for survival!! Learn the basics of getting the correct heater and setting up your small fishes aquarium in the world of betta tanks.

1.Submersible heater

More submerged heating units will be using molded plastic panels rather than standard glass. These types of heater are normally placed beside the filter and warm up the water before it reaches the tank. They also feature an exceptional system of LED lights which indicate heater status and temperature. The light comes on when the heater is working and goes off when it is left idle or turned off. As it is tipped completely in water that gives the same hotsink more constant energy output while creating a much less expensive and efficient heating solution. This heater is very much stronger because the tank is underwater and preferably tied back to the bottom of the tank.

2.Aquarium heaters and the possible problems that come with them

The temperatures on the two sides of the spectrum are unsuitable for the betta fish. When the tanks are too warm, they are becoming erratic. They swim faster – and if not logically. they continually swim toward the ocean to feel the coldest. Prolonged hot stays in your system can result in death or rapid aging. Another potential danger is that electricity will fail or malfunction the thermometer. All these threats may sound unavoidable but there are a thousand chances of these happening. It is rare when a heater performs its work too well. Sometimes they have an overheating effect which can make them fatal for many reasons. It’s possible.

3.In-line heaters design

This heater takes in one of the uses of the submersible filter and builds its heat-switching system around it. The heater is often connected with it to the filter. It heats the water when it goes back into a tank. It’s more expensive than the typical aquarium heater and is built for aquariums with curious or somewhat aggressive fishes. Having it mounted on the exterior of the tank there will always be the risk of a leak. These heaters are filters manufactured from the factory – supplied with a heater. We want to explore the fish in question and explain just how important the Betta fish appears.

4.Hanging/Immersive heater

Through the glass tubing this heating element infuses heated energy into the boiler system. It’s the most popular type of heater presently and is not particularly powerful. It’s partly submerged inside of tank. Generally in aquariums you need to make a hole to accommodate this heater type. They’re ideal for the basic freshwater arrangement but perform awfully well during the standard saltwater aquarium. However they operate badly. And they’re fantastic at the salt-water setup. The heater style is most perfect for the freshwater aquarium types b.

Bettas need light too

Betta come from rice paddies in Asia. They live in the more tropical climates. It would be beneficial to invest in quality lighting in addition to your heating system. Bettas won’t die by sitting only at night but are substantially less active and more fun. Bettas will not die if they were sitting in darkness. Instead they will be less active in the bright light. You may see Bettas’ other work at Bettas’s website in detail.

Final Thoughts

Betta Fish need more care than the other because it is living in an entirely different environment – water. The water temperature can change easily from high or low which can cause certain negative effects of your fish. This is why managing aquarium temperature is a crucial fact that every aqua-culture owner should consider. No matter how you decide to use your current solution your heater must be the one designed to keep work going at its best performance.
