What is a Media Reactor?

Everyone knows that filtration is one of the most important parts of aquarium maintenance. Poor water quality can have a profound effect on your fish and plants, but maintenance can be difficult.

Filters need to be rinsed every few weeks and the filter itself needs to be replaced every month. The problem with this is that it disrupts a significant portion of the beneficial bacteria colonies that are needed to maintain the nitrogen cycle in the tank.

Most beneficial bacteria live in the substrate in your tank, but filter media is your next favorite place to grow. Rinsing and replacing removes these colonies and takes time to reestablish.

A simple way to avoid this problem is to use a media reactor. A media reactor is an advanced filter with a tube-shaped design. The water moves through an inlet to the bottom of the reactor and then rises through the filter media before returning to the tank.

This upward filtration is much more effective than a typical filter mainly because there is more surface area, which means more contact between the water and the filter itself.


Are Media Reactors Necessary or Not?


If your regular filter seems to work fine, you may not need a media reactor. It all depends on the size of the tank and what it contains.

Sometimes it’s helpful to start with a regular filter and add a media reactor if you feel you need one. You can always start with a standard filter, see how it works, and make the necessary changes in the future with a media reactor.

That said, if you have a large reef tank, media reactors are often worth the investment. Any tank with many needs and a variety of plants, corals and fish can benefit from the increased filtration media reactors provide.


How to Install Media Reactor?

Installation varies slightly from model to model, but there are a few basic things they all have in common.

1. Find a suitable location for the reactor. Some can be placed inside and others can be hung on the back of the tank, but you should place it in an easily accessible place.

2. Make sure the hose is properly connected and the cable is secured in place. Some of these reactors come with tubes, some don’t, but it’s a good idea to have extra tubes on hand regardless of the different installation scenarios.

3. In particular, connect the inlet hose to the pump and place the pump in the tank.

4. Then connect the outlet hose to the reactor. If using a sediment filter, place it at the end of the exhaust tube.

5. Remove the cap and fill it with your preferred filter media. It is very important to follow the manufacturer’s instructions for aquarium size, flow rates and other precautions for each type of medium.

6. Place sponges and strainers on and under other media.

7. Replace the cap and turn the pump on.

Once your reactor is up and running, regular maintenance is important to keep it running efficiently.

Some maintenance services are:

  • Disconnect the power supply and then remove the pump from the tank for cleaning.
  • Rinse the sponges and strain.
  • Only clean the impeller with water. Never use soap or detergent.
  • Use a small brush to clean the inside of the motor housing.
  • Clean the pump, impeller and inlet every three to four weeks.


Factors to consider before choosing the Best Aquarium Media Reactor

Size / Capacity

There are many sizes to choose from, so you should choose the one that is compatible with your tank size. Since most manufacturers design different sizes for different types of tanks, it is easier for you to select.


This is one of the essential parts of an aquarium reactor. Therefore, you should choose a brand that produces a reliable and stable pump. You can also buy a reactor that does not contain a pump, and you can buy the pump separately.

The pump is like a vital organ because it does all the work to bring the water directly into the reaction chamber. So before you buy the pump separately or together with the reactor, you should read the reviews carefully.

In this way you also know the meaning of the pump and you get an idea of ​​which brand you should choose for a stable pump.

Design and quality

As we mentioned before, reactors are a chamber, a pump and some valves that will help you catch the water flow in the chamber or enter the chamber to charge or change the medium.

Therefore, one of the most important features when choosing a suitable aquarium reactor is to see if it is made of quality materials and built with a solid finish.


When it comes to choosing the best aquarium reactor, in addition to its features, you should also consider its cost. However, an essential factor to verify is to see if the desired model includes a pump.

This is because buying an expensive aquarium reactor that does not have a pump will cost you more in the future because you have to buy it separately. But this also does not mean that you should select an overpriced model with a pump.



Sometimes a normal aquarium filter is just not enough to meet the requirements of your aquarium. If so, a media reactor is a quick and easy way to make sure your water is clean and balanced.

There are plenty of great options out there whether you are looking for the best nano medium reactor for a nano tank or something that will fit in your 150 gallon saltwater tank. We hope the information in this guide helps you choose the best option for you.

What is a CO2 Diffuser and What is its Purpose?

Aquarium plants absorb carbon dioxide and give oxygen to the water. That said, they need more carbon dioxide to thrive then what is available in most freshwater aquariums. That’s where a CO2 diffuser comes in.

Since CO2 is a gas, it takes some effort to dissolve it in water. Just bubbling won’t provide the levels that plant life need to thrive. Diffusers work in part by increasing the surface area of water exposed to the gas.

This is generally achieved by passing CO2 through a ceramic disc. This agitates the water and keeps it in contact with the CO2 for longer, allowing it to be absorbed more efficiently.

How to Choose the Best CO2 Diffuser ?

Start with your tank size

Size matters when it comes to CO2 diffusers. A diffuser designed for 10 gallons is not big enough for 55.

The surface of the ceramic disc needs to be large enough to suck up the amount of gas you need for that much water and a smaller diffuser is not designed to handle the higher pressure required for a larger tank.

On the other hand, when using a diffuser designed for a larger tank, lower CO2 pressures may not be able to push the gas through the ceramic disc.

That is why it is important to buy a diffuser that is appropriate for the size of your tank.

Think about the overall quality

With a lot of aquarium equipment, you get what you pay for. CO2 diffusers are no different. Yes, it seems that some diffusers cost a lot more than others when you’re shopping.

A cheaper diffuser could be less efficient and may need to be replaced more regularly. CO2 is not free, so having a diffuser that doesn’t distribute it well through the water is a waste of money.

Sometimes you need to consider usage costs over time rather than just price.

What does the kit include?

Some diffusers come with additional equipment such as U-turns, bubble counters and/or check valves.

If you base much of your choice on price, it’s important to consider whether you need to purchase additional equipment.


Best Place to Put a CO2 Diffuser in Aquarium

Best Aquarium CO2 Diffuser

There are a few things to keep in mind when it comes to fitting a CO2 diffuser for optimal results.

First, it should settle near the bottom of the tank. The longer the bubbles stay in contact with the water, the more it will be absorbed. However, avoid placing it under the ground where the bubbles can be disrupted or blocked.

Avoid placing it between plants. While it may seem like this would be a good place to do it, as it benefits plants in the first place, it can cause unnecessary problems. You could run into the same problem as with the substrate, where bubbles to collect on the plants and mix into larger bubbles that are absorbed less effectively.

Remember that the goal is to circulate the CO2 bubbles as much as possible so they have more time to be absorbed. A good place to place it is under the filter return. That way, the water returning to the tank will push the bubbles down and they can circulate longer.

If you can’t place your diffuser that close to your filter, try placing it in a location where air bubbles are trapped in the flow created by the filter return.

Another thing to remember is that you may need to move the diffuser as plant life begins to grow. Don’t be afraid to adjust to your tank environment as you need to.


How to Install a CO2 Diffuser?

There are many different CO2 diffusers on the market and the installation of the varied models may be unique to each one. But here are some general guidelines:

Follow along the line from the CO2 tank to the aquarium.

The first device after your CO2 tank should be your check valve. This prevents water from flowing back into your CO2 tank when the pressure drops, for example when the power is turned off at night.

The next device should be your bubble counter (if you are using a separate device). This lets you know how fast gas is being fed into the system and allows you to increase/decrease the pressure and amount of CO2 pushed into the aquarium.

Next comes your U-bend. This is important because CO2 hoses can harden over time and bend where it bends over the edge of the tank.

The diffuser is the end of the line. You want to place it as low towards the bottom of the tank as possible. It’s totally fine if it’s just above the gravel. You want the bubbles to spend as much time underwater as possible.


Final Comments

In order for freshwater plants to thrive, most aquariums need extra CO2. By choosing the Best Aquarium CO2 Diffuser, carbon dioxide can be added effectively and your plants will have everything they need to thrive.

Making sure your goldfish tank is sparkling is one of the best ways to ensure they live a healthy life. Keeping the water they live in clean is an easy alternative to paying later with vet visits and expensive medications to help them feel better.

In this article, I’ll show you how to choose your Best goldfish filter and take a look at the best options on the market today so you can choose the Best gold fish filter for your needs.

The 10 Best Filters For Your Goldfish Tanks

Best Gold fish Filter Reviews

1. AquaClear Fish Tank Filter

Best Goldfish Filter

First up is the impressive Aqua Clear filter. This filter is a small but efficient product, ready to use almost straight out of the box. It is ideal for use in tanks that hold 5 to 70 gallons of water.

Despite its small size, this filter has approximately seven times the capacity and volume of comparable filters. This filter also comes fully loaded with many different layers of filter media inside to fully filter your tank every time.

The only problem with this filter is that the level of maintenance required is higher than with other filters. Due to the different layers of filter media, you will have to replace all these filters once every two to three months. That can be time consuming if you’re looking for a filter type to set and forget.

2. Marina Power Filter

Best Goldfish Filter

Third on the list is the Marina Power filter. This filter is the most profitable in this list. It has a slightly below average of only 20 gallons, comes with a multi-step filtration process and has four filter cartridges.

A great feature of the Marina Power filter is an adjustable water flow option, making it perfect for increasing or decreasing the flow depending on the needs of your fish.

This is a good starter filter as it is easy to install and has customization options until you know what works best for your fish.

One thing that goes against the Marina Power Filter is that it has a pretty low maximum gallon capacity.

While it’s good for the price and size, it’s still a little on the low side when it comes to this list. If you have a tank that is larger than 20 gallons, you will definitely want to choose something else.

This filter uses a double-sided dense mesh filter to trap large chunks of debris and debris, also providing the perfect place for beneficial bacteria to grow. Because the filter is located in the tank, it is much quieter than other types of filters.

6. Fluval C Power Filter

Best Goldfish Filter

The Fluval C Power Filter Clip-on Energy Filter holds up to 70 gallons, but the recommended size is for 40 gallon aquariums. Power filters are generally designed for smaller filters, so the fact that it has a throughput of 264 gallons per hour is pretty impressive.

Its relatively small size, measuring 9 long, 6.5 wide and 8.5 high, makes it easy to fit in your tank without any problem with the space available.

Now, for the technical aspects, the filter has an innovative five-stage filtration: two mechanical, two biological and one chemical for crystal clear water.

The first two mechanical stages comprise a double layer of foam and polyester with a large surface area, which can be easily removed for quick cleaning. That layer works to trap large particles and fine debris.

It also has an oversized BIO wheel filtration system, meaning you can rest assured that the water in your tank is thoroughly cleaned and treated with every use.

A common problem that users encounter with this filter is that it is also a bit noisy. Usually this isn’t a problem with these types of filters, so it’s quite unusual to see this in this one.

The self-priming pump has adjustable flow using the rotary knob on the front, which also allows you to easily control the inlet flow.
Another point is that an adjustable spirit level on the bottom of the filter allows you to provide a suitable environment for your fish by controlling water movement and oxygenation.

When the water flow is stopped, most filters usually deal with some kind of problem where debris falls back into the filter. This filter solved this problem by designing the basket with raised slots that trap debris.

Still, the filter media tends to clog over time, eventually preventing water from passing through. When this happens in the Tidal 75, the water is routed around the filter and back into the aquarium. This water then pushes a maintenance monitor on top of the filter, letting the aquarium owner know it’s time to clean the filter media.

The bottom-up flow, through which water is pumped through the bottom of the basket and pushed out, ensures that the water meets all the filter media. This type of flow sets this high-performance filter apart from other hanging filters with a back-to-front flow. When using it, make sure that the water cannot circulate or bypass the filter media.

With a capacity of up to 75 gallons, it features an innovative design, with vent slots in the filter cover and vent slots in the exhaust stream that maximize gas exchange during filtration, ensuring fully oxygenated water is returned to the tank.

Does a Goldfish Tank Need a Filter?

Is it important to purchase a filter for your tank?

Yes, because changing the water every now and then can only do so much, but a filter that constantly turns the water on does so much more. Filters are an affordable and easy way to keep water moving and prevent bacteria from building up in your aquarium.

In addition to preventing water from stagnating, an aquarium filter also removes dirt and food debris from the aquarium. If these things were simply left in the water, they would quickly become a buffet table for harmful bacteria.

Not only that, but this type of waste also increases the ammonia content in the water. These rising levels of harmful ammonia can cause a host of problems for fish, including skin burns, swim bladder problems and general malaise.

Finding a good filter can be difficult, but it is an effort you must make to help your fish live happy and healthy lives.


How to Choose a Filter for Your Goldfish Tank?

Now that you understand a little about the different types of Best Goldfish Filter tank, you can turn your attention to finding a filter that meets your specific needs.

There are a few different things to consider when buying the right filter.

Goldfish Tank Size

The size of your aquarium is one of the first things to consider before purchasing a filter. A goldfish tank is measured by how many gallons of water it can hold at one time.

This amount is important when buying a filter because if the filter does not have a good maximum flow rate, your aquarium will not be cleaned properly and you risk making your fish sick. Figuring out how many gallons of water are in your tank is the first step in buying the right filter.

Water flow rate

The next thing to pay attention to is the flow rate of the water in your tank.

This is related to the size of your tank, so if you have a tank with 30 gallons of water, you should get a filter that can dump about five times that amount, or 150 gallons, in an hour.

Good water flow will keep your tank from cleaning too fast or too slow.

Types of Aquarium Filters for Goldfish

There are many different types of aquarium filters that you can try, such as sponge filters, power filters, and canister filters.

A sponge filter is usually used in breeding tanks and is powered by an air pump that pushes water through a spongy material. This also allows beneficial bacteria to take root and promote the health of the water.

An energy filter uses electricity to draw water through the different types of filter cartridges. These types of filters are also called HOB or trailing filters because they usually hang over the edge of your aquarium.

Finally, there is the bus filter. Canister filters use electricity and use a “water rod” to spread the stream of clean water along the length of the rod. This type of filtration is good for planted and saltwater aquariums.

Filtration technology system

There are three main types of filtration that occur in a healthy aquarium. Mechanical filtration is when water is forced into a filter designed to trap debris during transfer.

Chemical filtration refers to when toxic chemicals pass through a filter. This filter is specially designed to attract and remove these molecules from the water.

Finally, biological filtration takes place when different bacteria dissolve with the help of good bacteria. A biological filter promotes the growth of good bacteria and stops the appearance of harmful species.

All three filtration methods are necessary for a healthy aquarium, so a filter with equipment for all three is the best option.


Which Filter Is Best For Your Goldfish?

That is a difficult question to answer. In the end it all comes down to two options depending on the size of your aquarium.

If your aquarium is 100 gallons or more, the Fluval FX6 High Performance Aquarium Canister Filter is your best option. With an astonishing flow rate of 925 GPH it is more than sure to do the trick. Customizable features make it easy and hassle-free to use.

For smaller aquariums, exactly 55 gallons or less, the Seachem Tidal 75 Aquarium Filter is best. It has an internal motor that eliminates both noise and the need to fill the filter. Overall, it is a powerful filter with good water flow that provides excellent filtration.


Can Goldfish Live and Survive Without a Filter?

Goldfish are surprisingly hardy and will survive in an aquarium without a filter. However, fish can only live in poor water conditions for a short time.

The quality of the environment has a major influence on the lifespan of a goldfish. Healthy goldfish have a lifespan of 15 to 20 years, while stressed goldfish only live two to three years.

Goldfish are characterized by being dirty and messy, requiring a filter. Novice aquarists often think that water changes are enough to keep the container clean, but it’s impossible to keep up with goldfish waste production.

If you see your pet gasping for air on the surface, the water conditions in their aquarium are harmful to them and the oxygen level is insufficient.



After all this information, you may feel overwhelmed at the idea of purchasing a best goldfish filter for your tank. The good news is that you can enlist the help of the experts at your local aquarium supply store to find out the details you may be confused about.

Once you’ve found your perfect filter, you can continue to use the same make and model and keep your fish happy.

Benefits of CO2 Systems in Planted Aquariums

For a planted aquarium to thrive, the tank needs to be supplied with two things: light and carbon dioxide.

Tanks that operate in closed rooms can mean CO2 supplies can be quickly exhausted and your plants won’t be able to photosynthesize properly. Plants may wilt or eventually die, and oxygen that they produce as a result of photosynthesis will no longer reach your fish and other live animals in the tank.

Installing a CO2 system into your planted aquarium means you’re providing a consistent and reliable source of CO2 into the environment. Allowing your plants to complete their cycle of photosynthesis and live longer and healthier. Plants can then work to keep your tank’s natural environment healthy and be an active source of oxygen for your live pets.


How Does an Aquarium CO2 System Work?

Best CO2 System for Planted Aquarium

There are three main types of CO2 systems that can be operated with your aquariums; manual, semi-automatic and automatic system.

Regardless of the system, most of the features are the same and the main purpose is to replenish the carbon dioxide supply in the water.

Manual CO2 systems operate based on fermentation products. CO2 is produced as a by-product of yeast fermentation, which is stored in a separate bottle from the generator. The bottle is connected to your tank and the CO2 by-product is released through a diffuser or powerhead.

This type of system works best with smaller tanks, as they require some maintenance, but are usually the cheaper option compared to the other types of systems.

Semi-automatic CO2 systems operate with a specific configuration to transport CO2. The gas comes through a pipe connected to the CO2 tank and the water. The system automatically opens the CO2 valve based on a timer, making it semi-automatic.

Medium-size tanks are ideal for these systems, as maintenance is less prominent. You also don’t have to spend time to manually check and add CO2 to the tank.

Automatic CO2 systems are similar to semi-automatic, except that nothing more needs to be done after installation. The system can automatically measure the amount of CO2 in the water and adjust the levels accordingly.

This is a more accurate choice for your tank and is ideal for larger aquariums that require more CO2 for plants.


How to Set Up a CO2 System for a Planted Tank?

As with the methods of transferring CO2, the actual setup of your CO2 system depends on the type you buy. If you choose a DIY system, more time is required to set up compared to an automatic one.

For DIY or manual systems, you start by creating a liquid that can ferment, like grape juice. You then connect the fermentation bottle to a valve that leads the carbon dioxide to your tank. Once everything’s been installed, you can manually open the valve occasionally to let CO2 into the tank.

For both semi- and fully automated CO2 systems, you just need to connect the CO2 tank to your tank. This is done with tubing and valves. The specifics for your tank are in the instructions, but the main idea is to make a connection.

Once you establish the connection, all you have to do is monitor the CO2 levels in the water.


FAQS About CO2 In Planted Tanks

  • Is CO2 harmful to fish?

CO2 when used in moderation is not harmful to your live fish and pets. However, if your tank is saturated with high levels of CO2 for a long period of time, it could cause a danger to your fish.

  • Do planted tanks need CO2?

All plants need CO2 to complete photosynthesis. In closed tanks, your plants may be able to get small amounts of CO2, but it may be detrimental to their health in the long run. Added CO2 injections can make your plants grow faster, while also helping their color, health and shape.

  • Can a plant benefit from CO2 in low light?

Absolutely, CO2 is such a critical health component for aquarium plants. Plants in low light + low power + CO2 are actually a great way to grow more slowly but in a healthy way in it’s aquatic environment.


Final Thoughts

Finding the Best CO2 System for Planted Aquariums is beneficial on so many levels, from helping your plants flourish and thrive, to providing your fish and other live animals with stable sources of oxygen. CO2 systems can keep the levels of CO2 in your tank stable with little to no maintenance on your behalf, depending on what style of system you choose.

How to Use Aquarium Magnet Cleaner?

The internal scrubber is the one that goes into the tank. It has a textured surface which is generally made of a material in the form of a Velcro fastener to remove algae from the glass in the tank. Sometimes it is also equipped with a scraper for things that are more difficult to clean.

The outer handle is attached to the scrubber with a powerful magnet. To attach to the tank, insert the internal scrubber so that the pad is against the inside of the glass. Then place the outer handle directly in front of the scrubber so that the magnets are stuck together with the glass panel in the middle.

Then when you remove the handle from the tank, the internal scrubber follows, which moves against the inside of the tank and removes algae.

Actually, this filter uses three different media for filtration. At the bottom of the bowl is a foam insert, which removes debris and provides an ideal surface for beneficial bacteria to thrive and keep the water colonized. The middle layer is activated carbon which absorbs the impurities in the water.

The top layer consists of BioMax, designed with a pore system that provides a perfect home for beneficial bacteria. These layers together provide six times as much media as other filters.

What is a Power Filter?

A power filter is a hanging model that uses a pump to circulate the aquarium water through the system and then return it to the tank.

It uses a riser to pull the water out of the tank and into a filter chamber where it is pushed through various filter media. Filtration stages vary by model.

However, there are usually mechanical, chemical and biological filters that remove toxins and debris from your aquarium.


What is the Best Aquarium Power Filter?

The AquaClear Power Filter is the best aquarium power filter we’ve tested. It is very versatile and comes in 5 different sizes, so it will fit in almost any tank. This allows you to adjust the flow in case you have plants or fish that require a lower flow.

The three different filter media used in this filter are really effective. The foam insert removes large debris, the carbon middle layer absorbs invisible impurities and the BioMax filter provides the perfect home for all the good bacteria you need to keep your tank nitrate and ammonia free.

What makes this the best potency filter is the way it is designed to maintain natural bacterial colonies. With most filter systems, replacing the cartridges or cleaning the filters removes good bacteria and can take a while to grow back. During this time, the environment in the aquarium will be stressed, which will affect your fish.

Because it maintains these colonies, the AquaClear Energy Filter is a bit ahead of the pack.


How Does a Power Filter Work?

A power filter hangs on the back or side of your aquarium. While each model looks a little different, they all basically work the same way.

A riser sits in the water that the pump uses to draw the water out of the tank. The water then enters a filter chamber where it is pushed through different types of filter media. Filtration stages vary by model. Some offer up to 5 different stages. In general, however, mechanical, chemical and biological filters will always be present.

Mechanical filters remove larger particles and dirt particles. Chemical filters remove impurities, odors or cloudiness from the water. Biological filters allow good bacteria to thrive so they can remove nitrates and ammonia from the water.

These good bacteria are essential for the health of the aquarium. It is beneficial for water, plants and fish and does not change the appearance of the aquarium. The water will remain clear and the plants and animals that live in it will thrive.


How to install an aquarium power filter?

Once you’ve got a power filter for your aquarium, the next step is to install the device: FYI, the power filter is usually placed on the back or side of the aquarium. But before sharing the steps with you, it is important to indicate which (items) you need to consider in the package. Items must contain:

  • A filter chamber in which biological, chemical and mechanical means must be incorporated.
  • Lift tube extension
  • Filter pump and cord
  • Cartridge and its holder
  • power wire

Now to the installation itself:

  • Connect the pump to the filter chamber and make sure it is firmly in place.
  • Attach the lift tube to the pump.
  • Now take out the cartridge and rinse with water to remove dust. The cartridge must then be placed in the cartridge holder and placed in the chamber.
  • Now you can place the assembled power filter in your aquarium using the suction cup or other fasteners from the manufacturer.
  • After that, you need to fill the aquarium with water, making sure that the [water] level is close enough for the filter to absorb the water easily.
  • After completing the above steps, you can plug in the power cord to turn on the aquarium power filter.

How to Clean Aquarium Power Filter?

The specific way of cleaning and maintenance depends on the model and brand. You should be able to find detailed instructions in the manual that came with your filter.

Regardless of the type of filter media you use, you must clean it by rinsing it to remove any accumulated residue. Ultimately, you will need to replace any filter media.

If your filter contains a sponge, you should be able to rinse it in the aquarium water if necessary. Only when they start to show signs of defect or wear should they be replaced.

Charcoal media should be changed regularly to keep the water toxin free. If you need to add medication to the water to treat your fish, remember to remove the carbon filter first.

Leaving it will filter all the medication, meaning the tank will not be treated and the filter will need to be replaced much sooner.

You should also clean the hoses and pump from time to time, as they cannot function properly if too much dirt builds up.


Final Thoughts 

Finding the best aquarium power filter will keep your aquarium water healthy and clear. They provide the essential mechanical, chemical and biological filtration your plants and fish need to thrive.

Bubble boxes, underwater rivers, and air stones not only look attractive, but are often an essential addition to densely populated aquariums.

When installing bubble makers in your aquarium, make sure they are not too strong for your fish. If the water flow is too high, the fish will have a hard time swimming and despair, which often leads to disease.

A high flow of water can be compensated by adding dense objects such as floating wood.

The best aquarium decorations are those that look natural, even though they are artificial. Like this ornament, it looks like a real aquatic plant that you can’t even say is made of plastic. It is exciting to buy something good for a very reasonable price.

You will find that the decoration of this tank is a practical element, since it makes the aquarium look more alive and does not endanger the health of your fish. This does a great job when it comes to breaking lines of sight in a larger aquarium. Surprisingly, it would be confusing to determine if it is real due to its natural look and style or not.

The only things that give this tank decor some negative comments are its pale stem, which doesn’t mix well with the rest of the decor, and some leaves warp.

If you prefer to avoid natural wood because you fear it will color the water, this resin float is an excellent alternative.

It has realistic looking artificial plants along the top and some fun nooks for your fish to explore.

The safe and non-toxic resin is ecological and does not change the chemistry of the water. It’s great in an aquarium, but it would also be a great addition to a reptile tank.

23. Nature’s Ocean Coral Base Rocks for Aquarium

While it is obviously true that these cool aquarium decorations are overpriced, there is no denying that they offer absolute value for money. You could help make the tank look like a natural, oceanic environment that your pet fish will thank you for.

In addition to aquariums, these products are great for many different purposes as they can also be used to grow live corals, develop live stones, and the perfect choice for growing corals. They are also of the highest quality in terms of habitat and have no negative effect on your tank cycle. Note that they must be soaked in deep water to effectively prevent leaks.

These coral beds need to be rinsed desperately as they are laden with sand and dust that must be removed completely to avoid problems once added to the reefs. And it’s expensive, which could surely hurt your budget. These are some of the minor problems that should be considered before making a final purchase decision.

24. Bonsai Driftwood Aquarium Tree

This floating bonsai wood tree is made from natural wood that has been transformed into a beautiful work of art. This wood is safe for fish and shrimp and nice when mixed with stones, moss, and air plants.

Since this wood contains natural tannic acid, it conditions the water and can lower the pH of your tank.

For best results, the wood should be boiled for 20 minutes to sterilize it before adding it to the tank.

Two factors to consider are the various rough spots on the inside and outside of the tree trunk. The inner part of the tree trunk has very sharp edges and bumps that must be sanded to smooth them out.

How to choose decorations for an aquarium?

The good news is that there is no right or wrong way to decorate an aquarium. As long as you use high-quality materials that won’t change the water or harm your fish, anything is possible.

When choosing decorations, you must first decide how the overall image should look, and this can actually be very difficult because there are so many options.

Here are some things to think about when deciding which direction to go.

Natural vs Not Natural

The first thing to decide is whether you want a purely natural theme or something fantastic and fun.

What do you like more, driftwood and rocks or magnificent castles and plants that glow in the dark?

Of course, there are no strict rules for decorating aquariums, so you can mix everything if you want. However, choosing whether to stick with a natural underwater scene or create something completely different is a good place to start.

Color scheme

There are two ways of thinking about color.

First, ask yourself if you want to follow a color scheme. Do you prefer a natural interior with lots of browns and greens? Or would you also like to add some bright colors?

Then ask yourself what kind of fish you will keep in the aquarium. If you have a lot of bright and colorful fish, the best way to highlight them is to use a white substrate with natural green plants. If your fish are lighter in color, a dark substrate and dark decorations can really help them stand out.


Live plants in your aquarium have many advantages, but artificial plants are much easier. There is no maintenance at all and some of them look so realistic that you can’t tell the difference.

If you choose live plants, there are many great natural decorations that can help them take root and establish themselves effectively. Adding driftwood can really help.

Design or how to make it look good

You can honestly set up your tank the way you want, but there are some design rules that need to be followed to get a more natural look.

First, choose a primary focus. It is a good idea to choose something with some holes or corners and angles to give the fish a place to hide and play.

Next, consider the height of your decorations. So think about it. Different types of fish prefer different parts of the tank. They have the best swimmers, the bottom residents and those who hang out somewhere in between.

Aquarium owners often spend a lot of time placing plants, stones, wood, or castles at the bottom of the tank, but don’t think much about height.

You must decorate the three areas where the fish like to walk. This may mean that some tall plants reach the top of the tank or a large piece of floating wood that covers the tank from the bottom up. Just be sure to add some height.

Another thing to consider is how many decorations to include. You don’t want to go overboard because your fish still need room to swim. However, the tank should not look too tight.

A good rule of thumb is to fill about 50% of the tank with decoration to ensure there is still ample room for fish to swim. Spread things out in even groups so there is a place for fish who like open spaces and areas where shy fish can hide when they need it.



When it comes to decorating your aquarium, there are no right or wrong answers. As long as you use quality products that do not adversely affect water, you can choose any decoration.

In a way, make the decision to do what you want more difficult. Take a look at the decorations we recommend and make suggestions on how to choose the one that’s right for you. Both you and your fish are the way to a happy and beautiful aquarium.

Top 10 [2023] Best Aquarium Test Kits Help Monitor Water Quality

Whether your aquarium is fresh water with a handful of fish or salt water with blooming coral … Keeping your water healthy and balanced is the only way your aquarium environment can thrive.

To ensure that you create the best possible environment, it is important to find the best aquarium test kit for your aquarium needs. The best aquarium test kits are invaluable tools that every aquarist should have. This allows you to accurately measure the condition of your tank and adjust it if necessary.

Without this crucial information, you would not be able to know whether or not your tank is healthy. Meanwhile, your fish may be in pain! All of the most experienced aquarists we know invest in the best water testing kits they can get. If you’d like to follow suit, read this guide to see our recommendations.


What to test in the aquarium water?

Freshwater aquariums

The pH of the water is important in a freshwater tank, because too high or too low a pH can stress the fish. The pH scale ranges from acidic to alkaline and is measured from 0 to 14.

Most fish prefer something neutral that is between 6.6 and 7.8 in the center of the scale. You may need to make adjustments based on what your test results show and the type of fish you have. Some like a more acidic environment than others.

It is also important to know how much ammonia you have, as too much ammonia can kill fish. Ammonia comes from the breakdown of waste and uneaten food. For a healthy tank, the ammonia should always be zero.

It’s also important to check for nitrites and nitrates. Nitrites are the result of beneficial bacteria in the tank that break down ammonia. Nitrates are the result of the breakdown of nitrites. Nitrites are not as harmful as ammonia, but they can still cause a problem if they get too high.

Nitrates are the final stage of what is known as the nitrogen cycle. They are not really harmful and can be seen as a sign that bacteria in your tank are doing their job of breaking down ammonia and nitrites.

Hardness measures dissolved substances in water, in particular calcium and magnesium. Soft water can be a problem because the pH can drop if it is too soft. Alkalinity is an indicator of stability and how well water can maintain its pH. Too low and the pH fluctuates easily and can harm your fish and plants.


Seawater aquariums

For salt water tanks, check everything you would for fresh water, as well as salinity and chlorine.

Reef ranges

For reef tanks, check the same parameters as for salt water tanks, as well as phosphate, calcium and magnesium.

Calcium and magnesium are important for healthy coral growth and too much phosphate can lead to algae growth.

Planted aquariums

Test the same things you would for fresh water, as well as general water hardness (GH) and alkalinity (KH), which are essential for plant growth.


The Best Water Test Kits for Freshwater, Saltwater & Reef Tanks

You need to make sure you are using the correct type of sealant for the type of water your aquarium has. Salt water test kits do not work with fresh water and vice versa.


Aquarium Test Kit Reviews

1. API Freshwater Master Test Kit

To monitor the health of your freshwater aquarium, it is important to remember that many potential problems are invisible. The API Freshwater Master Test Kit should be used once a week and when problems arise.

This freshwater test kit comes with everything you need to test the most important elements in your freshwater aquarium: pH, high pH, ​​ammonia, nitrite and nitrate. These things greatly affect the life of your freshwater fish.

You get an instruction booklet, seven test solution vials, four test tubes, a test tube rack, a holder and color charts that are analyzed with the computer for accurate comparison and laminated so that they can tolerate getting wet during the test.

This kit is a great value as it can run over 800 full tests, meaning it will last a long time.

This kit is accurate enough to determine the basic levels and overall health of your aquarium. It can tell you what things are there that shouldn’t be and give you a rough measurement. This kit is usually sufficient to monitor and maintain a simple tank.

2. API Reef Master Test Kit

Each type of aquarium requires different tests and the API Reef Master Test Kit gives you the tools you need to verify the safety of the water for your reef inhabitants.

You can perform more than 500 tests with this kit. It includes seven test reagent bottles, four glass test tubes, an instruction booklet and troubleshooting information for any problems you discover, and two laminated color charts so you can compare your result with accurate, computer-calibrated measurements.

This kit tests for calcium, carbonate hardness (KH), phosphate and nitrate, all important for the balance of your aquarium reef. Use it weekly to reveal invisible problems that your reef inhabitants may be facing or when problems arise.

This is a good kit if you are looking for something for general maintenance and you want to keep your water healthy and your plants and animals happy. It will give you a general reading of the levels of different elements in the water, but it won’t be able to give you really accurate readings.

3. API Individual Aquarium Water Test Kit

These individual API test kits provide you with everything you need to test a specific level in your tank. Choose from kits for ammonia, copper, GH and KH, pH, nitrite and phosphate. This is not an all-in-one set – each set monitors a different water parameter.

While all-in-one kits have advantages, using a kit that proves one thing can be very helpful. For example, if you regularly run tests with an all-in-one kit and find that the pH is not right, a single test kit will only allow you to recheck the pH daily and get a more accurate reading.

Each kit includes two bottles of test solution, a glass test tube with snap-on cap and color charts to accurately interpret fresh and salt water tank results. It is easy to use and will give you results in seconds.

The phosphate kit is especially useful for planted tanks and if you have a problem with copper or can’t control the pH these kits are super accurate and you can focus on one parameter at a time.

4. API Freshwater and Saltwater Aquarium Test Strips

These API strips are easy to use and give accurate results for five different parameters: water hardness, pH, nitrite, nitrate and pH.

Dip the strip in the aquarium water and rotate it twice. You can read the results directly by comparing the strip with the supplied table.

It also includes some troubleshooting instructions so you can find out what to do if something with the test doesn’t work. They even go into a little bit about which fish species prefer a different pH and other more specific information than a simple result.

These strips can be used for both fresh and salt water. They come in packs of four, 25 or 100 pieces. They recommend using the strips on a weekly basis, so sets of 25 or 100 strips are ideal.

If you’re setting up just one tank and want to monitor your cycling progress so you know when to safely add fish, the four-strip kit can help, but larger amounts are definitely a better value in the long run.

5. VANSFUL Smart Water Test Kit


Vansful test strips test 10 different water parameters: pH, Alkalinity, Iron, Copper, Total Hardness, Lead, Fluoride, Free Chlorine, Nitrate and Nitrite. Immerse the strip in the water and wait 45 to 60 seconds for the results to be read.

This is a great option for a reef tank or a heavily planted tank, something you’d like to know more about than just the basics. If you have a fragile tank that requires a lot of care and maintenance, these strips will give you a lot of information.

The side of the bottle features an easy-to-read graph, each marked with the normal range, so you can immediately interpret the results. There are also 500 strips in the package, so you don’t have to worry about getting more strips for a while.

While this kit includes so many strips, the bottle is a good size and easy to transport, so it’s not difficult to take everything in good light to get the results accurately. If you have multiple tanks, it is also easy to switch from one to the other.

6. Lifegard Aquatics 5 Way Test Strip

This simple test kit from Lifegard Aquatics checks five different parameters: nitrite, nitrate, hardness, pH and alkalinity. They are great for freshwater and saltwater aquariums, but can also be used to control pond water.

There are 25 strips in this kit and they test for alkalinity, water hardness, pH, nitrate and nitrite. The bottle is lined to keep moisture out and has an easy to open flip cap. With a graph on the side you can quickly read the results.

This is a good kit if you are looking for something a little simpler. Just test the necessary parameters and it is a good choice for a simple fresh water tank.

7. API GH & KH Liquid Test Kit (Top Pick)

  • General hardness (GH)
  • Carbonate hardness (KH)

With the API GH & KH Liquid Test Kit you can check the carbonate and general hardness of your tank water.

These work a bit differently from other tests. You put the test solution into the water sample drop by drop, cover and turn the sample to mix it evenly.

Count the drops as you go until the sample turns a specific color. Each drop represents a degree of hardness (it works the same for general hardness or carbonate). So if it takes 3 drops to get the right color, the water has a hardness of 3 degrees.

These tests are very accurate and are the same tests that scientists use to test the hardness of water in the field.

One drawback is that it can be difficult to see the color change. If you are having trouble, look through the open top of the test tube instead of from the side.

It also bothers me that I have to buy these tests separately from the Master Test Kit I think the logic is that many aquarists don’t even pay attention to their GH and KH.

8. Tetra EasyStrips

  • Chlorine
  • Total ammonia: ammonia (NH4 +) and ammonia (NH3)
  • Nitrite
  • Nitrate
  • General hardness (GH)
  • Carbonate hardness (KH)
  • pH

Okay, I have to admit, I’m generally not a huge fan of most Tetra products, but I think their test strips are pretty good.

They are sold in small batches, which should help prevent spoilage.

I ran the numbers in these tests. They cost about $ 0.68 per test, compared to an average of $ 0.14 per test for liquid kits. That’s about 4.8 times the cost of liquid testing.

This is useful because you are running seven tests at a time. And I’ve found these are quite easy to read when you compare them to the chart.

Still, I recommend that you use common sense when using these (and any other brand of test strips). If something says 0 and it really doesn’t make sense, use a different strip and / or a liquid test kit so you can compare the results.

I also don’t like the fact that the bottle doesn’t tell you whether it’s testing total chlorine or just free chlorine.

There is a big difference.

Total chlorine indicates how much free chlorine (regular chlorine) and combined chlorine (chloramine) is in the water. A test that registers only free chlorine will not detect chloramine in the water.

So you might think that tap water is safe without dechlorination when it actually contains a deadly substance that can kill your fish.

Since the manufacturer doesn’t specify what kind of test it is, they don’t know if chloramine will show up.

Play it safe, add dechlorinator.

9. Life2O Ultimate Aquarium Water Test Strips

  • Free chlorine
  • Nitrite
  • Nitrate
  • General hardness (GH)
  • Carbonate hardness (KH)
  • pH
  • Total alkalinity
  • Mercury
  • Send
  • Iron
  • Manganese
  • Buyer
  • Zinc
  • Fluoride

I like that this allows you to test for heavy metals, something that can sometimes contaminate municipal drinking supplies. Fish can be even more sensitive to this than humans, so it is better to know if they are present in tap water.

Using a reverse osmosis (RO) unit to purify some of your replacement water would also be a great way to check how efficiently your membrane is working.

Reverse osmosis membranes wear down over time. So if you used a strip in your RO water periodically, the tests that started showing a positive result would let you know if you need to replace the membrane in your unit.

At $ 0.30 per test, these are quite inexpensive compared to other test strips.

A disadvantage is that these strips show free chlorine, but not total chlorine. This means that they will only show results if your water supply uses pure chlorine.

But nowadays more and more water companies have switched to chloramine, which is chlorine that is bound to ammonia. Chloramine does not appear in a free chlorine test. This could lead some aquarists to believe that their water is safe for fish when it actually contains a deadly substance.

My other complaint is that these strips test for 14 different substances, but ammonia is not one of them! Since ammonia can be an assassin in your tank, it is best to skip something like fluoride (non-toxic to fish) and replace it with ammonia (very toxic to fish).

10. Sera Aqua-Test Box (+Cl)

  • High range PH
  • Low range PH
  • General hardness (GH)
  • Carbonate hardness (KH)
  • Total ammonia: ammonia (NH4 +) and ammonia (NH3)
  • Nitrite
  • Nitrate
  • Phosphate
  • Iron
  • Chlorine

The Sera Aqua-Test Box (+ Cl) is an excellent complete test kit that includes basic water parameters plus a few extras, such as phosphate and iron, which are great for planted tanks.

You can store everything neatly in the carrying case, so you don’t constantly lose parts or have to keep each individual test in a cardboard box.

Test tubes are much larger than many of the standard liquid tests, which makes them easier to use as you don’t have to constantly worry about them falling out.

I was very impressed with the color comparison chart as it is much larger than most tests, making it easier to read.

Instructions can be difficult, especially for beginners, as English instructions alternate with German and other languages. Some users complain that the printout is small and tight, it’s not something you can scan quickly and get what you need for testing.

It also only tests for total ammonia, there is no separate test that allows you to compare total ammonia (ammonia and ammonia) with free ammonia (ammonia only).

And it doesn’t specify whether it tests for total chlorine or just free chlorine. This is an important distinction, as total chlorine will show you chlorine and chloramine on a regular basis, and free chlorine testing will only register regular chlorine.

How do you use an aquarium test kit?

While there are differences from kit to kit and between different brands, all Best Aquarium Test Kits are used on the same base.

First, collect your materials: test solutions, color chart to compare results, test tubes, syringes, or other methods of obtaining a water sample from your aquarium. Everything you need is normally included in the kit.

Next, it is a good idea to label each tube with what is being tested. For example, write “pH” on one tube and “nitrate” on the other to avoid confusion. Repeat for every part and pipe. If you don’t want to write on the tube, label the holder to see what you put in each tube. This is the only way to make sure you read the results accurately.

Once everything is labeled, fill each test tube with the amount of water recommended in your kit instructions. 5 ml is a common amount, but your kit may vary. Add one of the solutions to each test tube. The number of drops will also vary, so read the specific instructions for your kit. Depending on what you are testing, the drops can vary between three and ten drops.

Prepare one test tube at a time. Add the correct number of drops, replace the cap and shake the tube to mix. Then move on to the next tube, add the correct number of drops, replace the cap and shake. Do this until the pipe tests another part.

Each solution will develop and the water will change color depending on the amount of what is being tested in the water. Compare the result with the table provided with your kit. If everything is within an acceptable range, that’s fine until next week. If anything needs to be adjusted, take appropriate action and retest later in the day.

As mentioned above, the kit you choose may vary slightly so read the instructions carefully. This is a simple explanation, but there are some kits that are a bit more complicated than the ones described here.

Frequently asked questions about aquarium filter media

1. How to place the aquarium filter media?

There is a science to putting medium in an aquarium filter, but when you think about it, it makes perfect sense.

How to Stack Aquarium Filter Media

The first thing to filter the water is a mechanical means. This removes large particles and debris and stops them before they reach the other layers of the filter. It also makes it easier for you to clean the filter as everything has to collect on the surface.

If you are using something that has a dual purpose, you should go next. Ceramic rings are a good example of a dual surface medium, as they retain large particles and provide a home for bacterial colonies to grow. They act as mechanical and biological filtration, which is why they are known as “dual purpose”.

The following is the biological environment. It is important that this layer does not become clogged. If the water flow stops, the bacteria will not get enough oxygen and the colonies will die. If you put in the mechanical filtration first, it shouldn’t be a problem.

The bottom layer must be a chemical medium. It removes any toxins that are left after the water goes through biological filtration, so it makes sense that this is the final stage. If placed in front of biological media, there is a risk that not enough impurities will remain for bacteria to thrive. By placing these last, each filter layer can do its job more effectively.

2. How often should the filter media in the aquarium be cleaned?

Maintaining the filter is the most important thing you can do to maintain a healthy aquarium. If they don’t work properly, toxic levels of ammonia and nitrate will quickly build up in the water, potentially killing fish.

Cleaning the filter media is essential for it to work properly. A good rule of thumb is that the more fish you have in an aquarium, the more often it needs to be cleaned. Larger tanks may take a little longer between cleanings, but smaller tanks require regular maintenance.

Test your water weekly with test strips. These will tell you the levels of ammonia, nitrate and pH, among other things. If you see a change in the results, it is time to clean your filter. If you notice that the flow rate is slowing down, it is probably because the filter media is blocked, which also means it is time to clean.

It’s difficult to set a clear time frame for when to clean as this varies from tank to tank, but on average once a month is a safe bet. Again, depending on the results of the strip test, you may need to do it more or less often.

Mechanical media, bio balls and ceramic rings should never be cleaned with tap water as chlorine can damage them. The best way to clean these things is to fill a bucket with water from the tank and rinse the medium well into the bucket.

This prevents the death of beneficial bacteria and prevents possible contaminants from entering the water. The easiest time to clean is when you change the water as you are already removing water from the tank. There are some exceptions as some media, such as charcoal, cannot be cleaned.

3. How often should I change the filter media in the aquarium?

The carbon filter media should be changed every 3 weeks to keep it functioning properly. Carbon cannot be cleaned because the chemical properties required for filtration slowly deteriorate over time. It’s not as easy as rubbing it well.

As for the other types of media, it depends.

Mechanical means can be used until they essentially fall apart. Since this medium’s job is to filter out large chunks of debris, it will continue to work even if not in perfect condition. Check your filter every day to make sure it is running smoothly. When you see particles going that should have been mechanically stopped, it’s time to replace them with new ones.

If you are using ceramic bio balls or rings, you should only replace about â…“ at a time and only if they fall apart. Remember that colonies of beneficial bacteria grow on this medium, so replacing them all at once will kill any good colonies that take time to grow back.



All of the filters we’ve reviewed are great, but it’s hard to pick the best one because they all work in different ways. If you are just starting out and need something to meet all your needs, get started with CNZ Aquarium Filter Media Kits.
