That’s why you need a Chiller to bring the aquarium temperature within the correct range for your fish species.

So what are the best aquarium Chillers?

Anyone who has never used an aquarium Chiller would have this question in mind. Well, don’t let that worry you that much as we can see below some of the best coolers you can get for your tank.

The summer of 69 may be the best days in Bryan Adam’s life, but not in general for people like us. Summer is generally a difficult time to get through if you live in warm areas such as the southern United States or South Asian countries such as India, Bangladesh and Pakistan. And when you think of those fish, aquatic plants and corals that live in hot water all day, you will realize that summer is actually a poker-faced nightmare. An aquarium in a warm climate may require an aquarium Chiller to maintain stable temperatures.

Keep in mind that aquariums should under no circumstances exceed 83 ° F. At a water temperature of 83 ° F or higher, the oxygen level in the aquarium water begins to decrease and this leads to a stressful competitive situation for fish and inmates to oxygenate. to gain. Fear this can lead to the death of your aquarium inhabitants.

For optimal health of your fish and other aquarium species, it is recommended that you keep them within an acceptable water temperature range. For example, tropical fish and marine aquarium fish have an acceptable range of 72 ° to 80 ° F (optimal is 78 ° F), Fancy Tail Goldfish have an acceptable range of 65 ° to 72 ° F, and Common Goldfish have an acceptable range. from 65º to 68º F.

If you will be away from home all day, which of course you do for office reasons, classes or just to run errands, DO NOT keep your aquariums in a place that is in direct contact with the sun. This will lead to more algae growth that is difficult to clean. Then you already realize that maintaining the optimal aquarium water temperature is vital. Here are some of the best, cheapest, and fastest methods for lowering the temperature of your tank water in the summer.

Below you’ll learn how to best use them and discover our top picks for the best aquarium Chiller.

 

A factor which helpful for Choose an Best Aquarium Chiller?

Flow rate

It is important that you get the right model with the best flow rate. The flow often determines how well the cooler can maintain the temperature of the aquarium water. You need the chiller to have the right flow, not too fast or too slow.

Energy consumption

The cooler is powered by electricity, so people sometimes worry about how much power they would use. Coolers are often designed to use less energy, so they can be useful for keeping the water temperature within the correct range. It doesn’t hurt to compare different models to find one that uses less energy.

Aquarium capacity

The current usually goes hand in hand with the capacity of the aquarium. It is always better to buy a model that has the correct flow rate for the capacity of the aquarium.

Do not use a model intended for small aquariums in large aquariums as this will not be effective. Most manufacturers include this number in the product description so that you know where to use the cooler.

The Construction

You need a model that will last for many years. This requires checking the construction material used to make the cooler. Most would be made of plastic materials with some metal parts. You have to make sure that even the plastic part lasts a long time, which will give you value for money.

Refrigerant

Today many people are concerned about the environment. That’s why you will find them by taking the time to find an environmentally friendly refrigerant.

Well, most aquarium coolers move in that direction too. First, consider the different types of refrigerants used in the chiller and see if it is good for the environment.

Noise level during operation

Nobody wants to end up with a chiller that makes a lot of noise while running. So check out what other people say about the operating sound you can expect from the model before purchasing.

Some may have tinnitus, which may not be a bad thing at first, but it can become irritating over time. Fan noise can be tolerated as it is not always easy to find a cool box without a little operating noise.

9. PETZILLA

Best Aquarium Chillers

For the budget conscious fish farmer, the Petzilla Aquarium Cooler Cooling System is the best option.

This small nano aquarium cooler is inexpensive and will keep your small aquarium cool and healthy for a long time. This little cooler works for both fresh and salt water, so whatever kind of fish you have, you’re in luck.

The Petzilla Aquarium cooling system attaches to the wall of your aquarium to lower the temperature by up to 7 degrees Fahrenheit.

The fan system has two variable speeds with a wide angle of entry and a stable and strong clamp to allow the perfect positioning to cool your tank.

  • Type: fresh or salt water
  • Tank size: 10 gallons or less per fan
  • Horsepower: unknown
  • BTU rating: unknown
  • Cooling capacity: cools up to 7 degrees

The fan is an easy-to-install option that requires no assembly. Just clip the nano aquarium cooler to the side of your tank, plug it in and watch it move.

The system uses evaporation to lower temperatures, rather than refrigerants like those used by other chillers. And if one fan is not enough, you can run up to 6 fans in one unit for cooling.

The cooling system comes with a 30-day money-back guarantee and a one-year warranty with free user support.

The only downside I found with this system is that since it uses evaporation to cool the water in your tank, you have to add more water quite often.

Also, the aquarium walls must be less than 0.5 inch thick to support the clamp size on Petzilla Chiller.

What is the Best Aquarium Chiller?

The JBJ Aquarium Arctica titanium chiller is one of the best chillers you can get on the market today. It comes with all the important features you can want in a chiller.

It is quiet in use, so you can store it in the living room without worrying about your comfort. With its highly efficient capacitor, it can consume less energy compared to other models.

 

How Does an Aquarium Chiller Work?

An aquarium Chiller works by taking the heat from the water and then transferring it to another location, such as the surrounding area. This process is often referred to as heat exchange. The cooler would have components such as the heat exchanger, expansion valve, compressor and a condenser coil.

The cooling cycle starts at the heat exchanger where the refrigerant takes the heat from the aquarium water circulating in the unit. Usually you will get a heat exchanger made of titanium, which is resistant to corrosion even when used for seawater aquariums.

The compressor then pumps the refrigerant vapor to reach the condenser when it cools down and then returns it to the heat exchanger to extract more heat from the aquarium water.

 

How to install an aquarium Chiller ?

The installation depends on the type of chiller. Basic types include a direct cooler and an inline cooler. The direct cooler has a heat exchanger that you place in the crankcase to operate. It’s that simple.

The in-line cooler has water through it to cool it down before circulating back to the aquarium. You must choose a model with the correct flow rate so that the water in the tank can be easily maintained.

Refer to the cooler’s manual for more instructions and tools you will need for the job.

 

Where do you place the aquarium Chiller?

Most aquarium Chiller are compact and take up less space. It should be easy to find multiple spaces to put them.

Make sure the Chiller is close to the aquarium water so that the water easily stays within the correct temperature range.

 

How to clean the aquarium Chiller ?

Begin by disconnecting the water line connections to the aquarium Chiller as the first step. You must do the same with the electrical connection.

For a model used for fresh water, cleaning should be easy. Simply rinse the Chiller with clean water. As for the one used with salt water, there may be some limescale build-up on the side.

Clean with vinegar to remove side deposits and finish with a clean chiller.

 

conclusion

Best Aquarium Chiller reviews will give you all the important information you need to know about the Chiller before purchasing one. This means that the next time you need to choose the right chiller, you can do it based on the right information.

By taking care of the aquarium life, you can enjoy a vibrant tank every time as the water temperature is within the correct range thanks to the Chiller. Take the time to look at the different models before deciding which one can meet your cooling needs.
