If you are like most Axolotl owners, you are always looking for ways to make your aquarium a better home for your pet.

One question that often comes up is whether or not an aquarium chiller is necessary for an Axolotl.

In this article, we will explore the pros and cons of using a chiller and help you decide if it’s the right decision for you. Thanks for reading!

What is an aquarium chiller, and what does it do?

It is a device that cools down the water in your tank by removing heat from it.

They are used to keep the temperature at an optimal level for Axolotls which can be hard since most rooms aren’t always cold enough, especially during summer months when temperatures rise outside.

One of my axies has a chiller, and it’s amazing how much cooler the water stays in his tank compared to my other three tanks that don’t have chillers.


There are many benefits, including:

  • The ability to keep temperatures below 65 degrees Fahrenheit, which is ideal for Axolotls
  • Helping to prevent health problems in Axolotls that can be caused by high water temperatures, such as heat stroke
  • Preventing the growth of harmful bacteria and algae in your tank

There’s really no downside when it comes to using an aquarium chiller. They help keep the water at a safe temperature for your axolotl, which is why they’re so popular.

Plus, if you have more than one Axie, having multiple chillers means that each tank can be kept cool even during the summer months or when the ambient room temperature is high.


There are a few potential drawbacks, including:

  • The cost of purchasing and running a chiller
  • The increased chance of tank crashes if the water temperature drops too quickly
  • The need to monitor and adjust the chiller settings to make sure your Axolotls are kept at a healthy temperature

Do Axolotls need a chiller?

Axolotls don’t require chillers, but they can be helpful if you have more than one Axie in your tank or live in an area that has extreme temperatures during certain times of the year.

A good rule of thumb is to keep the water temperature between 65°F and 70°F. Anything below that could cause your axolotl to get sick and die!

How cold should the water be in their tank?

You can check the water temperature with a thermometer to see if your axolotl needs an aquarium chiller.

It should be between 65-70 degrees Fahrenheit, but never below 60 degrees because that’s too cold for them!

If you’re not sure how often you’ll need one or two chillers to keep things at these temperatures, it’s best to get a couple so that they can be interchanged as needed.

How cold do aquarium chillers get?

Most aquarium chillers can have a user set range between 39°F to 90°F (3°C to 32°C).

Aquarium chillers can be set to different temperatures, but ensure that it does not go below 60 degrees Fahrenheit.

This is important because Axolotls are cold-blooded and cannot tolerate much colder water than that. More than 20 days at 39°F (4°C) is usually fatal for this amphibian.

How long do they last?

Aquarium chillers usually last for several years. The only reason why they may stop working is if there are any problems with the electrical components, but you can fix this by replacing them or getting a professional technician to do so.

Some users have reported using chillers such as JBJ Aquarium Arctica Titanium Chiller for over 15 years.

You should always check the warranty before purchasing, as some companies offer better warranties than others!

Cost of running

Aquarium chillers are not cheap to purchase or run, and they can cost anywhere from $100-400 dollars depending on the size of your tank.

You can find them online or in stores near you for around $100-$300 each, but they’re not hard to find, so don’t worry about it being an expensive purchase!

What size chiller do I need?

The size of the aquarium chiller you need depends on how big your tank is and the temperature of your room.

For example, if you are using a 55-gallon tank, then you’ll need one that’s rated for at least 20 gallons more than what’s inside your aquarium so it can cool down all those extra gallons without any problems!

Set up and maintenance

Set up of aquarium chillers is beyond the scope of this article. I will write a dedicated post about it. However, it is best to consult a professional to have it set up for you if you are facing any difficulty.

You’ll also need to perform regular maintenance tasks such as cleaning the coils or replacing the filter cartridge every few months to keep the chiller running smoothly.

If you’re not sure how to use or maintain an aquarium chiller, be sure to consult the manufacturer’s instructions before using it. There are also plenty of online resources and videos that can help walk you through the process.

What is the best type of aquarium chiller for Axolotls?

The best type of aquarium chillers for Axolotls are ones with a titanium coil. This material is corrosion-resistant and can withstand the high water temperatures common in axolotl tanks.

Final Thoughts

An aquarium chiller is a great way to keep the water at an optimal temperature for your axie.

Of course, you’ll want to make sure that you’re using it correctly and maintaining it properly to ensure longevity and keep things running smoothly over time.

Using chillers will help keep your Axolotls healthy, which means they’ll live longer, happier lives. Not to mention, they make the tank look a lot nicer with the lower water temperatures.

So if you’re thinking of getting one for your axolotl tank, don’t hesitate – it’s a fantastic decision!

That’s all for now! Thanks for reading!
