How to Select the Best Axolotl Tank Filter?

There are several factors to consider when selecting the tank filter for your axolotl tank:

Type of filter and filtering layers/media

Filters are of different types: submersible, hanging, and canister.

The reason why we have selected canister filters for axolotl tanks is because only this type of filtration includes three media types for a thorough filtering action: mechanical, chemical, and biological. They are ideal for turtle and freshwater tanks since their intake is powerful and pushes the water upward from the bottom media to the top for highly accurate filtering action.

Canister filters do not work for saltwater filtering.

  • Mechanical filtering action – This removes all the waste and debris from the tank water
  • Chemical filtration – This ensures that the water’s chemical composition does not change owing to the chemical changes caused by waste generated by the axolotl.
  • Biological media – This layer adds beneficial bacteria to the water to help your pets thrive.

Size and capacity

When selecting the size of your filter a good thumb rule to follow is: select filter having a flow rate (a value in GPH or gallons per hour) that is at least 5 to 6 times the total volume of the tank.

So, if your tank size is 20 gallon, choose a filter with GPH rating of 120-150 gph.

Flexibility

Do choose a filter that lets you add your own/separately purchased media. Many brands of filters only require specific media which can be very limiting and sometimes expensive as well.

Easy to clean

You have to regularly clean your filter so please ensure that the filter you choose has an easy to remove media and also offers hassle-free cleaning.
