Poly/foam pads will effectively trap the largest particles in the water during mechanical filtration. First, the larger particles will be caught, while second, the finer ones will be removed.

There are three sizes of the filter: C2, C3, C4. Filtering for different sizes is provided by all of them, although the C4 is the most powerful. Installing and maintaining the filter should be pretty straightforward since it is a clip-on filter.

It does, however, take a bit to prime the button, and it might need a few presses to get started. This filter is pretty quiet and doesn’t make any noise.

What To Consider Before Buying A Filter For Axolotl

 Best Water Filters For Axolotls

To get the perfect filter for Axolotl, you must consider the following factors:

Adjustable Flow Rates

The foremost thing that you need to consider is that the filter must have an adjustable rate. Adjustable flow rate can play a significant role in choosing the right filter for Axolotl.

Axolotls can be stressed if the water flows too rapidly, and they can be sensitive to higher water flow levels. So, your filter must have an adjustable flow rate.

Ability To Process High Volumes Of Water

Another important thing is that it must have the ability to process high volumes of water. An axolotl can produce a lot of waste, and that waste can be even greater if you have other animals or plants with it. 

So, to reduce waste, your filter must have the ability to process a high volume of water.

Powerful Biological Filtration

Ammonia and nitrites, as we already discussed, can cause axolotls to develop diseases if they are too abundant in the water.

Ammonia and other harmful chemicals should be cleaned efficiently by the filter. This will only happen when your filter has powerful biological filtration.

So, to prevent diseases, your filter must have a powerful biological filtration.

A Good Sponge Filter

For blocking any larger particles from the water, a sponge filter is also essential. There’s no doubt about that, but larger particles can also increase stress levels for axolotls.

So, you must consider a good sponge filter before buying a filter for your Axolotl.

Must Be Quiet

One of the most important factors is that your axolotl filter makes no noise and must be quiet.

So make sure that the filter that you’re going to buy must operate quietly. For those who prefer low noise levels, the canister filter has a mechanism that operates very quietly.

Slow Water Flow

Fast water flow may be dangerous for Axolotl and lead to its death. The axolotl is one of the most sensitive things; even a little fast water flow can damage it. If you already have a water filter with fast water flow, you can use a spray bar that will disperse the water flow evenly.

We recommend you look for GPH (gallons per hour); this is the main indicator that helps you judge the water flow rate.


How Often to Clean Axolotl Filter?

The filter should be cleaned periodically as it can become clogged and may collect many debris, particles, and invisible materials. This can decrease the filter’s efficiency, resulting in poorer water quality.

All you need to do is clean the filter and remove any debris that has accumulated. By doing so, the filter will be able to work to its full potential.

You should also replace the filters from time to time. With some filters, you’ll be told when to do it, and with others, you’ll have to figure it out for yourself. Checks and inspections of filters are included in this process.

Do you need a water filter for Axolotls?

Filtration is not very essential for Axolotls, especially if you are regularly changing water. But most hobbyists recommend using a filter for Axolotls because water with excessive amounts of chlorine is harmful to them.

What kind of water is safe for Axolotls?

According to Ichthyologists, the best environmental temperature for Axolotls is 16-18°C. You can exceed temperature to 24°C, but a temperature above 28 is not suitable for Axolotls.  


All creatures, including axolotls, prefer to live in a clean environment. It is crucial to have a good filtration system in place. The owners of some houses prefer to clean the water themselves.

Nevertheless, if you want your axolotls to be healthy and happy, a powerful filter is essential.

So, after reviewing the above filter, you can choose the perfect one for your Axolotl. No matter, all the filters we reviewed above are best. But it is highly recommended that you consider the above factors before buying to get the perfect one.
