Question: Biological filtration without a sponge filter on?

[Beth]

Hi everyone,

I have only had experience of keeping an adult axolotl so far, but today became the proud owner of an, as yet unnamed, two month old wild type (thank you, Sue Baker!). It is only 5cm long and struggles to move around the tank with my Fluval One Plus filter on, so I've switched it off and it's having a much happier time swimming about now.

Does anyone have any advice on the best way to maintain my biological filter and keep the tank oxygenated without the filter switched on, please? Should I perhaps get an air-stone and lots of porous things until it has grown more?

Thanks,

Beth

Yes, I would recommend an airstone. Any tank decor with a rough surface, such as rocks, will provide a good surface for biofiltration.

Thanks!

I assume as it's so small, it won't be creating a huge amount of waste anyway, I clear up leftover food and poo, and don't have any real plants in the tank, but I'll be prepared for frequent water testing and changes just in case.

I saw it get more and more confident about swimming around the tank as the evening went on, so am really glad I switched it off!
