How frequent this should be changed? since its carbon impregnated.

Fluval says once a month... To me It all really depends on water change regime.

Do these also fit the fluval fx4?

Every single part/pad etc made for FX4/5/6 are interchangeable with the exception of the pump motor for FX4. Everything else and I mean everything else fits all FX series.

Can this be used for preparation for an Axolotl? And if so, is it recommended?

I am not sure. Using it helps in toxic ammonia. Your critter lives in murky, muddy water I believe. Ammonia can build up anywhere. You might get contact your pet store. Sorry
