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

Pricey but do a good job

I think to be honest that too expensive for what they are however obviously we pay for the brand. They're good enough and work perfectly fine as expected. With regular maintenance they just clean out quite thoroughly with a simple rinse in some aquarium water.
