## Questions & Answers

**Q: How frequent this should be changed? since its carbon impregnated.**
A: Fluval says once a month... To me It all really depends on water change regime.

**Q: Will these work in the FX4 or are they a different size?**
A: Yes. It will fit your FX4.

**Q: Do these also fit the fluval fx4?**
A: 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.

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