## Description

Fluval FX4/FX5/FX6 Bio-Foam 2-pack : desertcart.ae: Pet Supplies

Review: This is another solid, name-brand Fluval product that does exactly what it’s supposed to do. I’ve used these ammonia remover pads consistently in my FX-4 filters, and they’ve been reliable every time. Easy to install, fit properly, and they help keep water quality stable, no drama, no surprises. If you’re running a Fluval FX system and want dependable ammonia control, these are a no-brainer. Steady, effective, and worth keeping in rotation. Calm water, happy fish, mission accomplished.

## 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
