Fluval BioMax Biological Material Remover, 500 g - Biological Filter Media for Aquariums

This BioMax biological material remover is a perfect component to include with a Fluval canister filter, we have the Fluval FX4 for our red eared slider in a 55 gallon tank and this helps keep the water crystal clear for extended periods of time. If you've always struggled keeping a turtle tank clean, a canister filter with this biological material is definitely going to save you a lot of time and headache.

Muy bueno lo recomiendo

Unlike polished alternatives, the Biomax’s rough texture and maze of tiny crevices offer an ideal haven for nitrifying bacteria, creating a thriving mini-ecosystem inside each piece. This translates to faster bacteria colonization, meaning fewer ammonia spikes and beautifully balanced water parameters—a win for the fish and for any dedicated aquarist.And it’s not just the quality; at this price point, it's a serious deal, especially with Prime shipping adding convenience. Pro tip: grab more than expected! Remember to rinse them in aquarium water (not tap water!) to preserve all the beneficial bacteria hard at work. This simple step is key during filter maintenance to keep that beneficial colony going strong without wiping it out.While Fluval recommends replacing these every six months, any seasoned aquarist knows ceramic media is practically immortal. It’s fantastic for seeding a new tank filter, making the cycle period shorter and saving valuable time. The only tiny drawback? They’re a bit bulky, so they might not fit snugly into smaller tanks with compact filters.

Seems to keep the tank clean and the water clear.

Good stuff

I have always used this bio-media in all of my tanks. It always does what it is ment to do, and that is hold good bacteria in the tanks. I will continue to use this media in all future aquariums. Comes with plenty of media for most medium sized tanks also.

I love fluval products. These were exactly as expected.
