FluvalBioMax Biological Material Remover, 500 g - Biological Filter Media for Aquariums

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.

These filters make a great difference in the cleanness of the water.

Works perfectly with my fluval

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.
