Fluval BioMax 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.

I try to support my LFS as much as I possibly can, but when comparing the price of this media, Amazon was an absolute steal compared to what my LFS was asking. This was a real Fluval product and I would purchase again in the future

Works great for holding filtering spung and charcoal bags in place and helps biological systems in tanks

This product is great and does exactly what it states, I would have given it 5 stars except for the fact that they are the LARGE size don't make the same mistake that I made. This is not Fluvals fault but my own, they are extremly heavy for Bio Media and only a couple of pieces can fit in most small filters. This size media is best for LARGE filters so make sure you check the SIZE of the media. I suggest the smaller size of BIOMAX.Besides the weight on the larger bio media, it does a great job. There is a lot of surface area for bacteria to grow only down side was mine came pretty smooth and the more porous the more bacteria so I had to scuff them up a bit.I do video reviews for products and will be doing some video reviews and head to head tests of BIO media by testing bacteria film on surface area and putting fluvals products against the famous K1 media and other ceramic media.I tried contacting Fluval to get some of their other smaller media to do the review on but I still have not gotten an e-mail response back so we will see.

I absolutely loved this product. It’s exactly what my fish tank needed to keep my fish healthy and happy. Since I started using it, the water looks perfectly clear and clean. You can really see the difference in the filtration, and my whole family is impressed with the results. Highly recommended for anyone who wants a cleaner, healthier aquarium.

As described.... Works well in my fluval 307.

Good media, water in tank is clear

I’m using these in a hanging container for some rooted plants. So far so good. I wanted something for the plants to attach to inside the container.Hope this is a good long term solution.
