Keep your aquarium clean and healthy by growing beneficial bacteria with Fluval Biomax Bio Rings Filter Media. One of the most important ways to maintain good water quality and keep your fish thriving is seeding your aquarium with good bacteria. This bacteria breaks down harmful ammonia from fish waste and other organic matter and starts the aquarium nitrogen cycle. Fluval Biomax Bio Rings Filter Media have a complex pore system creating an optimal environment where this beneficial bacteria can thrive. These small, cylindrical filter media have more capacity than most biological filter media, allowing aquarium water to have optimal contact time for efficient biological filtration that reduces and controls ammonia.

- Complex pore system create optimal environment for beneficial bacteria to thrive

Great for canister tanks
By Kadotah on Jun 12, 2020
These are a great deal for the price and are a one time purchase so you can’t go wrong. I rinse them in a bucket with aquarium water after each water change and have never had any problems.

great bio filter media
By Keeper on Jan 15, 2020 Top 250 Contributor
I usually use this product for my aquarium, but I had decided to change to a different bio media when I couldn't find it at the store. After 2 months, I noticed my fish weren't doing so well. So I changed back and they are healthy again.

I love these things. They are bigger than I had expected, but I have them placed in my HOB filter and it's doing wonders for my tank. Glad I got these. Very satisfied with my purchase.

Fluval Biomax Bio Rings
By AmyLuthien on Jul 2, 2019
I purchased these to replace some plastic bioballs that came with a canister filter I had. The porous nature of these rings will support a much larger colony of beneficial bacteria than any of the plastic balls available on the market.
