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.
Biological filter media keeps aquarium clean and healthy, maintains good water quality, and keeps fish thriving
Complex pore system create optimal environment for beneficial bacteria to thrive
Use to provide biological filtration. Suitable for all external filters.
Remove protective plastic bag and rinse thoroughly with terrarium-safe, chlorine-free water. Place directly into media basket or filter chamber, depending on canister filter style. For optimal filtration, place at the end of the filtration process.
Rinse monthly using water from the terrarium. Never rinse with tap water or any water that could contain chlorine. Replace every 6 months, depending on fish load.
Do not replace all filter media simultaneously. Stagger media replacement to ensure constant bacterial populations.
Comes with a really good amount for the price. Way less expensive than other sites. Filled an entire tray in my 100 gallon canister filter with one box!
Awesome would recommend

Great product I bought these to replace the bio rings that came with my marineland filter. Chewy's price and service is the best.
Works great and at better cost too!

Anything Fluval I always love, but they're usually so expensive in pet stores. So glad I could find these at a good price. You can tell these rings are made well for beneficial bacteria to grow with their porous design. Would highly recommend as your bio media for your filter.

Needed a solution for a used canister. These worked perfectly.
Great for beneficial bacteria!

I have two huge media bags with this product, in my canister filter, and they're probably one of my favorite bio-active media. They're small, but extremely porous, and have a nice gritty surface. The hole in the middle ensures flow can get through the entire piece, and provide oxygen to the beneficial bacteria living inside it. Each piece is a tad bigger than the average marshmallow, but don't be fooled! A bag of these will act like grand hotels for the bacteria that move in!
fluval is great

I use these with the fluval sponge and it works great! My water stays very clear in all of my tanks.

Haven't used for long but it's extremely porous and seems to be helping already after only a week, can't wait to see when the bio really kicks in

Product received quickly and is exactly what I needed (replacement biomax for a Fluval 100 aquarium filter).
I will purchase this again in the future as needed from Chewy.com.
