Fluval Biomax Bio Rings Filter Media, 17.6-oz
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.
Key Benefits- 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
- More capacity than most biological filter media
- Allow ideal water movement throughout the media

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!

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!
By Ellie on Mar 4, 2018
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.

Great for beneficial bacteria!
By CatCatCatfish on Jun 4, 2017 Top 250 Contributor
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!

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.
