  • Promotes Growth of Beneficial Bacteria
  • Helps Reduce Ammonia & Nitrite Over Time
  • Easy to Clean and Long-Lasting

Beneficial bacteria are the key to a healthy aquarium system as they effectively remove toxic ammonia and nitrite from the water column. Improve the good bacteria count in your aquarium by adding bio rings to your filter. They are great for use in canister filters, hang on back filters, sumps and more. The shape and porous design of these rings is intended to maximize the amount of surface area for beneficial bacteria to live and for water to flow freely through the rings.

too new

They are certainly as advertised, and there are a lot of them. As to whether or not they are of any value, it's too early to tell (and I'm not sure how to tell if they do anything or not...but they won't hurt and it's always fun to try new stuff).

Great bio material!

Works great!
Comes in a pretty big bag so did have to separate for my HOB filters but it’s great stuff!

If Cory sells it I know it's good!

Very impressed with how Cory from Aquarium Co-op does business. If he doesn't believe in a product, it is not in his store. I trust him. If he says it's good I buy it and I have not been disappointed yet. Love watching his videos!

Denitrifying bacteria

Bio rings are a great addition to mechanical filtration. It grows denitrifying bacteria, deep within its pores away from oxygen which aids in keeping your nitrates low by feeding on them.
