  • Promotes growth of beneficial bacteria
  • Helps reduce ammonia and 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.

Fit Perfectly

These bio rings fit perfectly in my Aqua Clear 70. I use the sponge and bio rings that came with the filter. Then the Aquarium Coop bio rings on top.
