  • 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.

You can never go wrong with buying extra bio rings. I like to keep extra on hand in aquariums to jump start new aquariums.
