  • 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.

Review of Bio Rings

Great help and simple to store! If you don't have a big filter like me and just have a nano pump you can put them in the filter loose. It's so simple!

Bio Rings

Bio rings added enough surface area to help clear my dirtied aquarium. Will be used on next tank as well.

Great quality

Great product! You can't beat the price for the amount you get; they come in a media bag which is nice and I liked that it had some texture and roughness outside compared to some of the similar design but very smooth. Will buy again when I need more media forsure!
