  • 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.

Bio rings

Straight forward and do the job. Pro tip: ask for them to be wrapped in paper for shipping otherwise you’ll have ceramic dust on everything

I have a 20 Gallon tank and I put a few in my filter. They were a little dusty so I got a bowl of aquarium water and cleaned them.

Really great place

I stumbled upon this site while looking for live plants for my betta. I will purchase more from this site. Shipping was super fast even with the holiday and the plants came quickly in great condition in a neat packing bag.
