  • 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.

Boosts bio filter

These rings came in a nice free flowing bag to place wherever you need them or you can cut the bag open and distribute them where you need them. There were more than I expected, it is a great value.

Good surface are for bacteria to grow on!

Plenty of bio rings, good quality, just make sure to handle them in an area where you don’t mind dust to fall on. Highly recommend them

Nice and Chunky

This is the first time I have used bio media other than AquaClear, and I gotta say I like Aquarium Co-Op Bio Rings more. I like that they’re nice and big and chunky. Using with small media bags in my hang-on-back filters.
