  • 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.

Bang for your buck

If your shopping for bio media, look no further. This stuff is great and you get way more than you are paying for. It fits perfectly on one side of an Emperor 400 filter and leaves room on top of it for chemical media. The small media bags they sell work really well. Thanks Cory.

Bio rings

I got these to use instead of the biomax for my aquaclear hob filters. The bags are much bigger than I expected and so are the bio rings. I was easily able to take them out of the bag they come in and put them into the ACO filter media bag to fit it into my filters. Great price for the amount you get.

Great product from an even better company

As always a quality product delivered faster than I expected. Aquarium co-op never disappoints.

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
