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.
Great for Beneficial Bacteria
Biological filtration refers to the beneficial bacteria and aquarium plants that consume toxic nitrogen chemicals generated from fish waste, thus purifying the water. Because beneficial bacteria grows on any surface area in the tank that is well-oxygenated, the filter is a primary location to boost the population. Biorings have lots of porous surfaces to serve as “housing” for the bacteria colony.
Easy to Clean
Aquarium gunk can cover these surfaces over time, so clean the bio media every 1-3 months by gently waving or rinsing it in old tank water until the debris falls off. Our bio rings come in a pre-sewn mesh bag that is easy to remove during filter maintenance.
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.
