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.
Love everything from Aquarium Co-oP!! Made with great care for hobbyists by hobbyists.

Great value for canister filter media
I underestimated the amount of BIO Rings I would receive per box. The value is fantastic and the prepackaged rings fit great in both my Fluval 307 and 407.

More porous
These seem to be a bit more porous than fluval biorings. They seem to work a little better too 😉

Perfect packaging for a dusty product!
I put in a big order for these. I was setting up multiple canisters, and topping of all my hang on back filter media. Typically when you order these from a company they come in a beat up plastic bag with dust everywhere. Or a box with a dust that coats everything. I like how these are boxed and bagged to keep everything clean during delivery and storage.
Product is also great. You can use it in the flow through back it comes in or cut it open and add loose to your canisters. The bag it comes in makes it easy to clean. I put water in a pitcher and violently shake and swirl it in the water until the mulm comes off.
A ton of thought went into this product and it's packaging and it is appreciated.

great filter media!!
i have a very long 33g tank (48" long to be exact) and i have one HOB on each end. i needed some stronger media to combat the mulm building up, and this did the trick! have been using it in multiple other tanks as well and it's been great!

BIO RINGS
These BIO RINGS fit perfectly in my Seachem Tidal 75. With the provided mesh bag, it makes cleaning super easy, and I can spend more time enjoying my aquarium!

Great product at a very affordable price
Great product at a very affordable price and comes with a mesh bag. I have a fairly new tank with decent number of fish with no plants. I used to clean my tank initially every 6 to 7 days as the ammonia and nitrite levels used to be above zero. Now my fish are grown, I feed a lot and still the levels are zero after 15th day, only Nitrates are at 25ppm which I know is fine. I will try to extend the tank cleaning till the 20th day and see where my levels are.

They add so much more surface area for the good bacteria.
