  • 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.

Eva Filtration Bio Rings
1

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.

2

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.

One of the best one-time purchases

I've used similar materials in the past. I bought these to set up a new nano tank for my office.The beauty of these is that there is almost no need to ever replace them!

I forget they are there, so that’s a good thing!

Until I go to rinse out my filter I forget these are even there, but have had much more tank stability since adding

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 😉
