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.

Hydor Bio-Rings for freshwater and saltwater aquariums are created through the high-temperature sintering of inert quartz. Thanks to the macroporous structure, Hydor Bio-Rings is the perfect substrate for biological filters where the main goal of the hobbyist is the development and growth of bacteria colonies (aerobic and anaerobic) on the large surface area available (8.25 m2 per litre of Bio-Rings). Bio-Rings do not release phosphates, heavy metals, and does not change the pH of the aquarium.
