Ceramic rings are a highly porous bio-filtration media that provides an optimal habitat for beneficial bacteria to thrive. The unique ring shape allows for maximum water flow, ensuring efficient removal of ammonia, nitrite, and nitrate from your aquarium.
Directions: Use as many ceramic rings as your canister or media bag will allow. It is recommended to clean the rings every 8-12 weeks in dechlorinated water. Do not scrub the rings as this will remove beneficial bacteria.
