Reefing Art's ceramic bio filter media is a box of 24 porous ceramic pieces meant to sit in a sump, canister filter or pond filter as biological filtration. The porous internal structure gives bacteria a large surface to colonize, which is what converts ammonia and nitrite into nitrate. It is non-metallic ceramic, so it will not leach aluminum or heavy metals, and it works in freshwater, saltwater and ponds. Against sintered glass and plastic bio-balls, ceramic rings like these hold more usable surface per volume but are heavier and can trap debris if not rinsed.
