Super Porous Ceramic Rings

Clog-free ceramic cylinders creates a faster bacteria colonization for biological filtration. Incorporates the latest technologies in molding and baking processes. Super porous structure provides a vast surface for bacteria to grow and colonize, greatly improving the biological filtration capacity of your aquarium filter.

While a cluster of Super Porous Ceramic cylinders provides mechanical filtration, the conduit of each cylinder lets water flow freely, exposing it to a greater area of the bacteria-colonized surface. For marine and freshwater use. Mesh bag of cylinders contains 3.5 cup volume, 24 ounce weight. Each cylinder measures approximately 3/8" long x 3/8" diameter.
