CerMedia MarinePure 8x8x4 Inch Block

The CerMedia MarinePure Block is a ceramic bio-filter media designed for both marine and freshwater aquariums. It features a large surface area and open-flow porosity, which aids in the reduction of nitrates and the removal of ammonia and nitrates.

This bio-filter media is lighter and more efficient than traditional live rock. It is made from inert ceramic materials, ensuring it does not alter water chemistry.

Dimensions of the block are 4 inches in height, 8 inches in length, and 8 inches in width. The block weighs 3.6 pounds and comes in a color range from white to off-white.
