Emperor Aquatics (Pottstown, PA) offers Filter Clay, a multi-function filtration medium made from clay finely ground and baked at a consistent particle size. Intended for use in both mechanical and biological filter applications, the material works as a substitute for fine sand and has a highly porous surface that makes it ideal for bacterial colonization.
