The perfect biological filter substrate made from 100% Zeolite. Natural ion-exchange resins trap the toxic ammonia on the surface of the Ammo-Rocks. The growth of nitrifying bacteria is stimulated by the high surface area concentration of ammonia. The nitrifying bacteria grow faster and produce larger and more active colonies in the filter.
