EcoBio-Pebbles are made of porous volcanic rock and cement containing beneficial bacteria and nutrients that regularly multiply to create a healthy ecosystem. EcoBio-Pebbles can be put in a mesh bag or in an old, clean nylon and placed in a filter or in the tank or simply sprinkled on the bottom of the tank (some of them may float for awhile though).
