ABSTRACT:
A composition for enhancing the clarity of liquid media, for example, in aquariums comprises a major amount by volume of vermiculite particles and a minor amount of filter medium particles. The vermiculite acts to improve the propagation of aerobic bacteria which, in turn, help to remove toxic waste products from the tank. A particularly preferred filter medium involves particles of molecular sieves. In addition, the composition preferably includes a minor amount of sodium chloride. The composition is used by combining it with conventional aquarium gravel.
