Originally conceived and formulated for the marine aquarium, CHEMI-PURE has also proven invaluable to the more serious fresh water aquarist who desired the finest and purest water available for fish, such as Discus and African Cichlids, etc., as CHEMI-PURE removes the ammonia and other nitrogenous waste products so harmful to these and other fish.

CHEMI-PURE does not remove trace elements and is the only filter medium which aids in the natural balance of positive and negative charges, with an emphasis on the beneficial negative ion. CHEMI-PURE comes packed in pure polyester filter bags in sealed plastic bottles, called 1 unit, one of which is recommended for up to 40 gallons of water, and which is completely active for 4-6 months with no 'regeneration' or cleaning required and is cheaper than carbon or pads.
