    Black diamond premium activated carbon eliminates discoloration, odors, and impurities and keeps on doing it long after other carbons quit. Heat-activated bituminous coal-based black diamond granules are specially sized and far more efficient than inferior coconut, wood or peat-based carbons. Premium black diamond works as much as twice as fast as the competition.
