Marineland Black Diamond Activated Carbon
Improve your water's quality and clarity. 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.
