Spectrum Marineland Black Diamond Activated Carbon 40oz 1134g

Product Information:

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.
