Marineland Black Diamond Activated Carbon

$7.79 CAD
Size

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.
