Marineland Black Diamond Activated Carbon
$17.99 – $28.99
Black Diamond® Media 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 Media granules are specially sized and far more efficient than inferior coconut, wood or peat-based carbons. Black Diamond Media works as much as twice as fast as the competition.
