Offered in a range of convenient sizes, Diamond Filtration Media works
faster, longer, better. Performance tested and certified effective by
Marineland Labs, each has been compared against the leading brands of
chemical filtration media.
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.
