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.
