Marineland Black Diamond Premium Activated Carbon (5 oz)
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. Product codes: PA0370 |
