MARINELAND BLACK DIAMOND 1.87 L

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. 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. And now, new and improved Black Diamond works twice as fast. Black Diamond Available in 440mL, 900mL, 1.87L, 3.65L sizes.
