Containing a superior blend of resins and activated carbon that removes aquarium pollutants – including colors, odors, heavy metals, and toxic gases – API Bio-Chem Zorb filtration media makes aquarium water crystal clear. The product also removes light blocking impurities for improved growth of corals in saltwater, and for plants in freshwater aquariums.
Rinse the pouch under tap water to remove the loose dust. The pouch does not need to rinse clear. Place pouch in the path of water flow in the aquarium filter. Replace every 2 months, or sooner if the aquarium is heavily stocked and/or colors or odors are detected.
