API Super Activated Carbon makes your aquarium crystal clear with its premium-grade, high porosity carbon for maximum absorption and minimal aquarium maintenance, removing dissolved organics, colors, toxins, and fish remedies. This product will not raise phosphate levels in your tank, and will not affect pH. It comes in a convenient, easy-to-use pouch and is compatible with freshwater and saltwater aquariums.
Rinse the pouch under tap water to remove any dust. The pouch does not need to rinse clear. Place pouch in the path of water flow in the aquarium filter. Replace every month or sooner if the aquarium is heavily stocked and/or colors and odors are detected.
