Aquascape Activated Pond Carbon successfully removes discolouration and odors in pond water. Our Activated Pond Carbon is made with bamboo carbon, a sustainable resource with an incredible ability to remove discolouration from water. The highly effective carbon also removes chlorines and chloramines, which can prove harmful to pond fish, from the water. A resealable mesh bag is included for quick and easy application. One scoop treats 25 gallons of water and the full bag will treat 800 gallons of water total.
