The Filstar Nitra Zorb is a water filtration media that removes ammonia, nitrite, and nitrate. It offers a blend of natural and synthetic ion-exchange resins that selectively remove ammonia, nitrites, and nitrates. These chemicals are harmful to fish health. It is design for use when setting up a new aquarium. To use, remove filter pouch from plastic bag, leaving the pouch unopened. Rinse the pouch in tap water to remove any dust and then place it directly into the filtration basket. Be sure to change the filter every one to three months depending on stocking density and water quality. For freshwater aquariums only.
