Jungle Clear Water (Liquid) is for Established Aquariums. It quickly removes odors and cloudiness caused by decayed organics (fish waste, dead plant matter, and bacterial blooms). Converts organic matter such as microscopic plant and animal life, into relatively inert matter. Also removes iron. If using any other water conditioner or treatments, wait 48 hours before using this product. Remove activated carbon during use. Water may turn dark at first but will clear within a few hours. If cloudiness has not cleared in 48 hours, treat again.?
