Zeolite is a volcanic lava formed a frame structure of aluminum silicate minerals. More than 50 kinds of known zeolite, natural zeolite used in a variety of aquaculture and mordenite zeolite as the main. It contains all the necessary growth and development of aquatic animals of trace elements. In addition, the zeolite also has a unique adsorption, catalysis, ion exchange, ion selectivity, acid resistance, thermal stability, multi-component nature and the high biological activity and resistance to toxicity. Zeolite pore and channel performance of a high degree of cation selective ion exchange. Will be harmful to animals, remove heavy metal ions and cyanide. In order to make useful metal ions are released. Can remove 95% of the ammonia, water purification, mitigation of water transfer phenomenon
