Red Sea Deluxe Aquazone 200 Ozonizer Apply the AquaZone correctly to aquarium water and the ozonizer kills bacteria and other harmful pathogens and breaks down ammonia and organic waste materials, raising the ORP to desirable levels. The change of the water's color, from an unappealing yellow cast to a healthy looking natural color, is one of the most visible results of ozone as a part of aquarium filtration. There is an easy to read backlit digital display. It is very simple to adjust the ozone output and desired ORP as you only need to dial in the amount of ozone that your tank needs. There is no regular maintenance required, even though there is a continuous display of current OPR. Features: · Decreases dissolved wastes · Increases oxygen levels
