New unused, in original box Red Sea Aquazone 50 mg/hr Ozonizer for Aquarium Filtration, Unit Includes 250 gram reusable air dryer.
Applying ozone to your tank raises
the ORP, increasing oxygen levels and decreasing dissolved wastes; ozone also effectively kills bacteria and other harmful
pathogens and breaks down ammonia and organic waste materials, AquaZone ozonizer`s corona
discharge technology provides higher ozone concentration than UV bulb style
ozonizers and allows variable ozone output.
One of the most visible results of ozone as part of aquarium filtration is the
change in the water's color from an unappealing yellow cast to a healthy
looking natural clear color.
