Aquarium ozone generators are water filtration devices that use ozone to kill microscopic organisms that are free floating in the water. Using these for fish and reef aquariums will result in healthier corals, increased polyp extension, consistently clear water, proper light penetration, increased efficiency for protein skimmers, oxidation and breakdown of fish waste and uneaten food in the tank. Bulk Reef Supply carries our own line of Ozone Air Dryers as well as ozone generators from Enaly and Ozotech. We also carry a complete line of Kynar plumbing fittings which are especially designed for use with ozone and will not melt because of the contact with high concentrations of ozone.
