The combination of Ozone and UVC water treatment is a killer combination, literally if you’re bacteria and viruses. Acting as an an industry leading active water treatment system, water is treated by this combination of technologies as it’s being circulated by the pumps. Ozone is injected, while water is passed by the killer rays of UVC. This technology will make your hot tub easier to maintain, while reducing the amount of chemicals needed to keep your hot tub water clean. We highly recommend this upgrade.
