The Balboa Ultrazone Ozone Generator is a power ozone generator with its small compact design that uses dual voltage and produces a powerful ozone oxidant which can reduce the amount of chemicals needed to maintain hot tub water quality. Compatible with chlorine or bromine systems that are ozone ready. This component is basically brand new as it was purchased new recently for a hot tub that had a leak, however it was only installed for a few hours before the hot tub was deemed un-repairable.
