There are a few different ways to care for the water in your hot tub or swim spa. Traditional water care includes the use of bromine and chlorine, while a more modern approach uses a mineral block with ozone, UV and chlorine. Another solution, named Free, is based on hydrogen peroxide. Additionally, many spa owners use Silk balance, an enzyme based water care method.
We have put together downloadable PDF guides for the Bromine and Chlorine method and the Ozone Mineral Block method.
