Mineral Harmony Guard (Stain & Scale) 16oz.
Mineral treated spas require the regular testing and balancing of the water for the minerals to perform properly. Mineral Harmony was developed exclusively for use with mineral treated spa water.
Mineral Harmony GUARD is a concentrated product that suspends and neutralizes mineral elements that can stain and corrode your spa. Mineral Harmony GUARD also acts as a clarifier to cluster unfilterable microscopic minerals together so that they can be removed in the filtration process.(16oz)
