Protect Plus


Metal Free is a powerfully effective hot tub metal, stain, and scale preventer which clears up and inhibits formation of rusty (iron), green (copper), brown or black (other minerals), or cloudy precipitates in spa water. Helps prevent scale, corrosion, and metallic odor. Most discoloration is from metallic source water impurities or a result of low pH on metal heater parts and equipment. Use Metal Free periodically, and these problems are gone. Essential for well water.
