SpaPure's Alkalinity Increaser is a smart formula to combat low levels of alkalinity, which if left untreated can cause corrosion damage, weaken your sanitizers ability to keep your spa clean, and cause skin and eye irritation. When alkalinity is balanced correctly, the water will be less likely to cause damage from corrosion or scale.
