RAISES ALKALINITY TO IDEAL LEVELS!
Balanced water chemistry is the first, most important step to clean, sparkling water. Raising alkalinity to the "safe zone" of 80 to 150 ppm makes your pH easier to keep in line and makes your sanitizer work more effectively. Use Spa Alkalinity Up to stop the eye irritation and corrosion that can result when your alkalinity drops below 80 ppm.
