Made in the USA, it dissolves quickly for easy application and is trusted by thousands for maintaining crystal-clear, balanced spa water. ## Description Critical to alkalinity control, this granular formula effectively raises alkalinity levels which might otherwise cause equipment corrosion. This product is a special compound used to increase the total alkalinity in spa water. Test for total alkalinity with a reliable test kit. The desired range for total alkalinity is 80-140 ppm. This product increases the effectiveness of the disinfectant, and helps prevent scale formation. It also prevents corrosion of metals, etching of spa surfaces, eliminates “bounce”, and maintains pH at the proper level. Easy to use; dissolves quickly. 1. Add 1 oz. (2 tbsp.) to spa water. 2. Allow water to circulate for 30 minutes. 3. Retest water and repeat Steps 1 and 2 until the desired level is reached.
