SpaPure(R) C002693-CS20B6 Alkalinity Increaser; 16 oz
Spa Pure Alkalinity Increaser is used to raise the alkalinity level in a spa. Total Alkalinity measures the amount of buffering capacity in the spa's water. Alkalinity acts as a shock absorber for pH. If total Alkalinity is too low, the water becomes acidic and corrodes equipment, plumbing, and more. It can also cause pH bounce.
