In areas of soft water or if stabilised chlorine tablets are used as a sanitiser in the pool or spa water it will be necessary to add alkalinity to the water.
Water that is low in alkalinity is corrosive to pool pumps, pool heaters and tile grout, alkalinity plus (builder) should be used to prevent this. Alkalinity Plus (builder) will also slowly increase the pH of the pool or spa water. In hard water areas the alkalinity level will already be sufficient.
Alkalinity Plus (builder) can be used to increases the alkalinity level in swimming pools, spas or hot tubs.
