Keeping your pool water balanced is an important step in getting the most out of and preserving the life of pool equipment. This product is easy to apply, just pour it directly into the pool. Alkalinity Up can be used with chlorine, bromine, ozone, salt water pools, and biguanide sanitizers.

2. If the value is below 75 ppm, add a quarter of GLB Alkalinity Up by pouring it directly into the pool to increase the total alkalinity (add more if test levels are really low)
