GLB Alkalinity Up

Easy-to-use, this granular product raises total alkalinity in the pool and acts as a buffer to prevent pH bounce, staining and corrosion.

To prevent the pH from “drifting” or “bouncing” up and down, the proper amount of acid buffers, or Total Alkalinity, must be maintained in the pool. The pool should be tested weekly with a Total Alkalinity of 75-125 ppm (parts per million) maintained. Low total alkalinity can not only result in pH bounce and fluctuations, but corrosive-ness and the possibility of staining increase. High total alkalinity also can cause the pH to fluctuate as well as cause cloudy pools along with possible scaling.
