Pool Mate Total Alkalinity Control is used when pH levels fluctuate widely over a short period of time
A low total alkaline reading is also indicative of corrosive pool water, a blue or green cast to the water, and difficulty in holding chlorine residuals
Low alkalinity can cause equipment and plaster damage
If the alkalinity is too low or too high, the pH of the pool water will be difficult to maintain in the proper range
To keep pH level stable and chlorine working effectively, total alkalinity readings should measure 100-120ppm
To increase the total alkalinity level by 8ppm, add 1 pound per 7500 gallons of pool water.
