Pool Basics Alkalinity 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.

• Maintaining a desirable total alkalinity reading is critical to holding chlorine residuals
• PH levels are easier to control with a corrected total alkalinity
• Alkalinity acts as a buffer, improving the ability of your pool water to resist pH fluctuations
