Use Pool Acids to Restore Proper pH Range

Written by Samanatha Grieg | November 26, 2024

Water balance is a crucial part of pool maintenance. Without it, your pool water could corrode metal, be so cloudy you can’t see through it, or, most importantly, be a breeding ground for bacteria.

You may be familiar with the Langelier Saturation Index (LSI). This index is a “go-to” calculation for pool managers to determine if their water is balanced, safe and healthy. The LSI of water is determined by the water’s temperature, calcium hardness, total alkalinity (TA), total dissolved solids and most importantly, the pH. A pH range between 7.2 and 7.6, and a free chlorine between 1 to 4 ppm will help ensure the healthiest, safest water. 

How does pH affect safety? First, having high pH pool water, around pH 8 or higher, can increase the chance that the water may become cloudy. While the water still may be somewhat chemically safe, it now presents a bigger risk for drownings…
