Directions for lowering Total Alkalinity and pH

First test the pH and Total Alkalinity of your pool water using a reliable test kit. The ideal range for Total Alkalinity is based upon the type of sanitizer used (80-100 ppm for sodium hypochlorite, calcium hypochlorite and lithium hypochlorite, and 100-120 ppm for dichlor, trichlor and bromine tablets). The ideal pH range is 7.4-7.6. Keeping the pH and Total Alkalinity in these ranges will maximize the performance of any chlorine or bromine sanitizer.

Always adjust the Total Alkalinity first.

If the Total Alkalinity of the pool water is higher than 140 ppm, it must be lowered. 2 pounds of Leslie’s Dry Acid will lower Total Alkalinity by 10 ppm in 10,000 gallons of water.

Please follow directions on the product label to properly and safely balance your pool or spa water.
