of bathers and will cause the sanitizer to be less effective. A low or high pH can be corrected by adding pH
increaser or decreaser.
Alkalinity:
Total alkalinity is a measure of the alkaline in the water. This acts as a pH buffer or a pH stabiliser preventing large
changes in the pH. The total alkalinity should be between 80 to 150 PPM, ideally 120ppm.
Low total alkalinity causes:
The pH to wander.
Corrosive water.
Ineffective sanitation by disinfectives.
To raise the total alkalinity add Alkalinity Increase.
