Water Balance

pH is the most important element in swimming pool water chemistry - it affects every other chemical balance in the pool water.  pH is a scale for measuring the pools acidity or alkalinity level.  The pH level indicates the relative acidity or alkalinity of your pool water.  pH is measured on a scale from 0 (strong acid) to 14 (strong alkaline) and pH neutral is 7.  In pools a slightly alkaline level between 7.2 & 7.6 is ideal because this range is the most comfortable to the human eye, provides optimum use of free chlorine and provides water that is not corrosive or scale forming.

If pH falls too low (below 7)
  • Water becomes acidic, eye & skin irritation occurs.
  • Corrosion - Heater element may corrode (unless you have Titanium heating elements) the pump impellor & other metal fittings on the pool will corrode.
  • Dissolved metals may leave stains on the walls.  Rapid loss of alkalinity and wrinkling of Liner.
If pH is too high (above 8)
  • Chlorine activity is slowed and inefficient.  Scale formation and discolouration of pool walls.
  • Water becomes cloudy and the filter is overworked & may become clocked.
  • Eye & skin irritation may occur.
  • pH Minus Granules
