Scaling is most often an indication of high calcium hardness or high pH/alkalinity.

  • If alkalinity is too high, the pH will tend to increase, causing chlorine to lose efficiency, water to turn cloudy, and deposits to form (scaling).
  • If hardness is high, water is hard, which means increased scaling, scale build-up and precipitation.


  •  Balance pH and alkalinity and use 3-Met-O.
