Balanced Water

Balanced Water Calculation / Langelier Index is used to determine the corrosive or scale forming nature of pool water.
Parameters used to determine the Langelier Index are:

  • pH
  • Temperature
  • Alkalinity
  • Calcium Hardness
  • TDS

Some modern pool photometers such as the PM 600, PM 620 and PM 630 will automatically calculate the Langelier Index. When using Comparator Systems or other visual Balanced Water Kits, a table is provided to enable Balanced Water calulations to be performed.

There is also a Free Balanced Water App now available for download for iOS and Android.
