Water Balance
Water Balance is as important for water in a spa or hot tub as
it is for swimming pool water.
What is water balance?
It is a combination of pH, Total Alkalinity and Water
Hardness.
pH is measured on a scale of 1 to 14. Seven is neutral. Below
7 is acidic or corrosive and above 7 is alkaline. The pH also
effects the killing power of the sanitiser.
Incorrect
pH levels can cause skin and eye irritations, poor
sanitiser efficiency, cloudy water, scale formation on walls
and fittings and corrosion of equipment.
The recommended level for pH in a spa or hot tub is
7.4 – 7.6ppm (parts per million).
