Water Chemistry
(Corrosive water voids all warranties)

For your health and the protection of your pool equipment, it is essential that your water be chemically balanced. The following levels must be used as a guide for balanced water.

Recommended Level(s)Fiberglass PoolsFiberglass SpasOther Pool and Spa Types
Water Temp. (Deg. F)68 to 8889 to 10468 to 104
pH7.3 to 7.47.3 to 7.47.6 to 7.8
Total Alkalinity (PPM)120 to 150120 to 15080 to 120
Calcium Hardness (PPM)200 to 300150 to 200200 to 400
Salt (PPM)4500 Maximum4500 Maximum4500 Maximum
Free Chlorine (PPM)*2 to 32 to 32 to 3
Total Dissolved Solids (PPM)3000 Maximum**3000 Maximum**3000 Maximum**

*Free Chlorine MUST NOT EXCEED 5 PPM!
** In salt water chlorinated pools, the total TDS can be as high as 6000ppm.

  • Occasional chemical shock dosing of the pool or spa water should not damage the heater providing the water is balanced.
  • Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water.
    Unless controlled, they can lead to excessive chlorine level which can damage your heater.
  • Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical supplier for the correct levels for your water.
