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 bal- anced water.

Recommended Level(s)

Fiberglass Pools

Fiberglass Spas

Other Pool & Spa

Types

 

 

 

 

 

 

 

Water Temp. (Deg. F)

68 to 88

89 to 104

68 to 104

 

 

 

 

pH

7.3 to 7.4

7.3 to 7.4

7.6 to 7.8

 

 

 

 

Total Alkalinity (PPM)

120 to 150

120 to 150

80 to 120

 

 

 

 

Calcium Hardness (PPM)

200 to 300

150 to 200

200 to 400

 

 

 

 

Salt (PPM)

6000 MAXIMUM

6000 MAXIMUM

*Free Chlorine MUST NOT EXCEED 5 PPM!

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.
