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 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)||4500 MAXIMUM||4500 MAXIMUM||4500 MAXIMUM|
|Free Chlorine (PPM)*||2 to 3||2 to 3||2 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 6000 ppm.
