Salt Levels:
The system can work within a broad salinity range, from a minimum of 3000 ppm (parts
per million), up to 4000 ppm. However, the ideal level for operation is about 3400 ppm. To
achieve this level of salinity, add approximately 30 lbs of salt for every 1000 gallons of
water (or 3.4 Kilograms of salt for every 1000 Liters). If you are unsure of the number of
gallons in your pool, double-check with the following equations.
Notice: When adding large quantities of salt, start with an independent test of the existing
salinity level and add in portions, retesting at each stage.
Calculating Gallons (Measurements in Feet)
Rectangular -Length x Width x Average Depth x 7.5
Round -Diameter x Diameter x Average Depth x
5.9
Oval -Length x Width x Average Depth x 6.7
Before adding salt, check your water for any existing salt content and add according to
the chart below. If too little salt is added, the result will be reduced efficiency and a low
level of chlorine production. In addition, operation at low salt levels will reduce the
longevity of the cell. The salt in your pool is constantly recycled, and the loss of salt
throughout the swimming season should be small. This loss is due primarily to the
addition of extra water to replace water lost from splashing, backwashing, and draining.
Salt is not lost due to evaporation.
