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 eciency 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.
