Salt Level
Use the chart on page 4 to determine how much salt in Kgs (or lbs) needs to be
added to reach the recommended levels. Use the equations below (measurements
are in meters/liters and feet/gallons) if pool size is unknown.
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. If
the level is low, determine the number of gallons in the pool and add salt according to the chart
on page 4. A low salt level will reduce the efficiency of the Aqua Trol Above-Ground Pool
Automation and result in low chlorine production. A high salt level can cause the Aqua Trol
Above-Ground Pool Automation to shutdown and may begin to give a salty taste to your pool
(generally, the salt will begin to be tasted at a level of about 3500-4000 ppm). 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 water because of splashing, backwashing or draining
(because of rain). Salt is not lost due to evaporation.
Type of Salt to Use
It is important to use only sodium chloride (NaCl) that is 99% pure. This is common food quality or
water softener salt. It is usually available at building supply stores in 20kg - 40kg (44-88 lbs).
bags labeled "Coarse Solar salt". Do not use rock salt, salt with more than 1% yellow prussiate of
soda, salt with more than 1% of anti-caking additives, or iodized salt.
How to Add or Remove Salt
Turn the filter pump on and add the salt directly into the pool. Brush the salt to speed up the
dissolving process--to not allow the salt to sit in a pile on the bottom of the pool. Run the filter
pump for 24 hours with the suction coming from the main drain (use the pool vacuum if there is
no main drain) to allow the salt to evenly disperse throughout the pool. The salt display may take
24 hours to respond to the change in salt concentration.
The only way to lower the salt concentration is to partially drain the pool and refill with fresh
water.
