Water Chemistry Salt Level; Type Of Salt; How To Add Or Remove Salt - Hayward Goldline Controls Aqua Logic AQL-P-4 Operation Manual

The pool's chemistry must be balanced BEFORE activating the Aqua Logic's optional chlorinator func-
tion. NOTE: If the pool does not have new water, add metal remover and non-copper based algaecide
to the pool, per manufacturer's instructions. This ensures a quick, troublefree transfer to the Aqua Logic
system.

Salt Level
Use the chart on the following page to determine how much salt in pounds or (Kgs) should be added to
reach the recommended levels. Use the equations below (measurements are in feet/gallons and meters/
liters) if pool size is unknown.

The operating salt level is between 2700-3400 PPM (parts per million) with 3200 PPM being optimal.
Before adding any salt, test the salt level. This is especially important for retrofit installation to older pools
where chlorine added to the pool over time has ended up as salt. If the level is low, determine the number
of gallons in the pool and add salt according to the chart below. A low salt level will reduce the efficiency
of the sanitization and result in low chlorine production. A high salt level can cause the Aqua Logic to stop
chlorinating. The salt in your pool/spa is constantly recycled and the loss of salt throughout the swimming
season should be minimal. 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) salt that is greater than 99.0% pure. This can be found
at most pool stores in 40-80 lb. bags labeled "for use in swimming pools". Alternatively, use common food
quality or water softener salt that is at least 99.0% pure. It is also acceptable to use water conditioning salt
pellets, however, it will take longer for them to dissolve. Do not use rock salt, or salt with more than 1%
of yellow prussiate of soda, salt with anti-caking additives, or iodized salt.
How to Add Salt
For new plaster pools, wait 10-14 days before adding salt to allow the plaster to cure. Turn the circulating
pump on and add salt directly into the pool. Brush the salt around to speed up the dissolving process—do
not allow salt to pile up on the bottom of the pool. Run the filter pump for 24 hours with the suction coming
from the main drain (use pool vacuum if there is no main drain) to allow the salt to evenly disperse through-
out the pool. The salt display may take 24 hours to respond to the change in salt concentration.
Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together.
Use the chart on page 28 to determine how much stabilizer must be added to raise the level to 80 ppm.
