Salt Level
Use the chart on page 10 to determine how much salt in Kgs need to be added to reach the recommended levels. Use
the equations below if pool size is unknown.
The ideal salt level is between 2.7 g/l (2700 ppm) - 3.4 g/l (3400 ppm) with 3.2 g/l (3200 ppm) being ideal. If the level is
low, determine the number of M
the efficiency of the Salt & Swim 3C and result in low chlorine production. A high salt level can cause the Salt & Swim 3C
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
3.5g/l [3500 ppm] - 4.0 g/l [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) salt that is greater than 99% pure. This is common food quality or water
softener salt and is usually available in 25 kg (55 lbs) bags. It is also acceptable to use water conditioning salt pellets,
however, it will take longer for them to dissolve. Do not use rock salt, salt with yellow prussiate of soda, salt with anti-
caking additives, or iodized salt.
How to Add or Remove Salt
For new plaster pools, wait 10-30 days (check with you local pool professional) 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 vac if there is no main drain) to allow the salt to evenly disperse throughout the pool.
The only way to lower the salt concentration is to partially drain the pool and refill with fresh water.
Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together. Use the chart
on page 10 to determine how much stabilizer must be added to raise the level to 25 ppm maximum (Use stabilizer only if
necessary).
