Salt Level
Use the chart on page 10 to determine how much salt in pounds or (Kgs) need to 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 recommended salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being
ideal. If the level is low, determine the number of gallons in the pool and add salt according to the
chart on page 10. A low salt level will reduce 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 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) salt that is greater than 99% pure. This is common
food quality or water softener salt and is usually available in 40-80 lb. bags labeled "Coarse Solar
Salt" or "Pool Salt". 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 11 to determine how much stabilizer must be added to raise the
level to 50 ppm.
