Adding Salt to the Pool

6

5. ADDING THE SALT

A. Distribute the determined amount of salt evenly around the
pool. To avoid clogging the filter or damaging the control panel
and pump, 

do not add salt through the skimmer or surge

tank

. Brushing the bottom helps dissolve the salt.

B. Keep the pump on to circulate the water.

C. The readout on the chlorine generator may fluctuate until
the salt is fully dissolved.

6.

  Maintain salt level of 3000 - 4500 ppm at all times. Check

salt level regularly by turning the control knob all the way to
HIGH. If all lights up to #7 are lit, salt level is in the right range.
It is also recommended to periodically test the salt level by a
professional.

Gallons

Length x Width x Average Depth x 1000

Diameter x Diameter x Average Depth x 785

  Oval

Length x Width x Average Depth x 893

3. ACCEPTABLE SALTS

GOOD 

BAD – do NOT use:

  The best salt is an evaporated, granulated, food quality salt. 

Iodized salt.

  Water softener salt pellets may be used but will take longer

Salts with anti-caking agents of more than .1% (i.e. yellow 

  to dissolve.

prussiate of soda or sodium ferrocyanide) because they 
contain iron and will yellow the fittings.

  “99.9%” pure salt. 

Rock salt because of the dirt mixed with the rock salt.

  “Solar” salt. 

Calcium chloride; it is not a salt.  Use only sodium chloride.

4. DETERMINE SALT AMOUNT

The table below is based on a salt concentration of 3500 ppm (approximately 1/3 of 1%). More may be added for larger 
pools (e.g. 4000 ppm) and less for very small bodies of water. Locate the pool’s current salt concentration at the top of the chart
(e.g. 1000 ppm). Then locate the size of your pool on the left (e.g. 12,000 gallons). Run these figures down and across until they
meet. That number is the number of pounds of salt required for your pool.
