Adding Salt to the Pool
1. BEFORE ADDING THE SALT
• Measure existing salt in your pool: Previous use of
liquid chlorine may cause the salt reading to be higher
due to residual salt.
• New cement or gunite pools: Wait at least 10-14 days
or follow your builder’s instructions for plaster to cure
before adding salt or operating the POOL FROG® Mineral
Hybrid Generator.
• Biguanide Pools: Before installing POOL FROG®
Mineral Hybrid on a pool using Biguanide sanitizers, all
Biguanides must be removed (see dealer for details).
2. 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
to dissolve. Salts with anti-caking agents of more than .1% (i.e. yellow
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.
3. CALCULATE THE SIZE OF THE POOL
Gallons (dimensions are in feet) Liters (dimensions are in meters)
Rectangular Length x Width x Average Depth x 7.5 Length x Width x Average Depth x 1000
Round Diameter x Diameter x Average Depth x 5.9 Diameter x Diameter x Average Depth x 785
Oval Length x Width x Average Depth x 6.7 Length x Width x Average Depth x 893
The table below is based on a salt concentration of 3500 ppm (approximately 1/3 of 1%). Locate the pool’s current salt
concentration at the top of the chart. Then locate the size of your pool on the left. Run these figures down and across
until they meet. That number is the pounds of salt required for your pool.
4. DETERMINE SALT AMOUNT
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 dis-
solve 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. It is also recommended to peri-
odically test the salt level by a professional.
Example: 15’ X 30’ Rectangle Pool 3’ shallow end, 6’ deep end.
15 wide x 30 long = 450 sq ft x 4.5 avg depth x 7.5 gal per cubic ft = 15,147
