Pounds and 40 lb bags of salt to bring a salt-water pool to 3200 ppm (or your generator’s level).
How it works
Test the salt (strips or the generator’s reading), enter your pool volume and the level your generator wants.
Pounds of salt = ppm to add × gallons ÷ 120,000. Too much can only be fixed by draining, so add in steps and retest after a day of circulation.
Example: 10,000 gallons of fresh water to 3200 ppm: 267 lb, about 6.7 bags of 40 lb. 15,000 gallons from 2800 to 3200 ppm: 50 lb.
Frequently asked questions
How much salt does a pool need?
From fresh water to 3200 ppm: about 267 lb per 10,000 gallons. Then only small top-ups after splash-out, backwash or rain.
What if I added too much salt?
Only fresh water brings it down: replacing 10 % of the water lowers it 10 %.
What salt do I use?
Pool salt: 99 % pure sodium chloride with no iodine or anti-caking additives.
