FAQ
Practical pool salinity questions
How much pool salt do I need to add?
The amount depends on your pool volume, current salinity, target salinity, and salt purity. This calculator estimates the salt weight in pounds and kilograms, then converts it into common bag sizes.
What salt level should a saltwater pool use?
Many saltwater chlorine generators operate near 3000 to 3400 ppm, but the correct target depends on the equipment manual. Use the brand preset as a starting point and confirm with the manufacturer.
What should I do if I added too much salt?
Salt does not evaporate out of the pool. If the salt level is too high, the common correction is to drain a calculated portion of water and refill with fresh water, then retest.
