Questions people ask
What is the ideal salt level for a pool?
About 3,200 ppm suits most salt chlorine generators, inside a working range of 2,700 to 3,400 ppm. Your own unit's manual is the final word.
What happens if pool salt is too low?
The chlorine generator makes less chlorine and most units show a low-salt warning or shut the cell off to protect it. The Pentair IntelliChlor manual, for example, says the unit turns off below 2,600 ppm.
What happens if pool salt is too high?
The water can taste salty and very high levels raise the risk of corrosion on metal fittings. Pentair flags levels above 4,500 ppm and Jandy warns above 4,000 ppm. The only fix is to dilute with fresh water.
