Saltwater & Salt
Salt and saltwater tools: how much salt to add to reach a target ppm, raising or lowering salinity, and converting a fresh pool to salt. Dosing is an estimate — follow the product label and re-test.
Safety: Dosing results are estimates. Always follow the product label, add one chemical at a time, never mix pool chemicals, add chemical to water (never water to chemical), store safely out of reach of children, and re-test the water before swimming. Add about ¾ of the dose, re-test, then adjust. Not a substitute for professional pool service.
