Pool Salt PPM Calculator
Dial In Exact Parts Per Million (PPM) Salinity
Need to increase your salinity by 500 PPM or 1,200 PPM? Our PPM engine calculates the precise weight of salt needed for any volume and converts parts per million into actionable pounds and kilograms.

Salt Required
Required salt to reach target salinity.
Common sizing for most stores in the United States.
Standard package size in Canada, UK, and Australia.
Safe Dissolving Advisory: Pour the salt bags directly along the deep end perimeter of your pool. Turn on your primary filter pump and brush the salt heaps until they are completely dissolved. Maintain circulating currents and keep your salt cell chlorinator turned off for 24 hours while the salt disperses to avoid low/high voltage spikes.
Prevent liner staining and cell scale by using fast-dissolving, high-purity pool-grade evaporated salt.
The Golden Chemical PPM Formula
To raise salinity by 1 PPM requires exactly 8.34 lbs of pure salt per 1,000,000 gallons of water. For a 10,000-gallon pool, every 10 lbs of salt raises salinity by approximately 120 PPM.
To calculate dosage manually: (Target PPM - Current PPM) x (Pool Volume in Gallons) x 8.34 / 1,000,000 = Pounds of Salt required.
Why Digital Meters are Better Than Test Strips
Test strips can carry an error tolerance of ±400 PPM. Using a calibrated digital salinity pen gives ±100 PPM accuracy, preventing unintentional over-salting.
