Pool Salt Calculator

This calculator determines how much salt to add to your saltwater pool to achieve the optimal salinity level.

Formula Used:

Salt Needed (lbs) = [(Target ppm - Current ppm) x Pool Volume x 8.33] / 1,000,000 x 120

Optimal Salt Levels:

• • Standard pools: 3,000-3,500 ppm
• • Most salt generators: 3,200 ppm (ideal)
• • Maximum safe level: 4,000 ppm

Important Notes:

• • Use pure pool salt (sodium chloride)
• • Add salt gradually over 24-48 hours
• • Test salt levels after each addition
• • Run pump for 24 hours to circulate
• • Salt doesn't evaporate - only water does

Safety Tips:

• • Never add salt while people are swimming
• • Dissolve salt in bucket before adding
• • Brush pool bottom to prevent staining
