Get Pool Salt Calculator

How much salt do I add to a 15,000-gallon (56,800-liter) pool? If we have a 15,000-gallon pool containing only freshwater, we'll need to add about 400 lbs (180 kg) of salt, to achieve the recommended salt concentration of 3200 ppm.

For a newly constructed pool or freshly plastered finish, it is recommended to allow the pool surface to cure for 30 days prior to adding salt (Sodium Chloride = NaCl).

How much salt to add to the pool? To reach the initial salt level recommended by the salt system manufacturer (usually 2,400–3,200 ppm), you will need to add about 200 pounds of pure pool grade salt (NaCl), per 10,000 gallons of water. This dosage will get you to approximately 2,400 ppm salinity.

In that case, You'll need to add 30 lb of salt for every 1000 gallons of water. Therefore, if you have a 20,000 gallon pool and want to determine how much salt you'll need to buy, you would use the formula “30/1,000 x 20,000”, which equals 600. Meaning, the pool would require approximately 600 lb of salt.

How much salt to add to the pool? To reach the initial salt level recommended by the salt system manufacturer (usually 2,400–3,200 ppm), you will need to add about 200 pounds of pure pool grade salt (NaCl), per 10,000 gallons of water. This dosage will get you to approximately 2,400 ppm salinity.

If you're converting to a salt water system for the first time, you'll need about six or seven 40-pound bags of pool salt (for a 10,000-gallon pool). On the other hand, if your salt levels are just low (around 1,000 PPM), you'll only need about four or five 40-pound bags of pool-grade salt.
