How much salt for a 10,000 gallon pool

A 10,000 gallon pool needs 269 lb (122 kg) of pool salt to go from fresh water to 3,200 ppm, about 6.7 bags of 40 lb. Each 1,000 ppm takes 84 lb. Check your salt cell’s manual: most want 2,700 to 3,400 ppm.

Raises salt from 0 ppm to 3,200 ppm in 10,000 gal. That is about 6.7 bags of 40 lb.

  • Brush the salt around until it dissolves, and keep the salt cell off for 24 hours.
  • If you are unsure of your volume, add about 80% first, circulate for 24 hours and retest.

Check the product label. Strengths vary by brand, so enter the % printed on yours. Add one chemical at a time, into the water, and never mix chemicals.

Save this test and get reminded when it is time to retest.

About salt

Use plain pool salt, at least 99% sodium chloride, with no anti-caking agents or iodine. Pour it in the shallow end, brush it around until it dissolves, and keep the salt cell off for 24 hours so undissolved salt doesn’t reach it.

Too much salt only comes down by replacing water, so add about 80% first if you are unsure of your volume, wait a day and retest with a salt test or your cell’s reading.

Dosing a 10,000 gallon pool

That is about the size of a 21 ft round × 52 in above-ground pool (about 9,930 gal), or a 15 × 30 ft oval × 52 in above-ground pool (about 10,130 gal), or a 12 × 24 ft in-ground pool averaging 4.5 ft deep (about 9,690 gal). 10,000 gallons is a typical backyard pool. Measure the volume once rather than trusting the builder’s brochure: an error of 20% in gallons makes every dose 20% off. The pool volume calculator takes a minute.
