- 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.

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 30,000 gallon pool
In a 30,000 gallon pool doses run to gallons and bags, so pour or broadcast them while walking along the deep end or in front of several returns rather than in one spot. Larger pools take longer to mix: give the pump at least an hour before you retest.
