Adding Salt to a Pool with a Salt Chlorinator



When adding the initial dose of salt to a pool, there will be hundreds of pounds of salt going in all at once. It is important to add the salt evenly around the entire pool to ensure that it mixes quickly into the water. Lightly brushing the salt will help it dissolve more quickly. Don't let the salt sit in large piles at the bottom of the pool (small amounts are OK). Let the filter system run continuously for 24 hours to allow the salt to completely mix into the water. Leave the salt system turned off for this mixing period.

How much salt to add:

Always add one or two bags less than what is required. After it mixes in, test the salt level and add what is necessary to reach the final level. If you add the full amount and end up with too much, you will have to drain some water out of the pool to remove the excess salt.
