How often do I need to add salt to my pool?

There is no set timeframe of when you need to add salt to your pool. Because salt does not dissipate from your water, the only time you would add salt to your pool is when you add fresh water or after heavy rain that dilutes salinity levels. An example of when you would add fresh water is after a heavy backwashing cycle.
Take a look at our guide on adding salt to your pool: How to Add Salt to Your Pool
A helpful tip for adding salt to your pool: add the fresh water first, then measure your salinity levels to determine how much salt should be added to your pool. After the freshwater has been added, test your water either by reading your salt chlorine generator’s control box, taking it to a local
pool, or use a home saltwater test kit.
Once you have the salt levels noted, consult your owner’s manual’s salt chart to determine how much salt is needed to raise your pool’s water levels. The picture to the left is an example of a salt-to-gallons chart found in the Hayward AquaRiteliterature. If you need help estimating gallons, use this pool volume calculator.
