How to Figure Out How Much Salt to Put in a Pool


Saltwater, or saline, pools are an alternative to traditional chlorine pools. Instead of keeping bacteria and algae away by using a lot of chlorine---which smells, burns your eyes and can be hard on your skin---a saltwater pool system actually creates its own healthier chlorine. To make sure your pool works properly, figure out the right amount of salt to put in the pool. If you keep the level too low, the system will not be able to make chlorine; if you keep it too high, you may damage the pool.

Step 1

Know the volume of your saltwater pool. The amount of salt the pool needs is based on the volume. Most pools require a salt concentration of around 3,000 parts per million.

Step 2

Look at the salt level indicator on your saline pool system. Subtract the number you see on the screen from the 3,000 parts per million your pool should have, which will give you the amount of salt the pool needs, if any.

Step 3

Add the amount of salt indicated on the salt container, based on what your pool needs. A chart on the label shows you the amount. Stir the salt in with the pool skimmer until it has dissolved. Do not recheck your salt level indicator immediately, as the system takes time to readjust and make more chlorine. Check back in 24 hours to see if the salt level is correct.

Tips and Warnings

  • Don't swim in a pool with extremely high salt levels.
