Why You Should Wait To Swim After Adding Salt To Your Pool

Adding Salt To Your Pool

Swimming pools, whether chlorinated or saltwater ones, need regular maintenance. Performing maintenance in saltwater pools may be higher compared to the chlorinated pool.

It’s because of the chlorination system that requires installation. But over time, you’ll realize that it’ll help you save money.

Can you swim after adding salt to the pool? Experts say that you need to wait at least 20 minutes to 1 hour before going back to swimming. It is to ensure that the salt is completely dissolved and has circulated.

As you read on, you’ll learn that super chlorination may take time to finish. Even if it will not harm you after adding salt, it is still better to wait for it to dissolve.

Adding Salt To Water May Take Upto 24 Hours

Adding salt to the pool is easy. But the real thing is that the waiting time for it to dissolve. Though there is no specific study that supports this, most saltwater owners said it’s the best.

They say that for salt to dissolve, you need to let it circulate through the main drain. And they say that the more you use a finer grade of salt, the faster it will dissolve.

There are also pool owners who suggest you go back swimming even after adding salt into the pool. As long as the free chlorine levels are okay and you see the pool’s bottom, swimming is okay.

They recommend that it’s best if you read the manufacturer’s manual for instructions. And that there are test kits you can use to test the water’s essential chemicals.

Procedures On How To Add Salt Onto The Water

  • Know first what level of salt chlorine generators work in your pool. You can refer to the salt generator manual.

  • Next is to determine your pool’s salt current level. If your pool is newly installed, the salt level must be at 0 ppm. If you are converting to a standard chlorinator, the salt levels must be at around 500 ppm.

  • Using a saltwater test strip, measure your pool’s current level. You can as well bring a water sample to pool stores for them to verify the salt level. Don’t worry as it is free of charge.
  • To know how many pounds of salts you will be using to reach the 3500 ppm, you’ll need some calculations. You can get it by calculating how many gallons there are in your pool. Then you can add salt by using the salt table guide.

  • Pool Stores owners recommend using salt with 99.8% pure sodium chloride or (NaCl). Recommended salts are food-quality, evaporated, granulated, Non-iodized salt. And avoid using salt that has an anti-caking agent like sodium ferrocyanide. It is because it might cause discoloration of the pool surface and fittings.

  • First, turn off the salt chlorine generator at the control unit before adding salt to the pool. It should turn on when the salt is completely dissolved. And click the Pump On option to help dissolve the water and the circulation of the water.

  • Remember that when you add salt and be sure not to add the salts into the skimmer directly. If you want the best results, you can pour it at the shallow end of the pool.

  • When the salt has dissolved, and you can now turn on the salt chlorinator. Then check if the salt level is around 3500ppm. If it’s at a low level, you can reduce the efficiency of the generator. And if it’s at a high level, you can reduce the cell’s life.


To summarize, the waiting time before going back to swimming after adding salt to the pool isn’t that long. Though it’s not mandatory, it is recommended by most pool store owners.

It’s not for your safety, but for everyone’s safety too. And to make sure that you correctly added salt, you need to follow those simple steps.
