Swimming in a saltwater pool can be a delightful experience. It’s softer on the skin and eyes compared to traditional chlorine pools. But maintaining the perfect salt balance can be a bit of a challenge for pool owners.

That’s why we’ve created this ultimate guide, to walk you through everything you need to know about adding salt to your swimming pool. So let’s dive in!

1. Determining the Right Amount of Salt

The amount of salt you need to add to your pool depends on the pool’s size and the current salt levels. Generally, a saltwater pool requires between 2700-3400 parts per million (ppm) of salt. If your salt levels are below this range, you’ll need to add more salt.

Key Considerations:

  • Pool Size: Measure the length, width, and average depth of your pool in feet. Multiply these three numbers together, then multiply the result by 7.5 to calculate your pool’s volume in gallons.
  • Current Salt Level: Use a saltwater test kit to determine the current salt levels in your pool.

Pro Tip: There are online calculators available where you can input your pool’s volume and current salt level to determine how much salt you need to add.

2. Adding Salt to Your Pool

Once you’ve determined how much salt you need, it’s time to add it to your pool.


  1. Purchase Pool Salt: Pool salt is different from table salt. It’s specifically designed for swimming pools and is usually available in large bags at pool supply stores.
  2. Spread the Salt: Pour the salt directly into the pool, spreading it around as evenly as possible.
  3. Brush the Salt: Use a pool brush to help dissolve the salt and distribute it throughout the pool.
  4. Run the Pump: Run your pool’s pump for at least 24 hours to help circulate and fully dissolve the salt.

Note: Never pour salt into your skimmer or directly into your salt chlorinator cell as it can cause damage.

3. Monitoring and Adjusting Salt Levels

Regularly monitoring your pool’s salt levels is crucial for maintaining the perfect swim environment. Rainfall can dilute the salt, while evaporation can increase its concentration.


  • If your pool’s salt level is below 2700 ppm, add more salt.
  • If the level is above 3400 ppm, you’ll need to add fresh water to dilute the salt concentration.

Remember, consistency in checking your pool’s salt levels will ensure a delightful and safe swimming experience.

Conclusion: Dive into Your Perfect Saltwater Swim

Maintaining the correct salt balance in your pool is key to the health and safety of all swimmers. With this comprehensive guide, you’re now equipped with the knowledge to properly add salt to your swimming pool. So go ahead, dive in, and enjoy your perfect saltwater swim!
