How To Lower Salt Level In Saltwater Pool?

Saltwater pools are a great way to relax in this hot summer season and the best place for family reunion parties. To operate any saltwater pool, there is a need for sodium and pool salt, but at the same time, excessive salt can lead to corrosion and other side effects. It is not that easy for your swimming pool to remove sodium easily and make your pool a safe place for relaxing. The salt levels of your pool must be checked from time to time and adjusted to the minimum level. Read the article to learn how to lower the salt level in your saltwater pool.

Checking Salt Level

Most modern saltwater pools come with high-tech control panels that, among other things, allow you to check the water’s overall salt levels. Testing strips are also available to check the salt level in your pool. According to the manual, the strips change color once dipped into the pool and read out the PPM level. If the PPM level is above the recommended level, there is a need to lower the salt level in your pool.

Methods To Lower Salt Level In Saltwater Pool

1. Dilute The Pool

This method can be implemented when the pool is not full, and there is scope for adding more water. Add some fresh water to the pool and use strips to check the salt level. Repeat the addition of freshwater until the desired PPM level is achieved. If the PPM level is not achieved and the pool is full, you need to drain some water.

2. Drain And Refill

Drain six inches of water from the pool and refill it with fresh water. Turn on the pool pump to circulate the water, and retest the salt levels. If you’re still at a higher salt level than you prefer, drain another six inches and refill with fresh water again. This method is a pure trial and error approach, and there is no particular method or formula to determine the amount of water that needs to be drained.

3. Refreshing With Water

This refresh method is a great option when the water level drops naturally. This water drop may be due to evaporation or water splashing after heavy use. When this happens, there will be an increase in salinity level. Before attempting this method, make sure you follow these rules.

  • Test the salt level before starting the process
  • Refill the water with fresh water and let the water circulate for sometime
  • Collect a sample and check the salt level
  • If the level is too high, then drain the water and repeat the steps

How Much Water To Drain?

Once the total volume of your pool is known, then calculate the actual reading of salt level in the pool. Now divide the salt level by the actual level to be maintained, and the value should be equal to one for a perfectly maintained pool. If the value is greater than 1, multiply it by the volume of water in your pool to know the amount of water to be drained to get the recommended salt level.


For any saltwater pool, it is important to maintain the correct salinity level to reduce the pool’s side effects and have a healthy life. For any saltwater pool, using the right pool salt helps maintain the salt level.
