pool salt for saltwater swimming pools


Saltwater swimming pools have gained immense popularity in recent years due to their gentle, natural feel and easier maintenance compared to traditional chlorine pools. A key component in maintaining the pristine condition of these pools is pool salt. Understanding its role, types, and application is crucial for every saltwater pool owner.

What is Pool Salt?

Pool salt, also known as pool-grade salt or sodium chloride, is specifically designed for use in saltwater swimming pools. It serves as the source of chlorine through the process of electrolysis, which occurs in a salt chlorine generator SCG or salt chlorinator.

Types of Pool Salt:

  1. Solar Salt: Harvested from evaporated seawater, it’s relatively pure and dissolves easily, making it a popular choice for saltwater pools.
  2. Mined Salt: Extracted from salt mines, it goes through purification processes to remove impurities. It’s equally effective for saltwater pools.
  3. Pool Salt with Additives: Some salts contain additives like stabilizers or anti-caking agents to enhance performance or prevent clumping.


1. How does pool salt work in a saltwater pool?

Pool salt dissolves in water, and through the process of electrolysis in the SCG, it breaks down into chlorine and sodium. The chlorine sanitizes the water and reverts back to salt, creating a continuous cycle.

2. What’s the right amount of salt to add to a saltwater pool?

The ideal salt level typically ranges from 2,500 to 4,000 parts per million (ppm), but check your manufacturer’s recommendations. To adjust levels, use a saltwater test kit and add salt gradually.

3. Can I use any type of salt in my saltwater swimming pool?

It’s crucial to use only pool-grade salt specifically made for saltwater pools. Table salt, rock salt, or other salts contain impurities that may damage equipment or affect water quality.

4. How often should I add salt to my pool?

Salt may dissipate due to splash out, backwashing, or heavy rains. Check salt levels monthly using a testing kit and replenish as needed to maintain the recommended range.

5. Is pool salt corrosive to pool equipment or harmful to swimmers?

Pool salt used in the recommended amounts is generally not corrosive to pool equipment. However, extremely high salt levels can potentially cause corrosion. In proper concentrations, it’s safe for swimmers.


Pool salt plays a vital role in maintaining the chemical balance and cleanliness of saltwater pools. Understanding its types, application, and maintenance requirements ensures a pristine and enjoyable swimming experience while prolonging the lifespan of pool equipment.

Note: Always refer to the manufacturer’s guidelines and consult with pool professionals for specific advice regarding your saltwater pool.
