A Dive into Pool Salt: What You Need to Know

When it comes to saltwater pools, salt is the key ingredient for keeping your pool safe and clean. However, not all salt is created equal. The type and quality of salt you choose can significantly impact the health of your pool and the effectiveness of your pool’s sanitization process.

Salt is not just a staple in your kitchen; it’s also a critical component for many swimming pools. The rise in popularity of saltwater pools has created a demand for high-quality pool salt. Why the shift to saltwater? Not only can it be a more cost-effective way to keep your pool clean, but it’s also gentler on the skin and eyes, and is less likely to cause the kind of irritation often associated with heavily chlorinated water.

Types of Pool Salt: Mined Salt, Solar Salt, and Mechanically Evaporated Salt

The three primary types of pool salt are mined salt, solar salt, and mechanically evaporated salt.

  1. Mined Salt: Also known as rock salt, mined salt is recognized for its high purity level, containing between 95% and 99% sodium chloride. This purity makes it a great choice for sanitizing saltwater pools. Moreover, the larger crystals of rock salt mean it lasts longer in the pool. However, the high sodium chloride concentration can cause corrosion in concrete pools. Plus, some rock salts may contain trace minerals and iron deposits, which can cause staining.
  2. Solar Salt: Solar salt is made by drying saltwater under direct sunlight. Although it’s a natural process, solar salt may contain microscopic aquatic life, like brine shrimp. Over time, these organisms decay, leading to organic matter that is not ideal for pool water. Despite its organic contaminants, solar salt is an affordable option and effective at producing chlorine.
  3. Mechanically Evaporated Salt: This type of salt is produced by using heat generators to dry out seawater. It’s similar to solar salt, but the mechanical drying process helps remove organic contaminants. However, this method can leave behind mineral deposits that may cause scaling in your pool.

Choosing the Right Pool Salt: What to Consider

When choosing a pool salt, it’s crucial to select a product specifically designed for swimming pools. This ensures the salt is of the highest purity, minimizing the presence of unwanted organic contaminants, minerals, and metals. A purity level of at least 95% sodium chloride is recommended for saltwater pools.

High-purity pool salt not only results in cleaner pool water but also reduces maintenance needs and extends the life of your salt cell. Remember, the cleaner the pool salt, the less the chlorine generator and salt cell need to work.

How to Use Pool Salt

Properly adding salt to your pool is critical for optimal performance. Generally, you should distribute the salt over the greatest water surface area possible to ensure a fast dissolve rate. Always follow the manufacturer’s guidelines for quantity and frequency of adding salt. Avoid piling the salt on the pool surface and brush as necessary until fully dissolved.

Maintenance Tips

Maintaining a saltwater pool requires regular testing of the water to ensure the salt levels are appropriate. If the salt level is too high or too low, it can affect the efficiency of your salt chlorine generator and the quality of your water. Be prepared to adjust the salt levels as necessary, and don’t forget to regularly check the pool’s pH levels, as well.


Q: How often should I add salt to my pool? A: This largely depends on the frequency of pool use, rainfall, and the amount of backwashing performed. Regular testing will help you determine when additional salt is needed.

Q: Can I use table salt in my pool? A: No, table salt often contains additives like iodine and anti-caking agents which can interfere with your pool’s chemistry and potentially cause damage to the pool equipment.


Choosing the right salt for your pool can significantly enhance your swimming experience. Considering factors such as the salt’s purity, dissolving speed, price, and the reputation of the brand can help guide your decision. Among the options we’ve reviewed, the AQUASALT 40 Swimming Pool Chlorine Generator Salt stands out for its fast dissolving time, high purity, and reasonable price.
