Best pool salt – overview

  • Saltwater pools create a softer feel and ease of maintenance.
  • Impurities in salts can stain your pool and make the life of your salt generator shorter.
  • The purest forms of sodium chloride are found in mined salt, classifying it as the best pool salt.

You could choose between saltwater pools and a sweet water pool. Both pools require maintenance and hygienic care to avoid health-related complications. Although public pools use chlorine as a disinfectant, the main reason you return from swimming with bloodshot red eyes and for some even skin irritation and rashes. Saltwater pools use salt mostly and a smaller percentage of chlorine. Saltwater pools don’t create irritation, and instead, the salt content also results in softer hair and skin.

These pools are not as salty as seawater; they have only ten percent of salinity. The saltwater pools have less maintained to compare to sweet water pools and create as velvety feel to water in touch with the skin. Adding salt to the pool can be easy as 1-2-3. All you need is mined sodium chloride salt with high purity and a salt generator. Using the right pool salt to add to your pool is essential. It is vital to the pool’s overall health and chemistry and ensures the longevity of your salt generator device.

Types of the best pool salt

There are many brands and advertised salt in the market. For understanding the bet salt for your pool, you need to differentiate between the types of salt available. The general rule is that the sodium chloride salt must have purity above 95%. Of course, the sodium chloride salt has the same chemical compound as the table salt. Although the difference lies in iodine, table salt is enriched with iodine, which can harm your salt generator, and you should avoid adding it to your pool water. The higher purity of the salt is, your job with your pool is easier. Selecting the best pool salt can help you sustain your pool and prevent damage to your salt generator. There are three main types of pool salt available; solar salt, mechanical salt, and mined salt.

Solar Salt

The method used in obtaining solar salt is one of the most ancient ways people derived salt from the sea. Commercially, seawater is channelized to a clean surfaced area from is exposed to sunlight. The sun evaporates the excess water gradually and dries out the salt. Seawater indeed contains bacteria, but no living organisms can pass through when drying out the salt. The salt itself is known to be an antiseptic agent. The impurities and nonliving organic matter in the sea salt have to be removed by the salt generator. The sea salt is known for its many benefits to the health of the skin, joints, and muscles. However, it has the highest content of organic impurity.

Heated Salt

Heated salt or mechanically evaporated pool salt also uses the sea as its source. The process of pooling clean seawater into uncontaminated areas, but the process takes place much faster. The mechanically evaporated salt uses heating instead of the sun. In addition to having a quicker process to obtain, the heating continues much after the water has been dried out. This heating helps to burn-off the organic matter in the sea salt. This method is more advanced to compare to solar techniques, but the impurities are still high. The mineral content of sea salt is not only sodium and chloride. It also includes other minerals such as iron, copper, phosphates, and so on. The salt generator filters will not be able to filter these other minerals from the pool water. The only issue is with the chemical imbalance created in your pool. When pure sodium chloride dissolves in water, it breaks down into sodium ions and chloride ions. When their other minerals in your salt, you have additional ions dissolved. It can stain your pool’s walls by damaging your salt generator cells. You would require to clean the mineral stains on your pool’s walls.

Mined Salt

This is known as the best pool salt because of its high purity levels. Mined salts are formed in the shape of crystalline deposits in the earth’s layer through millions of years of pressure and volcanic actions. The crystallization process keeps its compound free from organic impurities and other minerals. It is essential to pay attention to a few things while adding this salt to your pool. You must purify and balance your pool water before putting the salt. Add the salt in several does for better dissolution and into the deep end of your pool.


Aside from the beauty effects of a saltwater pool, lack of irritation and ease of maintenance, salt keeps the body more toned and healthy. If you are taking your pool swimming as an exercise, you may want to consider turning your sweet water pool to a saline one. It is best to purchase the salts from an authorized store to receive the purest form of salt.
