Morton does not recommend adding pool salt to a pool without a chlorine generator. Adding pool salt to a pool not equipped with a salt chlorine generator will not generate the free chlorine agents necessary to maintain a safe swimming pool environment.

You should only use pool salt if your pool is equipped with a functioning salt water chlorinator or generator system. If you are unsure if you have a salt water system, please consult your pool installer or a pool professional to confirm.

Morton® Pool Salt does not contain any anti-caking agents.

Morton® Pool Salt does not contain iodine.

Chlorine is a necessary agent to maintain a safe swimming pool environment. Chlorine not only disinfects water, it reacts to kill disease-causing organisms such as bacteria, algae, ammonia and other organic matter that can be introduced into a pool system over time. Traditionally, liquid chlorine has been used to introduce necessary chlorine agent into a pool system. While liquid chlorine works well functionally, it can lead to many negative side effects on hair, skin, eyes and clothing which are not ideal. Today, pools equipped with a salt chlorine generator system or automatic sanitizer system ( a.k.a. salt water pools), can perform the same function but without the negative effects.

When pool salt (NaCl) is dissolved in a salt water pool, the salt chlorine generator system or automatic sanitizer system electrolyzes the salt and transforms the chloride (Cl) portion of the salt into chlorine. This chlorine dissolves in the water to perform the same functions as conventional liquid chlorine used in pool maintenance. However, unlike traditional liquid chlorine used in pool maintenance, salt chlorinator systems generate “free” chlorine as water passes through the electrolytic cell which destroys chloramines responsible for “chlorine odor”, red/irritated eyes, bleached/green hair and damaged bathing suits.

After starting up your pool and achieving optimal salt levels, you will only need to add salt when necessary as salt levels in the pool decrease (typically due to leaks, rainwater overflow, splash-out or filter backwashing). The amount of salt you will need to add depends on the starting salt level of the water. Please contact a pool professional if you have any questions or concerns about maintaining your salt water pool.
Note: normal water evaporation will increase the concentration of salt in pool water. You will need to add “make up water” to bring salt concentration back to target ppm levels.

Morton® Pool Salt is made of high purity salt (sodium chloride) designed to maintain salt water pools.
