Salt Water Pools vs Chlorine

Does Salt Mean Chlorine Free?

One of the  biggest misconceptions about salt water pools is that they are free of chlorine. Salt is unable to sanitize a pool as is sometimes believed.   In fact, salt is converted to chlorine through electrolysis.  The salt cell (chlorine generator) is used to produce hypochlorous acid (HClO) and sodium hypochlorite (NaClO), which are the sanitizing agents already commonly used in swimming pools. Therefore, a saltwater pool is not actually chlorine-free; it simply utilizes a chlorine generator instead of direct addition of chlorine.

The good news is, there is an advantage to salt over straight chlorine.  The cell that is used to generate the chlorine from the salt helps maintain a constant level of chlorine.  If you are maintaining your own pool that does not have a salt system, or a chlorine injector, you are probably accustomed to dumping straight chlorine in your pool to get content levels to where you want them.   With a salt system, the salt cell is constantly converting salt into chlorine at a relatively consistent rate.  Furthermore, the salt generator means you no longer have to purchase chlorine, store it, or handle it.

Is a Salt Water Pool Maintenance Free?

Although pools with a chlorine generator are easier in the sense you no longer have to lug around chlorine and poor it directly in the pool, there is still considerable maintenance to consider.  You must still be diligent about maintaining the chemistry of the pool.  Therefore, you must still maintain proper levels of salt, and salt water pools often require adjustments to the PH by adding muriatic acid.

In addition, most salt system manufacturers suggest a maintenance schedule of every 3 months where the cell is removed and given an “acid bath”.  This helps reduce the mineral deposits from collecting on the cell, rendering it unable to produce chlorine.  Regardless of these procedures, the cell must be replaced eventually anyway, at a significant cost.

What If I Already Own a Salt Generator?

There has been a large push for salt systems in the pool industry.  Pool owners have been lead to believe that the installation of a salt system will mean that their pools will be chlorine free, and therefore healthier. The advantage of a salt system is the convenience of having chlorine generated right on site, saving carting loads of chlorine from the store to poolside.  In addition, although the water feels softer and gentler on our skin, there is a high level of saline that is present.  This can cause significant corrosive issues for pool equipment.

If you have a salt water system already, there is no need to eliminate it completely.  The addition of our UV pool system will allow you to dial the chlorine generation back to drinking water standards.  This will not only serve to reduce the chemical content of the pool, but it will greatly extend the life of your salt cell.
