What Is Salt Water Chlorinator?

Also known as salt chlorine generator. It is one of the most cost-effective and eco-friendly methods to keep your pool water clean and clear. A pool chlorine generator is your helpful assistant in maintaining and cleaning pool water. This device works by converting the salt,( which you have added into the pool) into an active form of chlorine, which then sanitizes the pool. This means you don’t have to add sanitizing agents by yourself. Just add a bag of salt to your pool and salt water chlorinator will convert the salt into chlorine. All you have to do is to make sure that the pool pump is running. The pool will be sanitized constantly provided the pool pump is running.

How Does Salt Water Chlorinator Works?

The pool chlorine generator works cyclically. When you pour a bag of sat in your pool, connect the chlorinator and turned on the pool pump. The salty pool water will enter into the main compartment of the chlorinator that is the cell. A cell consists of parallel titanium plates which are coated with ruthenium and iridium. And here the main process takes place. All the salt has now been converted into hypochlorous acid via low voltage current that has been sent by the control box to the cell.

The process is called electrolysis. This chlorine gas runs throughout the plumbing system of the swimming pool, thereby removing and destroying algae and bacteria. At this step, the pool and the plumbing systems are now sanitized. After the sanitization process is completed, the chlorinator will convert the chlorine gas to chloride and combine it with sodium so that it becomes salt again.

Turning the pool’s pump on and off is a big hassle. And if someday you forget to turn it off, the result would be quite horrible. So to avoid such a situation, we always recommend looking for chlorinators that have a built-in timer in them. Chlorinators with timers are a big blessing as they will automatically turn the pool’s pump on and off.

Auto Clean:

Maintaining a clean and clear pool is a big job indeed. Along with it, if you start cleaning chlorinators, then the job would be double.

This way, it saves your time.

Other Attractive Features:

Above mentioned features are the basic features that you have to look for while buying a salt water chlorinator. But if you find some chlorinators with other attractive features such as winterize mode and chlorine-boost mode. Then immediately grab that chlorinator.

Let me tell you, with winterize mode your chlorinator will remain protected from freezing temperatures whereas, in chlorine-boost mode, the system will release extra chlorine into the water.


How long do salt chlorine generators last?

It all depends upon the size of the pool and the longevity of cells. If you have a small pool with high-end salt water chlorinator chances are that it will last long. Usually, the cell will last up to 7 years easily.

What are the cons of Chlorinator?

There are few disadvantages of the chlorinator. Such as, it’s hard to find replacement parts and if you find, then they are quite expensive.

Does salt water system work fine with all types of pools?

No. with vinyl liner pools that have metal wall panel, chlorinators are not advisable. The salt will for sure corrode the panels and other stuff made with galvanized steel. Whereas, you can fearlessly use it with fiberglass pools, vinyl liner pools with polymer wall panels, and concrete pools with a tiled interior surface.

How much salt does my pool require?

For this check the chlorinator manual to see the recommended amount of salt.

What kind of salt does a chlorinator use?

You can add the following types of salt:

·       Solar salt (organic impurities)

·       Mechanically evaporated salt (mineral impurities)

·       Mined salt

Always use those salts that are intended for swimming pools such as food-grade, granular and non-iodized salt.

Can we use rock salt?

A big no. rock salt is not pure enough to it won’t dissolve well. Its recommended to use 99% pure salt.


Chemically added chlorine is not eye and skin-friendly. Chlorine combines with the bacteria in water and becomes chloramines which are responsible for skin and eye irritation. Luckily, salt water chlorinators add hypochlorous acid which is a weak acid and disinfect the pool properly without making any bond with bacteria. Salt water chlorinators are the biggest hack of today’s world to get rid of itchy eyes and skin.
