Salt Water Pool System FAQs


What is a Salt Water Pool System?
A salt water pool system produces chlorine using electrolysis and the water in your pool.  The chlorine reacts with the water to form hypochlorous acid to sanitize the pool. 

These systems are usually referred to as salt chlorinators because they require salt to be present in the water to operate.  The generator produces the chlorine required to sanitize the pool on-site. 

There is no need to deal with potential hazardous chemicals.  A salt water pool system eliminates chloramines and other chlorine compounds, which are responsible for the side-effects commonly associated with the use of pool chlorine.

How is it different from using chlorine?
Both techniques sanitize the water in your pool in the same way.  It does not matter what type of chlorine is added to pool water, it all does the same thing, create hypochlorous acid.  It is hypochlorous acid that is responsible for sanitizing a pool, the chlorine is just used to create the acid. 

The sanitizer produced by a Salt Water Pool System is measured using the same test kits used for testing chlorine levels in pools, and the chlorine residual can be maintained at required levels by simple adjustment of the generator output.

Will a salt water pool system save me money?
A considerable amount of savings can be realized by owners of commercial swimming pools and spas, water-park pools, water-features and other such applications which require large amounts of chlorine.  Home owners will also see savings due to the smaller quantities of chemicals required.

Is a salt water pool system healthy?
A salt water pool system will maintain perfectly healthy water, while eliminating the risks and problems associated with periods of very high or low chemical levels.  Additionally users of salt chlorinator generators enjoy the natural therapeutic and health benefits of the mild salt water and eliminate the effects usually associated with manually chlorinated water.  Swimmers who suffer from chlorine allergies will find relief from those symptoms in a saline pool.  Other advantages include no irritated eyes, irritated skin, damaged hair, or damaged bathing suits.

How salty is the water?
Ocean water has a salt content of around 35,000 parts per million.  Your threshold for tasting salt is around 3,500 ppm.  Most chlorine generators require a salt content of 2500 – 6000 ppm in the pool.  A typical chlorine generator requires a concentration of salt less than 3500 ppm to operate, which means you will not even taste the salt in the water.  Swimming in a pool with a mild concentration of salt feels like taking a shower in soft water.

Will the salt corrode or damage my pool?
No, the salt concentration is not strong enough to cause corrosion. The water salinity is similar to that of a very mild eye-wash solution.

Will I need to change the water?
In most cases no.  You may need to change the water for other reasons not associated with the generator.  For example if the water is too hard.

Will I need to change my existing pump, filter or heater?
It is not necessary to change any of your existing equipment.

How easy is it to install a Salt Water Pool System?
Installation can easily be done by a handy home owner.  It only takes an hour or two depending on your skill level.  Commercial installations are typically not complicated either, but like any project can become more complicated depending on the layout of the equipment and pipes, or access and space limitations.  If there is a pump and filter, a salt chlorinator generator can be installed.

How often will I need to add salt?
Salt is added to the water at the time of installation.  Evaporation does not reduce the salt level nor is the salt consumed by the salt chlorinator generator.  Only top-up salt is required to make up for salt lost through water splash-out, over flow due to rain, filter back-flushing, or leaks in the pool.

Can a Salt Water Pool System be used in any pool?
A chlorine generates can be used in virtually any pool of water that requires some form of sanitizer to keep the water healthy and algae free.  Hower, there must be some type of water circulation and filtration system present for it to work, and where the condition of the water is required to be maintained at levels conducive to the use of chlorine.  A Salt Water Pool System may not be appropriate where there is a large volume of water or a heavy sanitation load requirement.  

Do I have to worry about the size of the salt chlorine generator?
Salt Water Pool Systems come in a variety of sizes.  You will need to match the production capacity of the generator to your needs. 

How long must the Salt Water Pool System operate every day?
The salt chlorine generator that you purchase must be able to produce the necessary sanitizer within the daily pump/filter operating time.  To reduce utility costs, you may choose to operate your pump and filter for only part of the day.  In most cases the cost to run a Salt Water Pool System is relatively low and the generator can be left on all day.

Does every pool require the same amount of sanitization?
Every pool has a sanitizer-demand that is dependent upon many factors, including water temperature, various water constituents, the number of swimmers, and the daily number of hours the water is used.  The required amount of sanitation is therefore not only based on the type of pool but how it is used.
