One of the most exciting advancements in residential swimming pool technology has been the development of salt water chlorine generators.  This type of system works on vinyl and concrete pools but is expecially effective on fiberglass swimming pools and makes them even easier to maintain.  These systems are used as a replacement to an in-line chlorine feeder that sanitises the pool water. But, as with anything ‘new and improved’, there are pros and cons to the products and a few common misconceptions.  Here are a few things to keep in mind when deciding which kind of sanitation to use on your fiberglass swimming pool.


 Chlorine Feeder: Cons

-Uses processed chlorine tablets that dissolve into your pool water

-A manual hand valve is used to control amount of chlorine put into the pool

-Chlorine may cause unpleasant odor, uncomfortable skin and eyes, and faded bathing suits

-Tablets must be added to unit continually throughout the season

Chlorine Feeder Pros:

-Chlorine is being added to the pool as long as filter pump is running

-Unit does not need to be cleaned or serviced throughout the season

Misconception: Chlorine feeders are expensive  because the tablets need to be replaced all the time.

Truth: A typical fiberglass swimming pool owner in the Midwest will spend between $100-$200 for a year supply of chlorine

Salt Water Chlorine Generators: Pros

-Chlorine is produced in its natural state and added into the water.

-No detectable taste, odor, or discomfort on skin.

-Chlorine level is controlled electronically


-Salt level in the pool must be maintained within a certain range in order for unit to produce chlorine

-Cell must be acid washed several times a year to remove mineral deposits

-Chlorine is only produced when pump is in high speed

-Cell can deteriorate over time and will need to be replaced

-Stabilizer must be added to pool water to help prevent chlorine burn-off from sunlight

Misconception: Chlorine generators provide a completely automated system and no other chemicals need to be checked in the swimming pool.

Truth:Even though chlorine is produced by the cell, all other chemicals- pH, Alkaline, Stabilizer etc- need to be tested and regulated manually.

The decision is ultimatly up to the customer to decide.  We at Signature Pools highly recommend salt water generators to our clients because of the ease of use and resulting water condition of the pool.  However, these systems are not for everyone and do not replace the need for regular chemical checks.  If you have any questions about chlorine generators or in-line feeders, please feel free to contact Signature Pools and Spas at 630.845.1145.
