The Popular Salt Water Pool Option
Salt Chlorinator versus Chlorine Chemicals
All pool water needs some form of sanitization. Without it, the pool would be overridden with algae in a matter of days. Sanitization can happen in two ways: By adding expensive, dangerous chemicals or through a natural salt water chlorination device. You can choose to add chemicals such as chlorine or use an automated salt water system that generates its own ultra-pure sanitizer and makes the water more comfortable.
The Salt Water Chlorinator
In 2002, only 15% of new pool installations were salt water. Today, an estimated 70% of all new pools are being built with salt water chlorine generators and the nation has more than 1.3 million salt water pools. It was introduced to the swimming pool market in the 1970's in Australia and has been gaining popularity ever since.
Why has the salt water pool become so popular?
- Swimmers love the soft, silky feel of salt water.
- There is only 1 teaspoon of salt added per gallon of water, so it is virtually undetectable.
- Salt water is gentler on eyes and skin compared with traditionally sanitized pools.
- The pool water is constantly "shocked" as it passes the salt water cell, so the need for shocking the pool with harsh chemicals is virtually eliminated.
- The average savings are $400 per year on chemicals such as chlorine and shock.
- Salt water pools are infinitely easier to maintain.
Who doesn't like salt water chlorination systems?
- Pool builders who don't understand the system and haven't been certified by various salt water chlorination companies like Southern Poolscapes has. If a pool builder tries to talk you out of salt water, you really need to question their technical understanding of the system.
- Pool retailers, whose sales of higher-margin chemicals have been replaced by inexpensive, low-margin commodity salt.
Some interesting facts about salt water pool systems:
The salinity of the human body is around 6000 ppm. If the body is placed in fresh water, osmosis occurs through our skin and eye membranes which is irritating and a cause of discomfort. The effect of this is much reduced in a salt pool because the osmotic effect through our biological membranes is reduced. The ocean has a salinity level of 35,000 ppm, while a salt water pool is only 3400 ppm. And since the salt level of the pool is about ½ of the human body salinity level, the salt is virtually undetectable (except for the lack of shriveling skin and red eyes when you are in a salt water pool!)
