(BPT) - Pools are great fun for kids and adults and when it is hot in the summer time or you’re on vacation, there is no better way to cool off. Most pools do require a lot of work to keep clean however and there is always that chlorine smell and the burning sensation that affects the eyes and skin. For many people it is the memory of the chlorine that is inescapably associated with all pools.
But for kids today this memory is quickly becoming a non-event thanks to the increasing popularity of saltwater pools.
Saltwater pools work by converting salt to chlorine using an electrolytic converter. This produces the same type of bacteria-killing chlorine found in a traditional pool, but in a radically different fashion. Since the salt generator is adding chlorine to the water at a constant rate, it is capable of displacing the bad smell and burning irritation we normally associate with chlorine and maintaining the right amount at all times.
As the water exits the converter and enters the pool, the sanitizing chlorine eventually reverts back to salt, and the process repeats itself, conserving salt and keeping sanitizer levels balanced. However new salt does need to be added occasionally as salt levels can drop due to splash-out, rain and filter back-washing. Pool owners still should test weekly for pH and chlorine and monthly for other water balance factors.
Saltwater pools require far less maintenance than traditional pools and are much less expensive to maintain as pool salt is far cheaper than traditional chlorine. This is a big reason why so many hotels and water parks in the United State have already made the switch. Plus when it comes to initial construction and installation, the additional cost of an electrolytic converter is very small and easily made up in maintenance savings. Even converting an existing chlorine pool to saltwater can be paid off quickly.
Saltwater pools are certainly not new. The technology started in Australia in the 1960s and today over 80 percent of all pools there use this system. In the United States, saltwater pools first began to see use in the 1980s and today have grown exponentially in popularity. According to data published in Pool & Spa News, today there are more than 1.4 million saltwater pools in operation nationwide and an estimated 75 percent of all new in-ground pools are salt water, compared with only 15 percent in 2002.
Some may be concerned about the effect of salt on pool equipment, construction materials, decks and surrounding structures. However the actual amount of salt used is very low, less than .01 as salty as sea water. You may be able to taste the salt in the pool, but much less so than you can taste and feel the chlorine in a standard pool. When pools are properly constructed and normal maintenance is followed, salt water has no effect on pool finishes, equipment and decks.
Since the Evergreen Commons senior center in Holland, Mich., converted its 65,000-gallon pool to salt water, members have been pleased with the results. "The minute you walk into the pool area you notice a big difference," says Jodi Owczarski, the center's community relations director. "There is no longer that chemical smell. People also tell us that the water is much softer. In the old pool, people said they sometimes had to wash twice to get all those chemicals off, but in this pool, they only have to wash once. All in all, people have been thrilled with this new system."
