Possible advantages of salt water pools over chlorine pools is the lower volume of irritating chemicals, which produces less eye, skin and respiratory irritation. Salt water also reduces maintenance cost and effort, and reduces risk of environmental damage from leaks and spills. Salt water pools, says Wright's Pool Service, offer some advantages over chlorinated pools, including a lower lifetime maintenance cost than chlorinated pools and less risk of damage to fabrics and bathing suits that come into contact with salt water.
Salt water pools work by dissolving salt tablets into water. They use some chlorine for the purpose of sanitation and disinfection, especially with the first round of salt water. For many people, says Wright's Pool Service, one of the benefits for salt water pool owners is that those pools are easier and more cost-effective to maintain. The initial cost of switching to a salt water system may exceed the cost of installing a chlorinated pool. However, lifetime maintenance fees for salt water pools is lower, as salt never entirely disappears from pools.
Salt water pools use some chlorine, but only in minimal amounts. This lower chemical base puts less stress on hair, skin and eyes. Salt water is also easier on pets and animals. Despite the increasing popularity of salt water in pools, chlorine is still the most common additive to pool water. This is particularly true of commercial pools, where chlorine is essential for eliminating bacteria and pathogens.
