CD Ozone Generator Pool Systems Beat Salt Chlorinators

The salt chlorine generator has been the alternative pool sanitizer of the moment for the past few years because chlorine is continuously generated so owners don’t have to dose the pool, and many people like the feel of salty water. However, pool owners are beginning to see that it has a significant downside.

  • Salt generators replace industrial chlorine with… locally made chlorine. All chlorine introduced into the pool, by ANY method, makes hypochlorous acid. The problems with chlorine remain, although at a less intense level.
  • One important implication of this is that you have to maintain the pool chemistry just as carefully with salt generators as with any other form of chlorine – the chemistry balancing act is just as hard with salt.
  • Salt creates a disposal problem.
  • Salt is corrosive. Over time it can damage surfaces surrounding the pool, requiring expensive repairs.

Salt Water Pools Are Old News

The saltwater pool fad began in Australia at least 25 years ago. The convenience of having the chlorine needed to sanitize the pool generated at the point of use is an undoubted benefit. When the salt chlorinators are working properly (meaning they are properly sized and installed, and regularly cleaned), they can maintain a low level of chlorine in the pool continuously. As a source of residual chlorine, they can function adequately.

However, as the primary sanitizer, they also create negative side effects. Salt build up creates a disposal problem. And the salty water can have corrosive effects on pool decks and equipment. If the chlorinators run at too high a level, the problems with chlorine itself can emerge.

Ozone as the Primary Sanitizer

When a pool ozone generator, properly sized and installed, is used as the primary sanitizer, a salt chlorine generator running at low levels to produce a supplemental chlorine sanitizer can make for an excellent system. The combination of ozone and a low level of background chlorine creates a healthy, good feeling pool without the side effects of salt and chlorine.
