Over the past several years, there has been an increase in the use of salt chlorine-generation systems in residential pools. Unfortunately for many of those pool owners, the salt-systems have caused extensive and costly damage, and not just to their pools.

Why is the use of liquid chlorine to sanitize a pool better than chlorine produced by a salt-chlorine generator? Isn’t chlorine all the same?

• Injecting liquid chlorine (sodium hypochlorite) does not increase the pH of pool water as much as a salt-chlorine generator will. The salt chlorine-generation process also produces caustic soda and hydrogen gas. The hydrogen gas eventually dissipates from the water, leaving the caustic soda to increase the pH.



• Injecting liquid chlorine does not cause degradation to pool equipment, coping, water features and the surrounding pool hardscape. Salt-chlorine generators cause these and other problems due to salt corrosion.



• Injecting liquid chlorine does not produce stray currents, which can lead to plaster discoloration, metal corrosion and in some cases, shocks to bathers. A salt-chlorine generator essentially runs the pool water through an electrified grid to produce the chlorine, and salt water is more conductive for any possible stray currents.

There has been on-going discussion in the pool industry, the media, and within local municipalities about the detrimental effects of salt chlorine generators, not only on swimming pools but also on the environment. Learn More
