I'm still trying to figure out what happens to the salt in my pool. My understanding so far is that the salt is broken down by the SWCG into its more basic constituents, one of them being chlorine gas which is dissolved into the water. After the chlorine is used to sanitize the water by oxidizing bacteria and other pathogens I think I understand that it somehow reverts back to salt again. What I'm confused about is what type of salt; the same sodium chloride that I poured in to begin with or something else? Is the residual salt used over and over to generate chlorine? What happens to the salt eventually to lower the salt level in the water? Is there some form of salt left over that builds up over time that isn't used to liberate chlorine? If so, do I eventually have to do a partial drain and refill to remove the salt residual?
Thanks for clearing this up for me,
