I have a salt system...works great. But I'm thinking about changing over to a UV system. The salt system generates chlorine from the salt, then the chlorine turns back into salt and is regenerated over and over. And the salt level is so low that you can't even notice it in your pool...it's not like swimming in the ocean or anything.
But the UV systems don't make chlorine at all. Matter of fact there is NO chlorine involved in any manner. It's simply a UV light inline with the plumbing from your pump. And it's tuned to kill all the bacteria and algae, etc. in the water. It's the system that is used now for the Olympics. No chemicals at all.
