While salt water can be generally more inhospitable to bacteria and viruses than fresh water, even if you have the ocean's salt level you cannot and should not rely on salt for any level of sanitation, and certainly not at "comfort" or even SWCG levels. DON'T DO IT!!!!

Salt-water pools simply break salt, which is Sodium Chloride, down to extract the chlorine from it. THAT chlorine is used to sanitize the pool and is exactly the same as chlorine from bleach or powdered products.
