remineralization, how much? I've read that RO and RODI (And distilled water) can be re-mineralized by using Himalayan Sea Salt (Seems like the safest--more natural). It also is supposed to help with the pH to make it more along the lines of normal parameters. However, too much salt water in the body can be bad since the kidneys work overtime to flush out an excess of salt. How much sea salt could be added to 1 gallon of water safely for remineralization purposes without compromising our kidneys and not "taste" like salt water? I know they can't handle ocean water, which is 35 ppt or so, but how much is too much? Curious.
