I purchased an R/O setup from J&L and a tds meter. I had a normal filtering system for my fish water, I found that it was reading in the 120 mark, my NW Cal tap water was 155, now our drinking water we bought from COOP (Culigan) and it read in one bottle 55 and another purchased a week later 38. I found rain water in my back yard to be 7. My r/o sys. puts out consistent water at 1. Just so you know when water has a 0 tds it doesn't have a taste (tasteless) anything added to water changes that. Just from my experience and my .02 worth on the H20.
