I think I already know the answer. First my water is about 350-400 tds. I have looked everywhere for di water but with such high tds it doent seem worth it $$$. I have been looking into a ro machine, guy says he can get it down to about 10 or under, but with a different membrane I'll get alot more flow but tds will be around 35-60. So at what tds will water start leaving spots, think I read once around 10. Does anyone have a truck mount(portable) ro machine?
