So I have decided my best bet to deal with my local hard water is to dilute with RO. However, a Ward labs report was not done since my area says they change water supplies on an as-needed basis. 2 of the 3 sources are hard, so I am rolling the dice with the numbers I was able to pry from them. I was not able to get a calcium count, but did get a hardness value of 180, and alkalinity (as CaCO3) of 250. Is there a way to figure roughly what kind of calcium I am looking at, so that when I do a 1:2 tap/RO dilution I know if I need to be adding any calcium back?
