If using RO water to build your water profile, is it accurate to list all zeros in the ion concentration cells in Bru'n Water? Is RO really so devoid of minerals that it will get a good result in Bru'n Water if you just assume all zeros?
I think it plugs in numbers for RO water on its own. RO water is not devoid of minerals, but it is low. If you put the dilution of RO water at 100% - it will give you the RO numbers.
Edit - do this on the water adjustment tab.
