I remember a post somewhere by AJ deLange, talking about the amount of alkalinity removed by RO systems at home. I can't find it now! I know that the RO system doesn't remove everything, so I was thinking if I could estimate the probably result then I wouldn't have to send in my treated water to Ward Labs.
I do have an aquarium hardness test kit, so I was wondering if I can use what I know from my water chemistry prior to RO filtering and testing the end water to guestimate my alkalinity before I brew today.
