Hello all new here. I'm having trouble on the advanced calculator. Trying to figure out water for a stout. It seems no mater what I do I end up with RA around 0 or negative. As far as I know this is not right. My question is when I am making adjustments such as adding cacl or acid, am I supposed to be trying to get the pH in the display down to where I want it? Say 5.4? I have water with high alkalinity and it seems I shouldn't have to go to the extremes that I am to get the pH there. One water I have is: Ca 50 Mg 12 Alkalinity CaCO3 160 I go as is, to cutting 50/50 with distilled to all distilled and still have the same problem with no RA. What am I doing wrong? The stout I'm trying to do is 44 srm.
