I just cant figure this out. I brew an all grain 5.5 gallon batch (into the fermenter) I set up my Recipe. Then I go into the Mash Chemistry and Brewing Water Calculator. I set my water volumes using a calculator from More beer and by experience since for the life of me i cant seem to get the water volumes to work with in BF. The over all volume is set at 10 gallons and that usually works out to be true. I then do all my salt additions and work till i get everything in the green Normal range I save the water chemistry. then I go into the recipe and save. But when I return to the water chemistry calculator the water volumes change and this throws off the salt additions in to the red? I must be doing something wrong?
