Going to pick up the ingredients for this tomorrow. I made it a while back and it was fantastic.
I just finished Palmer's Water book, and am going to build from RO water using the "Amber Balanced" profile in Bru'n Water. My calcium, sulfate and chloride are all higher than in the original recipe, but in the green acceptable range in Bru'n Water. This will be my third batch adjusting water, but the first where I'm adjusting with little knowledge of what's going on, thanks to Palmer's book. The first two times I kind of blindly added CaCl2 and hoped for the best. Wish me luck!
EDIT: After running everything through Bru'n Water and getting the water additions, I read the rest of this thread. The additions Bru'n Water provided are pretty much identical to Yooper's recommended salt additions on p. 10 of this thread.
