I have soome pretty hard water so I'm doing an 18 gallon batch of cream ale, 4.4 SRM tomorrow. Built the water from 100% RO to get -51 RA. (from Palmer) I went to Palmers spread sheet and built the same, but noticed it didn't say anysthing about sparge water additions. Inserted the Palmer numbers into EZ, and EZ stated I needed to add 3g Gypsum, 7g CaCl, and 4.3 Epsom to the boil. Which of these is correct? I also noticed that when I dilute my sparge water 50% with my water it didn't chage any of the additions to the boil, but did change the totals in the water. Any harm in diluting the sparge 50% with my water, HCO3 169, CaCO3 139,
total hardness 215?
Thanks, My first time building 100% RO
Are You Going to Drink all That?
