added 14 cups of cold water after boil measure before adding them about 24 oz of 1.120 specificy gravity
Based on boiling 1.50 gallonsliters at 1.043 for 0 minutes, this will decrease your wort by 0.00 gallonsliters, bringing your after boil OG to 1.043. You were planning on an OG of 1.043 so you are right on track. Nice job!
