I have recently decided to go down the rabbit hole of water chemistry. I am using the Bru n Water spread sheet to help me reach my numbers and to help me add the right salts. My question to you all is a simple but potentially not so simple. When adding the brewing salts, do you add it all to your total brewing water (including the mash and sparging water)? Or do you split it between the mash and add the rest to the sparge water? Details on this are highly appreciated! Thanks guys!
