I'm really starting to understand this more and more but still don't understand something. When inputting your water report it has you put in your water pH, on tab 2 where you do your sparge acidification it has you again put in your water pH, now the acid needed for sparge water will change as the pH in tab 2 (Sparge acid) is changed.
Now here is what I dont understand. Why does the mash pH not change or the amount of acid needed to get a desired mash pH change when you change the pH of the water in tab 1 (water report).
