I see your point on the first one. Using CaCl2 instead of NaCl makes sense, so less Gypsum is needed.
MgSO4 would be to bring it to the range of 10-30. No? Doesn't make any difference?
On the second one, without any salts, the mash PH would be 5.06, lower than the recommended range. If I use only CaCl2, that would make it even lower, no?
I used chalk and baking soda to raise the mash PH.
I'm confused about the Mash water and Sparge water volume fields.
I do fly sparge, so I usually add 5gal strike water, mash, then fly sparge until I collect 5gals. I usually heat much more sparge water than needed, so I'm not sure how do I use thees 2 fields.
