Yep, the label on the package showed Weyermanns, as I requested.
The way I've got my water adjustment page setup, my tap water profile is loaded at the top. Then beneath that I have the dilution water profile set to distilled water, 100% dilution. It doesn't carry the nasty bicarbonate from my tap water into the "finished water profile," so I'm guessing everything is setup correctly.
Also, as a correction I used 8.75 gallons of water, not 8.25.
I could still be missing something/inputting something improperly.
