    you sure its not RO water? RO is pure water you have to treat with salts and acids to get a true mixture for the right beer, AO is alkaline water or store bought water

    took a while to find the site I found it on.
    it was on Brewtoad.com the name of the beer is Oktoberfest II.
    Maybe the guy that posted it was thinking of R0 water, I don't know.
    I didn't use this recipe.

    here is the site.

    yes he "Treated 7.5 gallons of RO water with 8 grams CaCO3, 1 gram CaSO4, and 1 gram NaCl", that is normal for building your own water

    Russ, you likely won't need the treatment here. I can't remember if you're using Aurora water or are on a well. If you're using Aurora water, for that color of beer, you'll need some calcium - our water is always deficient in it. But not much else. Maybe 6 grams of calcium chloride.
