Our water comes into the house softened so I have no choice. I have a Brita filter but still, depending on the style I'm brewing buy RO water from Walmart or Copps for 0.37 a gallon and dilute 1:1 up to 3:1.
Then add calcium sulphate or calcium chloride or both for IPAs along with sour malt for PH. Read the Primer on this forum. Pretty good and makes sense.
