My well water is terrible, so I typically buy water for brewing. Sometimes, if I'm in a patient mood, I will draw 10 gallons out of my fridge which has a filter, and use that, but I usually use Ice Mountain water from the store. Here's their analysis...unfortunately, the ranges seem awfully big to make a good analysis of how to treat. Any suggestions on both what I should add to treat it and also what numbers to base it on? Maybe take the average of the range? Any input is appreciated. I am mostly an ale brewer.
