Does it take much change in mineral content to see it clouding up? In the past I have seen it take a week to a month for mine to cloud up, but for the brew session I had on Monday, after six hours my bucket looked like skim milk. As far as I can tell, my water comes from a (Maryland) river and is held in a reservoir till needed. If I could I would tell you the makeup of my water, but the water report I can get online is pretty much useless from a brewing standpoint (no numbers for pH, alkalinity, etc.).
