That water is not bad, although without putting this into Brun Water, I suspect the profile is slightly out of balance (cation/anion ratio). You can easily manage that bit of alkalinity with a liquid acid, like phosphorous or lactic. For very soft water profiles, like a Czech Pils, you will want to dilute with RO or distilled water. Of course, I would carbon filter and use Camden tablets to deal with any residual chlorine or chloramines. I have a walk through for Brun Water at my blog if that helps. Accidentalis.com
