Hey all, I could use some help with the brew water calculator. I live in an area with calcium rich water, and quite high bicarbonate (303 ppm). The full report is: Ca 87 Ma 10 Sodium: 3 Chloride: 3 Sulfate: 4 Bicarbonate: 303. I need to adjust the water for the "light colored and malty" profile. Those stats are: Ca 60 Ma 5 Sodium: 10 Chloride: 95 Sulfate: 55 HCO: 0. My question is: when I click on "update calculations" in the "Water Target Selection" somehow my HCO in the "Actual" row has magically reduced (from 303) to "1.756". My Ca has reduced to 35, my Magnesium to 5, et cetera. I haven't done any boiling or additions of salts. How does this compute? How am I to understand these stats?
