Ok so since I do a lot of lighter color beers I am usually adding lactic acid in to drive my PH down. Now my question is doing this also kills my Bicarbonate levels. I have been adding chalk to end of boil but, I just had question to make sure I am doing it right on my Brunwater spreadsheet. I add in the right amount of lactic acid to get my PH in range. Then I go back and take out the acid and plug in the amount of chalk I will add at end of boil to get my bicarbonate levels right. Am I doing this correctly?
With my water I am using way more acid to drive my PH levels down then it tells me too. I might start mashing with less water to get PH down naturally.
