@mabrungard I'm using Bru'n Water 5.5 for my next beer, an all grain wheat beer, and see that there is a (new to me) feature in the water adjustment page: Sodium metabisulfite addition is calculated for dissolved oxygen reduction in the mash. The water adjustment page recommends doses from 10 ppm to 60 ppm based on how open or close the system is to oxygen. My system is definitely on the upper end of this scale.
I brew with tap water so typically I use Campden tablets (KMS) to eliminate chlorine, etc from my brew water. (And I probably overdoes it by splitting a tablet between mash and sparge water for a 5 gallon batch.)
So my questions are: if 50-60 ppm SMS is added to tap water when I would normally add Campden tab, will it serve both purposes? Will it eliminate chlorine and absorb oxygen? Do KMS tablets have the same oxygen absorption capacity as the suggested SMS addition? In other words has the Campden tablets been doing double duty all along?
I'm guessing that I should not use both Campden tablets for chlorine and SMS as an addition to absorb oxygen. I've tried to read what I can to understand these additions and their functions, but each appears in isolation as if occurring in different universes, rather than the same brew pot.
Any insight you can provide is appreciated.
Oh, and by the way, I found chemistry 101 a huge challenge in college, or is that already evident?
