I used too much phosphoric acid in my mash. Can I counter the phosphoric acid with baking soda? Has anyone tried this? Did you get good results?

Any alkali will work. You might want to consider trying slaked lime (pickling lime, calcium hydroxide) as this may precipitate some of the excess phosphate. No, I haven't tried it but it is very fundamental acid/base chemistry: HAc + B(OH) --> BAc + H2O

Any idea what will happen to the Phosphorous? Will it settle out?

Edit: Oops, I guess you already answered this. Thanks!
