Hey Josh, best to look it up and make sure. It some place in RC chemistry thread, I think it was some thing like this. Bake it on a cookie sheet at 350 for at least a 30 min. For every Tbs it will raise the Alk 1 point of 50 gal. If you use unbaked baking soda it will also raise the PH.
I am not sure why this isn't used in a reactor just like Kalk. If we keep talking about it and show how dumb we are then someone smart will chime in.
