Reefer_rob, 
 
I bake the baking soda for about 1 hr at 350F.  I do this in mass quantities and then store it in zip lock bags.  I bake it to drive off carbon dioxide which otherwise will lower your pH, not because it will dissolve easier in water.   
 
Baking soda is such a hassle and I to have problems with over saturation...not the easiest stuff to dissolve ugh!
