My bottles run at room temperature.  (84F in the summer, 75F in the winter).  I 
don't see a tremendous decrease in useability even in the winter.

My tap water hardness is KH of 5.  This value will make a difference in how 
much baking soda you should add, if any.  If your KH is 15 for example, I 
wouldn't add any baking soda.
