I brewed essentially that recipe with water adjusted to:

Ca: 47
Mg: 1
Alkalinity as CaCO3: 22

I read the mash pH and it was 5.15 at mash temp. So that is about 5.45 at room temp. That would have been fine, but I added 2 grams of baking soda and go to 5.24 at mash temp or about 5.54 at room temp. Anyway, what I am saying is that since you have more buffering capacity in your water, you probably don't need any baking soda at all.

I agree with beerrific on potentially not needing the baking soda. I'd leave it out and check the pH even with a cheap strip. If it's over 5, I'd call it fine.
