Adjust TA first, right?

You should end up putting about 8lbs of baking soda in (if your pool size and TA readings are correct)

Hope that helps.

That may very well be true, but I have found with baking soda, it doesn't always take as much as the bleach calc suggests, so I tend to add slowly rather than overshoot the target. Especially since she is already close to the desired range already.
