Yes, Watermom - I can't type. 11,000 gal (although, I want to recalculate... today is pool maint. day).
I went to poolcalculator.com and figured out that I'm going to add 4lb baking soda, since my TA can be raised a bit, then I'll add some Borax. Test again. repeat.
I also need to add serious calcium per the calculator. I bought some, which I will add, then once again test. Repeat as necessarry (or however it's spelled).

I'm so happy that I found this site, from the bottom of my wallet and the top of my brain.
