Mary Jo, I haven't been following this thread but I noticed you are using pH Up! You should know three things about it:
1) It will raise you t/a as well as your pH
2) Because of that we generally recommend using Borax instead ( yes 20 Mule Team Borax!)
3) pH Up! is EXACTLY the same as Arm&Hammer Washing Soda (next to the Borax in the laundry aisle), being Sodium Carbonate or Soda Ash, only it costs 3x to 4x as much as Washing Soda.

FYI
