Houser,
Just do what trent says and you'll be ok for this batch. It sounds like the main issue is the 15oz of acid malt that got into your grist. Did brewers friend tell you to do that? If so probably a bad calculation. I would recommend you take a look at ezwater, and when you get comfortable with that after a few batches, go have a look at bru'n water. Both will likely be superior to brewers friend for water calcs.
In the future, i would recommend having your lhbs provide the acid malt separate from the rest of your grist so that you can measure and add only what the water spreadsheet indicates. Not much can be done after its mixed into your grist.
Happy brewing!
