Pool math app?

I'm trying the app, I set the pH at 8.2 and to get to 7.5 it says to add 2.5 oz acid. I have never added that little amount so I checked the pool math website and it says add 27 oz. I have them both set to 12,000 gallons.

In the app, you enter your test results and save them by touching the check mark in the upper right.

Then you touch pH and determine what target level pH you wish. Then the app determines how much of what ever product you select to add.
