I took a PH reading today and the first picture is when I first shook it up. It looks like about 7.2. I got distracted and when I came back the color had turned much pinker and it looked to be 7.8-8.0. I was gone only a few seconds. Is this normal? I never noticed this before. I expected the PH to be low because I had just added 4 pounds of CYA.

Is your FC above 10? As far as I know, you can still test for pH when just a bit above 10 as long as you do the pH reading quickly, but then the FC will start to change the indicator after a few seconds. That could explain what you were observing.
