I’m aware that FC over 10 makes the PH test unreliable.
Today, I found that with FC =9.0, the PH reading came out at 7.4 immediately after inverting the large tube. But after letting it sit in the vial for about 2 minutes, the color changed to read PH 8.0.
My gut tells me to trust the initial reading since the FC is close to the upper limit, but was hoping for some validation or correction to be sure.
