ph Probe misreading after power outage

[Stevorino]

Hey All -

Been using my Apex System for a couple years now without an issue - I love it!

Power went out unexpectedly on Friday and since then my ph has been reading ~12.5... which is definitely not the case - everything seems to be functioning totally normal. Power only went out about an hour or so.

Things I have tried:

- Cutting Power and restarting (multiple times)
- Softly cleaning the probe with a new, soft-bristle tooth brush
- Soaking the probe in Vinegar a couple hours ... and brushing again....

It's still reading somewhere between 11.8 and 12.5. Any ideas on how to fix it?

Calibrate it.
