While changing out my cracked sump today I took my pH rpobe and ORP probe out of the water and did not think to put them in some salt water. They were probably out of the water for 2 hours or so. Did I ruin these probes or are they going to come back around. I measured the tank with my handheld pH meter and got a 8.2 but the intank probe showed 7.59 so I calibrated the probe and wound up with the same thing. The probe has been in the tank now for about 3 hours and it has drifted back up to 7.97 . I sure dont want to replace a probe right now. A penny for your thoughts.

ORP is fine. It can be stored dry.

If you can calibrate the pH probe to read the calibration solutions OK, it is good to go. :)
