What the ORP!? 921?

Checking my apex this morning and saw this spike from yesterday.

I don't use ozone. I dose Randy's 2 part and nothing else.

Just a random false reading for 15 minutes? What could cause that?

ORP is not something I really pay attention to, and nothing looked out of place in the tank, but 921 seems high and weird.

ORP probe is in the drain portion of my sump.

Something I should look into further or just write it off as a blip?

Perhaps a voltage spike??

Definitely not real.

Definitely not real.

That's what I suspected, thanks. I even re-read your ORP article to try to come up with an explanation.

Maybe a sign that the probe is failing? It's probably 15-18 months old...

I'm thinking it is time to get new probes if they are all the same age..
