ORP very low and PH dropping

Like @Randy Holmes-Farley said it is likely a testing error. I would open a up a support case with Neptune.

I'm not sure why you are looking for anything more than a testing problem. I do not believe the ORP is as low as you report, and most definitely the ORP did not spike up and down on its own without adding some unusual chemicals exactly when the spikes happened.

Thanks Randy

It did seem to be the testing/probe. After some more time it went back up.

Good to hear.

Happy reefing.
