Redox Values Fluctuating Every Hour

[Terry165]

I have notice that my Redox values fluctuate on an hourly basis over the last couple of weeks. I have tried calibrating the probe but did not solve the problem. Any suggestions will be much appreciated.

Where is the probe located?> If this is just starting after sometime.. time for a new probe

ATO dumping water close to the probe?

Not sure if you found a solution but I ran into a similar situation with our GHL probe after I installed another powerbar and some more devices. The power cables were butted up against the probe cables so I re-routed them and recalibrated all of the probes and it has been nice and stable ever since.
