I have a mc122 PH controller for my calcium reactor and have been having issues with the ph going to 0 or 1. I've swapped in several different ph probes I have on various tanks and they then seem to all go "bad" after a few weeks. I also notice that when i touch the controller body the ph drops or jumps...which I assume is due to some stray voltage somewhere. Any thoughts?
My current thought is to just replace all my probes as they are all 1-3 yrs old even though I calibrate them every so often. But, I don't want to waste too much money on probes if it turns out the controller is toast.
