Hey hoping someone can give me some tips or pointers on how to get my pH module for my calcium reactor back online. I think it’s called a PMM module or something. I thought it was the probe but I swapped out probes and the probe was working just fine. About a week ago the pH for my calcium reactor became slow and it got worse the more the week went on. So today I unplugged the module and plugged it back in. Now the module says disconnected and It will not reconnect. Do these PMM modules fail often? Any help as I am not a pro by any means.
