Hello all: I want to control my Ca Reactor using the pH probe via a Neptune pm1. I installed everything, and the pm1 is showing-up on my Apex display screen. I am not sure what to do now? Can someone direct me to, or perhaps give me a step-by-step to get this going? Right now, the pH probe is showing that the pH that is being used for the Ca Reactor is 2.0. This is not correct, as I know that my pH is much higher. The reactor has been running both pumps for 24 hours w/o the Co2. I am purging the air, and don't want to dial-in the C02 until everything is set-up properly. I have enabled the pH probe in the pm1, but again, it's not showing the correct reading, so something is wrong. Any help is greatly appreciated.
