I just recieved my apex and have began setting it up and am begining to think I'm in way over my head. I set up the temp and first ph probe and calibrated it easily. I then plugged in my second pH probe ( for my ca reactor) to the PH/ORP port on the aquacontroller. I cant find where or how to calibrate this second probe. when I go to set up all i see is my first probe named PH_sum. How do I configure this second pH probe?
