Question for apex users do you measure orp or convert that port to a second ph probe spot? I like having the second ph probe for the calcium reactor but just curious who monitors orp
orp is a waste of time... "tells you if something is wrong" i have a lot of visual indicators in my livestock if something is out of whack. i dont need a nonsense prob for that.
With the new apex can you switch that port to measure ph or do you have to buy another module to do it? Do you have to do it on the computer or can you do it on the phone app
