While I do happen to use my controller to monitor tank pH, I realize that this is largely unimportant. The key here is that the controller is just monitoring...not doing anything with the tank pH. It also monitors ORP, which is also meaninglessly interesting.

What I DO use the controller for is heater and pH control of my CA reactor. If not for the controller, I would be purchasing a temp controller and pH controller anyway because I can't imagine running a tank/Ca reactor without those two things. Heater thermostats are too unreliable.

Then...since the controller is there...I also use it to control dosing pumps on the CA reactor and Kalk reactors. It also controls the lighting cycle of the refugium.

Oh yes, It also text msgs me when any parameter goes beyond limits or a power failure happens. I can also make adjustments over the web to anything the controller has control over.

I couldn't run the tank without one. I learned that briefly when mine broke. Lesson learned, I now have a backup unit in case my unit fails again.
