What are you controlling with your Apex?

I control my fans based on temp.
I set my ATO on an alternating schedule from my Kalkwasser.
My kalk is tied to the Ph probe. My calc reactor is also tied to Ph.
I have a 1/4" John Guest solenoid that opens the ro/do for a couple of hours each day.
I put my power heads and return pumps on a feed cycle.

Basically every device in my system is on an outlet. It makes it really easy to shut things off for maintenance.
