I've ditched my controller entirely. I have a profilux not an apex, so I'm not too familiar with them. But with the profilux, I can tie them together and run them through a random mode. It took a bit of messing around but looking back its simple enough.
I put 4-25's on my 300 in each corner, works very well. There is not a single dead spot in the tank. I did like the else mode, but having control over each one is real nice.
Sorry couldn't be more help, but for me, control over the powerhead and a random pattern through the profilux, made me ditch the controller.
