I've also went out and bought the Reef Angel aquarium controller. This is an open source arduino project and you program the thing in C++ so the possibilites of what you can do are endless. Right now it's managing my lighting schedule (no more timer dials!!) and giving me some control via my iPhone to turn things on and off which is huge. It will also manage feeding mode and water changing mode so I don't have to go pulling plugs out. Here's a shot of all the equipment mounted on the stand door. It really came out pretty nice if I do say so myself.
