not exactly on topic, but if you're looking for automation. Check out neptune systems or reefkeeper aquarium controllers. The could basically run your whole setup, from dosing nutrients based on readings from scientific grade probes, to controlling vent fans, timers, humidity sensors, co2, flood sensors. The ability to time outlets is amazing, they have their own programming language which is rather easy to learn, allowing you to basically program the units to do whatever you want. Some of the more interesting out of the box features are the ability to mimic sun and moon cycles exactly, hehe.
