First and foremost i understand how you came to your name Frankenstein, and love the aquarium cockpit. I myself am constructing an Arduino aquarium controller, it's not entirely for the weak of heart since it does require some programing know how(or copy and paste from the internet into the IDE), and some understanding of electronics(again something that can be copied, but soldered from the internet). The beauty behind using the Arduino which is a programmable micro controller, is that it's limits are based not solely on it, but your imagination, Temperature, Salinity, PH monitoring. For controlling the sky is the limits, pump operation, turn your power heads into wave generators complete with oscillating(if you have multiple power heads), light control(on, off, dimming/fading(led or incandescent only)), auto feeding. And then it can be monitored by several different methods, LCD display, Touch LCD Display, directly on your computer if connected to the controller, VIA Ethernet or wireless. it takes a little know how but there is tons of information available on the web for help with most of these things which are fairly simple aside from the network items but it's out there, obviously it's not an en devour for everybody BUT with a basic Arduino Uno only costing around 30$ USD vs. some of the controllers i've seen around it's worth at least just playing around with.
