Turbokeu's has a very particular fishtank: most of its functions are electronically controlled. Some controllers were made by himself, such as his temperature monitor, and some were bought such as his pH controller. Among the "features" of his tank, and beside the two already listed, there is a timer which controls the light intensity according to time, a CO2 monitor, some pretty plants and, of course, nice fishes.

Several photos are available on his page dedicated to his fishtank, but you could also take a look at his other projects (mostly electronic) on his website ! He made very nice nixie clocks, and a totally outstanding watercooled PC case (yea, i'm a fan...).
