Well, I've made a mixture of water, vitamin powder, and plankton. When I go to work on Monday I'll feed my corals and my fiancee's some of it.
My work tank is a 13g cylinder, with the dimensions of 20" by 16". It is lit by an 80 watt 16 LUXEON LED array which I built myself. Corals include a couple mushrooms, finger leathers, micro-zoo's, and an anemone.
My fiancee's work tank is 40 gallons and has similar corals.
