I have a Eclipse 3 tank and flitration sitting around that I would like to turn into a nano reef. It currently has a 9in, 6 watt bulb in it which would give it a 2 watt to 1 Gal ratio. Should this ratio and blub be suitable for some corals? Also, where is the best place to buy 50/50 9in bulbs? i cant seem to find them anywhere.
