I want to build a 48"x24"x12" propagation tank out of 3/8" thick clear cell-cast acrylic. I want to use single ended metal halides to light the tank. I'm thinking about hanging the lights 8-10" about the waters surface. The actual water height will be around 10.5 to 11 inches. I’m thinking of using two or three 20K Radium 250 watt single ended metal halides but maybe 150’s will do the trick? I will house all types of corals: SPS, LPS, Zoo’s, Mushrooms and Softies. How many metal halides should I use, two?
