The tank is 6 ft long. It's a 72"x24"x30".
And I'm building the hood, so, I will have some flexibility in how I mount the MH
lights. Or I could leave the top off the hood and suspend the lights from the ceiling.
I thought that I needed the 400W MH
because of the depth of the tank. I don't want to have to worry about making sure everything stays on a shelf of rock or anything. But, I plan on having plenty of rock.
But, am I likely to have MAJOR heating problems with the 400W?
Oh, and I'm not sure about what corals. I'm planning on adding some reef-safe fish, green chromis, 2-3 Tangs, Building up my live rock collection and then upgrading the lights eventually and probably add an anemone and start looking at what corals might work.
