I have a 20 long with sps and soft corals in it. I just bought a 150 watt MH fixture and was wondering if that would be too much intensity for my corals. How high off the water should I hang the fixture, what spectrum bulb would give me a balance of growth and still easy to look at? I dont have any actinics. Should I go with a 20 k bulb since it is such a shallow tank?
