Distance between light and surface water?

Wondering how far my two 175w 14k pheonix lights (in huge lumen bright reflectors) should be from my 150g rubbermaid tub/frag tank.

try higher then you can always move lower. i would think 12-18 inches above the water is going to be good depending on what corals you plan on propagating. 12 inches is probably ideal.
