Last week we got our halide too. The light previously on the 42 hex was a puny 20 watts or something as poor as that, though the tank is surrounded by three big windows which made up for the poor lighting.

All we did was remove the old light and put on the halide. Have noticed an increase in algae on the glass, but have had no problems with corals suffering from the extra light so quickly. Actually think they're growing now
