HA HA, you got me Tecwzrd. I have been using Halides in conjunction with my T-5 system for some time since I keep clams and some SPS
corals. The sad part is the tank looked really sweet when just the halide lamp was on but once the T-5's kicked on it drowned out the shimmer of the halides.
I have talked to some people and they all agree that as long as I am not planning on keeping large, high light demanding Acro colonies then having the 150 watt halides on one side and the 70 watt halides on the other should work fine.
This isnt for my 180, its going on a 72 bow front I converted to a reef.
