Were on the same page. The older I get the less I seem to see, on re-reading the thread I noticed that the OP didn't want to add any more in tank flow, so sorry if I seemed to contradict you. His total display flow is way too low for anything that needs, if anything does, that much light. Seems like 3-250w halides would take care of bussiness, IMO 4-400w halides is bit of overkill for a 5ft tank.
