Hya - nope I go completely against the grain with all my marines no sumps, no all singing all dancing everythings just plain old tanks, normal marine lights, external filters (no I don't have nitrate problems) and loads of TLC (oh yeah and probably more frequent water changes than most people, do 20% weekly). It probably limits some of the corals I can have but I have a lot of tanks all set up under budgets. I have a feeling I get away with it because of the amount of macro algae in there - if I'm on a night time stalking session there are always loads of pods in it.
