lighting for a 150

[bjledbetter]

Will a 400w metal halide be enough light to keep haddoni mags/ acros going in a 4 ft 150?

If its just one light... I would say no. 400w MH is serious business in a good reflector.

It would be able to keep them in one spot in the tank, yea. It won't cover the whole tank though.
