Help choosing lighting for 55g corner tank

[eternitybc]

Thanks Anthony,

I will look at getting actinic bulbs for now as it currently has 6400K ones plus I think they are quite old. Down the road if I do go the MH route would two 150w DE (300 total) be too much for my tank? If I only do a single I'm worried I might melt the plastic cross brace in the middle?
