Sorry I should have been more specific. IMO SPS corals will need Metal Halide lighting.
Adding more light to your tank will probably allow you to keep most softies and probably some LPS corals. You will have to keep in mind that it will also add heat so you will have to manage that with either fans or a chiller of some sort.
