I would also put a background on the tank. Sunlight is great for corals in the wild but not in a closed system like our tanks.
If you aren't worried about getting corals any time soon stick with the lighting you have.
When you are ready to go reef then you will need to look at getting better lighting. I personally prefer MH
over other types of lighting but it all depends on what you want to keep. I have an SPS
dominated reef and they require high lighting. If you are wanting to do a few SPS
then you could easily have a nice reef with T5s.
I have a combination of MH
and T5 on my tank, but as I said I have a lot of SPS
