i think your going to need more light then that.
i have a 20 gallon tank and i have a 65watt pc
light, about to have to get another 65 watt pc
for the same tank. 130 watts total, you have a larger tank and less light then i w/ a smaller tank an i may not be able to have stony corals yet. i think youll need about 8 or so watts per gallon for stony. which you are way under.
in your case, you should be able to keep polyps and a leather, just soft corals.
there are some great corals that dont really require light though, they simply need to be fed through out the week, you may want to look into it if you dont mind spending time w/ your coral and feeding it w/out running up the light bill.
