It's on the lower end as far as wpg, but with t-5's and a fairly shallow tank you would be fine with the lower light corals
Zoas, softies, some lps, all would look great in the tank.
I hear ya on trying to find a place for your tank in your apartment. I have the same trouble in my place, can't wait to buy a house
Just do your best at limiting the light from the window. What are you using for filtration
