Hmm if it were me I'd run a hang on back filter like an aquaclear 70 ro
even a 110, or make a fuge out of a 110 AC
I would do my water changes and wait and see if I needed a skimmer. On a tank that size youre kinda in between needing one and not quite in my opinion and experience.
As far as lighting, I would look at a fishneedit.com fixture. pretty cheap and it would allow you to keep most corals. Nem is on the iffy side with that light I would think though. Lemme see if I can find a picture of my torch coral
