The stock light is long gone, that thing wouldn't keep zoa's alive. This bad boy has a custom led hood I made for it last year. We've alread kept Hydnophora successfully in it before (the green coral in the 2nd pic of the thread), it was way to aggressive for that small of a tank though. Birdsnest would good alternitive, so would Stylophora or maybe some branching Montipora. I would love to try some Acro but I'm not sure the water quality would be up to par.
You could run GFO to help, or something like Seachem's Purigen. With that lighting you should be able to do acro's. I had a frag in mine last year that was thriving and the only filtration I had was water changes
