That would allow you to keep anything yes. That would be plenty. I agree that a 4 bulb T5HO would be good for your setup as well.
The Marineland lights are not meant for corals, they say "reef capable" or whatever, but they are not anything more than supplemental lighting. There is no intensity, very few bulbs, and cheap low powered LED bulbs in the fixture. Really the fixture shouldn't even be on the market because for the price you can get better supplemental lighting or cheaper lights for a FO or FOWLR.
I went with the 4 bulb T5HO fixture. What types of corals do you think I could grow with it? I have softies already (zoanthids, pulsing xenia, and button polyps). Do you think I should just stick with softies?
