How are your phosphates? Are u using RO
Pick up a book on corals. I like Eric Borneman's "Aquarium Corals". I'd suggest some picture and write-up cruising before setting your sights.
In the meantime, start with some easy ones... mushrooms, ricrodia, leathers, frogspawn. I'd also suggest wavemakers for your powerheads. Alternating flows seem to help corals quite a bit IMO
Sounds like you've covered with enuf light for any kinda coral you want. Hard or soft. But do some reading of level of difficulty and placement, feeding, or etc before you leap.
Good luck and welcome to AA!!
Gonna hang around for a while as you decide and stock your coral?
