With such light at the top of the tank (48" tank, something like 90-125g, right?) you can have a lot of LPS and softies.
I have 110W PC on a similar 48" long tank, 90g, and had white pom-pom xenia, anthelia, neon-green candycane, hammers, frogspawns, purple frilly gorgonian, purple lemnalia (or looking alike), white lemnalia, bright red mushrooms, yellow polyps.
Giant green hairy mushrooms in the middle, clownfish hosted it.
At the bottom (24" depth) were Kenya tree and gsp. Only the growth was slow.
All are good beginner's corals.
