Turbo snails would do the trick, you could also try not having the lights on as much.

i had some hair algae on my brown zoos in a 10 gal, and a little on my LR. I bought 4 emerald crabs and they took it out in about 3 days. The zoo doesn't even look the same, it looks much better. But watch them around your corals. It's hard to tell if the larger ones are cleaning or eating my corals. But considering what the rocks look like now and that everything is intact, I can say they did an excellent job.
