Try yanking off as much hair algae off the rocks as you can, do a 30to 40 % water change and keep the tank in total darkness for 3 or 4 days. The corals you have shouldn't be harmed and the fish don't care about darkness. How old are the bulbs on your m/h ?

I will give that a try. What about ambient light (from windows)?

How much ambient light you have? A lot of lights from windows will always promote algae.
