When I was having the beginnings of a hair algae issue, I started to use a phospate sponge to remove it's food source. That did stop it from growing, but did not address what had already started.

For the existing hair algae, I pulled the big parts and added a foxface and lots of astrea snails. The problem is basically gone, only a couple minor spots left to deal with.

If this tank is less then 1 year old, it is extremely common to go through these phases (cyano then green hair). Get things to eat it, phosphate remover, and hand harvest. A refugium can help out a lot as well. Be patient and it will eventually go away.
