Carbon, phosban and religious large weekly water changes. Get rid of the pellets, cut down on feeding and shorten your light cycle. Pick out what you can, get some mexican turbos, a sea hare or a lot of trochus snails (or a combination of all three). I fought this battle in my 30g and I finally won. No algae in sight.
Are you sure it isn't bryopsis rather than hair algae? If it is, you are in for a fight.
Also, if you can tolerate the thievery, tuxedo urchins play the devil with hair algae. Mine doesn't allow even one speck to get started in my 72. However, be prepared, because they will steal anything that is not nailed down. If they can pick it up, they wear it as a hat.
