Green Hair algae problem and how I'm dealing with it

I'm currently fighting a battle with green hair algae in my 72g reef. The main source of the problem was the tank was getting too much sunlight. I've since solved that problem by blacking out the back and side of the tank so that no sunlight can get in. This seemed to have helped some, but I still notice the hair algae growing fast! I've also been doing 30g water changes every week and have recruited the help of a dozen snails and a sea hare. They seem to help the problem some..

I also placed some macro algae in the main tank to help suck up some of the nitrates.. but other than that I've been trying to manually remove the hair algae by hand as much as I can. UGH! What a mess hair algae can be! I'll keep everyone posted on my battle with green hair algae in the reef. :/
