Yep. When I had this issue I was feeding daily. I cut back to twice a week, I picked wednesday and saturday to match my work schedule. I did my water changes on monday so I could mix water on sunday. Monday as I started to siphon I would rip the hair algae out and throw it into my waste water bucket. Siphoning after you pull the algae out will mimimize spores and other crap that could possibly be released. Don't pull it all at once, it'll just cause a parameter spike since all that algae is consuming the nitrates/phosphates in the tank currently. Could stress/kill fish/coral, so do so slowly.
