Christy,
Hang in there, the hair algae could be from many different sources. Make sure your alk is high enough and patience. Here is a pic of my tank during the hair algae stage at about 7-8 months. Look in the background behind the mandarin. I just raised my alk to proper levels, minimized feeding, kept the skimmer really clean and waited it out, I did not pull out much by hand.
