I had a what sounds like the same algae you have/ had. Thin long green hair like algae and the thing that worked with it was turning off my filter, do my water change, I took syringe and sprayed the H2O2 over the infected areas making sure not to go over the recomended amount, waited fifteen minutes, then refilled the tank, and turned on the pump. I had to do it two to three times and never saw it again since!
I'm workin on it James! Thanks for the tip! Guess I should have done that yesterday with my water change...
