I would just wait it out then. It will disintegrate in time. Fighting algae and dealing with the conditions that cause it takes alot of time. Unfortunately, this hobby takes alot of patience.
+1. This is probably your best option at the moment. While I did say that AlgaeFix did kill the hair algae, like any algicide, I wouldn't use it unless you absolutely had to. Like I said, my tank was completely overrun with hair algae, so aside from removing all the plants and starting over with new plants, AlgaeFix was really my only practical option for timely solution. I wouldn't get in the habbit of relying on algicides, but it could help bail you out should a worst case scenario come up.
