Well I have ben vacing the tank really well for the last couple weeks and removing as much as I can. It seems to be helping but has not gone away. The stuff in the pelia is almost gone and doesn't seem to be growing. The thread algea takes a few days before it starts growing after removal and vacing. So I think I will try vacing removal and 3 day blackout in the next week or so as I'm starting to get sick of spending 30 mins a week reming the stuff.
