Do you test for Si? I don't know how it would get in there but cyano lives on that it so that could be a part of your problem. Like I said my tank looked like crap but with water changes and hanging a bag of phos and Si remover that has taken care of the problem. Plus I have bumped up the flow and kept the temp a bit cooler then it was running in the summer when I set up the tank.
I don't have much hair algae by the way, a little but I hate the caulerpa algae and I have some fern like algae ... very light honestly not sure what the heck it is but invasive so I try to pluck it out.
