My suggestion, would be to keep your paramaters stable keep doing water chan he's at 25-30% weekly and run gfo but make sure the outlet trickles slowly, that way it has more reaction time. The hair algae will soon get exhausted, if it grows long that's even better.... Shut off flow and pull it out with your fingers. Patience is the key. I had annoying hair algae grow for 6 months, cooked most of the rock but 2 pieces which still have some, as of late I've noticed it starving out and patches of rock are starting to appear.
