Bad Hair Algae

[likwid]

Hey guys,

I have a 10g tank with 72w 50/50, AC500 refugium with chaeto and halimeda macro algaes and live rock rubble, and a, AquaC Nano Remora skimmer. The tank has around 15 lbs of live rock, an inch of live sand, and various corals. Also in the tank is a BTA and percula. It has been running for around a year now and I have been battling hair algae the entire time. I try to syphon out as much as I can during weekly water changes, but it grows back everywhere, including the sand and glass. I am now only feeding twice a week.

Any ideas?
