Brown hair algae and skimmer question

[SleepyPirate]

I have recently had a brown hair algae outbreak, my tanks been running for about 6-7 months now although it was seeded with my prior tank which was running for over a year. My protein skimmer has never actually collected anything and actually does not produce a foam or bubbling, at first i thought it was cause there was nothing to skim but now that i have this brown hair algae outbreak there has to be something in the water for it to skim does it not? iv never had to empty the tray or anything like that.
