Are the "hairs" really short, about 1/4", but really thick like fur? That stuff is hard to remove!! You literally have to scrape it off bit by bit from the surface it's growing on.
I had a problem with extremely long hair-like algae but it was bright green. Actually, it wasn't really a problem ... in fact I let it keep growing just to see how thick the growth would get. It was like a huge ball of green cotton candy! The fish loved playing in it. I finally cut it back with scissors before it took over the whole tank. I've never had that type grow again ...
