Hair Algea or Something else?

[Montezuma]

So im in the 5 or 6th week of cycling. My reading are good, but I have something like hair algea growing. Its really long hairs, and not bunched up. Almost looks like real grass. I;ve had hair algea in other tanks, but this look different. Any ideas?? I will post a pic later.
