Help ID some weird stuff in my fuge please

The only hesitation i have about taking it out is that if it being caused by a nutrient problem and i remove it the nutrients wont be used used up and this stuff may end up in my DT. If it's something beneficial I don't want to throw it away. I like my fuge to be filthy, the more stuff using nutrients down there the better.

I check the picture on Reefcleaners. It's not dino. It looks like really long strands of hair.no bubbles. i got some pictures of it. It start from the piece of coral rubble and grows to the surface. It isn't on the glass or rocks just in the water column.

Root?
