Help identify please

[smc03]

Can anyone please help my identify this stuff? My tank is realitivly new (just under 3 months). It cycled in a little over one month but my nitrates are still high (15-20ppm) which I’m trying to get down hoping it will help.

This stuff is brownish in color, very long strings that flow with the current of the powerheads if I touch it, it seems to break apart easily

Thoughts?

Here’s another pic that shows it a little better.

Welcome to R2R. I'll bump this for some algae ID experts.

Welcome to R2R! Looks like new tank green/brown hair algae GHA. Easy to remove with a toothbrush and siphon hose. Or if easily done, just pull the rock out of the tank, scrub with toothbrush, rinse off and return to the tank.

If the long strands beak off like snot , it’s a dino or snotty diatom
