ID pls... hair algae, cyano, diatoms... ?

[testertips]

Hi all,

Tank is approximately 2.5 months old and have some hair algae type growing on the rocks - it's more brown than any other color. Don't think it's cyano since it's difficult to remove but unsure - stuck to surface, doesn't blow off. What do y'all think it is?

Is it strands like hair algae?

Yes, and appears to be getting longer

Basic slime algae. You should check your snail poulation.
I mentioned it in the other thread with the same algae you posted.
