Looks like lyngbya to me. Does it blow off easily with no root left behind?

Here is a recent thread of someone who is actually getting it to slowly go away.

How to get rid of Lyngbya

I've been battling an unknown algae in my 4 month old 40g reef for 2 months now, and nothing I do seems to make any difference. I have identified it to be lyngbya at this point, it grows in a brownish hair like structure very quickly, almost exclusively in high flow areas. I was doing 20-30%...

I don't think it's either. I had a strain that looked eerily similar and it was definitely bryopsis mixed with gha. Tried everything cause I thought it was turf. Vibrant/algaefix did nothing, lowering nutrients did nothing, 3 day blackout did nothing.

Treated fluconazole and 90% was gone is a few days. Rest of it gone in a couple weeks. It became pretty clear after the vibrant and a bunch of manual removal that the fern like shapes were just hidden in the long strands because there was more than one strain.

@ryshark semi easily but a toothbrush fully removes it and the root

Could always throw a literal army of blue leg hermits at it. Like 1 per gallon kind of army.

I find lyngya kinda dissolves if I rub it with my fingers
