Algae Identification

[sumant19]

Need some help identifying this algae. It might be bryopsis because I foolishly tried to scrape it from a different rock and it spread to other parts of the aquarium. However, it is very flimsy.. i can blast it with a baster and it just breaks off. I read that bryopsis has a strong root structure. So dont know whats going on here.

Nitrates and Phosphates are undetectable. CA - 420 Alk - 10.2 and Mg 1400.

My yellow tang and snails are not touching it..

Not Bryopsis. Looks like GHA.

Not Bryopsis. Looks like GHA.

I hope that’s the case …. Lesser of two evils.. I will do a large water change.. recently my big emerald crab died.. may be that added extra nutrients in the water… the nitrates are undetected because may be the algae is consuming excess nutrients

Does anyone think it could be Lyngbya and not hair algae. I am trying to figure out the difference between these two since I read that they have some of the same characteristics.
