Algae ID

[mrhasan]

So my tank was pretty clean with nitrates around 5ppm with corals thriving and being colourful and all. Decided to try aquaforest amino acid and vitamins and 1 drop of amino and BAM algae all over the rocks. I have stopped using it (along with the vitamin) and seems like it is not helping too much since the algae is already there. For the life of me, I cannot figure out whether it is some form of hair algae or dino. It is brown and it is hairy, stringy and forms bubbles only after water change but it is not as long as all the pics I am seeing online for dinos. And it does not appear to be "colonial" and using turkey baster doesn't seem to blow it off the rock. Here's some pics:













Any idea what is going on here? Thanks in advance
