What is this growing on my rock

[BLUEaquarium06]

Not the hair algae, I've been battling that for awhile now and I'm just starting to get it under control. But this stuff is growing on the rocks of 2 corals I got from the same store some zoas and a mushroom I have no idea what it is

It all looks like algae to me.

kind of looks like Calothrix algae but hard to tell , blue/green with kind of a slight slimy hairy/fuzzy look almost looks identical to dino's , it may have bubbles present through out the algae ,
you may want to look on this diagram see if it looks similar .

That guide was very useful, thank you. It is absolutely no doubt Dictyota. It's cooking out those mushrooms and zoas pretty bad. I tried to manually remove it earlier today so hopefully that helps

that was going to be my second guess , a urchin will make short work of it
probably faster than some hermits,

I actually have a urchin in there haha his name is Steve, but he's been distracted by the hair algae issue I've been having. But I'm hoping that's just about fixed by now
