Help not sure what this is

Not the best photos but I've been fighting what I think is dinos for a few months in my nano. Its a dust like algae on my glass but much more thick on the sand and some corals. I started a new tank and I'm trying to move everything over but don't want to chance bringing some bad algae in so I'm looking for a hand on what to do?

Does it have air bubbles in it?
That’s usually a dead giveaway that they’re Dino’s...

To me, it looks more like diatoms... But I’m not certain since it’s over your toadstool.
Usually Dino’s are the ones that smother corals like that.
Better pics in less blue light?

Changed lights now I see what also looks like cyano lol. I have seen very few less than 5 micro bubbles in some of it.
