ID algae/bacteria Please!

[Bender]

Hey all!

This popped up about a week ago out of thin air. It's almost like cyano but thin and blows off the rock super easy with a Turkey baster. It grows over all my corals almost twice a day I have to blow them off.

Tank is about 6 months old. Thank you!

Looks like cyano or dinos. A cheap microscope will you ID it.

+1 for Cyano or Dinos.

What do you nutrients look like?

I'll get readings on nutrients in a bit. They were bottomed out for a while and I've been slowly trying to increase them.

Another piece of info - it goes away almost completely overnight then gets stronger during the day.

This morning (sorry for bad pics)
