what is this

[Kolby’s Reef]

can someone please explain if this is bubble algae or what kind of algae it is and how to get rid of it. It’s in my tank and chaeto.

Not bubble algae. To me the picture in display tank looks like bubbles stuck in cyano. And just a lot of bubbles in what I assume is cheato.
Did your skimmer go mad and dump a bunch of bubbles into the system? Or a pump suck in air somehow? Or a baffle in your sump not trapping bubbles for some reason.

Just my thoughts could be way off though.

I recall when I had a fresh water tanks plants occasionally produced bubbles do to photosynthesis, not sure of large amounts of cheato can do the same.
