Can someone identify ?

I’m trying to deal with the bubble algae- but the red seems to be getting worse and spreading. Dinos? Feedback appreciated

Looks like cyano bacteria. Siphon it out regularly and use a baster to blow the remainder off into the water column so your mechanical filteration can catch it. Rinse mechanical filteration once water column clears up.
