What kind of algae.

[Isiah1820]

I have a few pictures attached and wanted to get a Id on the type of algae I have. One is on the power head and back wall mostly. And the other is on the rock and killing the coraline I had growing. It’s a dark brown color. I also have a full tank shot. Taking thoughts and opinions lol

I see some bubble algae in some of the images.

I don’t have bubble algae. What you maybe seeing is just bubbles like the ones on the back wall picture.
