What are you trying to show us? I see coralline algae.

Is it all the green algae?
Do you use R/O water?
Over feeding or too much light,, no UV?

If thats the I D, I'd remove it before you have many, many, many, many more mussels.
Very invasive!!!

I would leave it. The more the merrier. It will also assist in filtering the water.
