Looking at you photos it appears that your screen is growing at least one species of ulva, which is a macro. It's exactly what you want growing.
I assume the algae appeared naturally on your screen (not seeded)?
Do you use NSW or synthetic salt when you do water changes? And, have you ever added any proper live rock (the rock that has a variety of live stuff all over it) to your tank?,,, or dry rock only?
