So I have this green algae that grows in ball form that have a thick matted structure. This is not hair algae. Turbo snails don't touch it, I have a sea hare in the tank and he doesn't touch it. I can pull off some of the algae but can never full get it off the rocks hence why the picture looks so bad.

I understand nutrient control is always said but am looking for some help from something in addition to help get rid of this algae after I pull as much as I can out.

Maybe an urchin or foxface lo?
