Is this good alage or bad growing in sump

Hi new here, need help identifying if this algae growing in my sump i was trying to do a refugium but starting over, after taking out the cheato algae I noticed this growing on the walls . Also have a fuzzy kind on the rocks .

Really, ANY algae that grows well in a refugium is "good" algae. The point of a fuge is to grow stuff there that will take up nutrients that would otherwise be used by algae in the display. Most will prefer chaeto, caulerpa, etc, but having gha or other algae in the fuge is no different than having an algae scrubber. Heck, at one point, my fuge was covered in cyano - but zero in the display
