I posted this over in the algae thread but haven't gotten any response so I figured I would see if the RSM crew had any ideas. I have this purple fuzzy algae growing all over some of my live rock. From what I have read it sounds like turf algae but its not red. Any ideas what it may be and how to get rid of it. I tried scraping it but the stuff doesn't come off.
Here are some pictures:
