you could try toothpicks. the round kind with the pointy ends, not the flat kind. if it doesn't work at least it won't scratch the glass. draw the toothpick right along inside the scratch. it should get a lot of it out.
lol I haven't tried yet. I'm going to try some of these... to be honest the algae is starting to go away. I finally added a Fuge to my tank with Chateo (not sure how to spell it) algae and its like all my other algae's are just going poof. Im astounded.
