Remove GSP

[jimmypencil]

Based on these pictures, how would you guys go about removing this gsp? Several months ago I removed this rock and spent a lot of time scraping all of the gsp off that I could. I truly didn’t see a speck when I put it back in the tank but here we are. Removing the rock really isn’t an option anymore because I don’t want to damage the sps in that area.
