I have used several different types of reef glue and some work better than others. Trouble is I don't remember what is best. I got something from a company in Boston I believe that worked well. I have a few frags that I would like to glue in so wanted to see if anyone had any recommendations. I have never used superglue cause I am never sure which one to get. I would like to put the frags on rocks and some on the black glass. Anyone have any recommendations?
