I thought it was gluing it to the magnet itself on the earlier models when the skimmer first came out. I was going to do this but when i took it apart it was already attached to the magnet. So i thought Rio had made this mod themselves for newer skimmers. Let me know what u find.
Ok just found it... looks like its to the magnet itself and this is already done by Rio.
