Hey folks, just a helpful hint; best method I have found for attaching these is to take your piece and use a pair of wire strippers to take about a 1/4" off the very bottom, leaving the black inner core. Drill a hole into the piece of rock to which you wish to attach it (I usually use a pocket knife) fill the hole with superglue, and then place the core into the hole. Place the rock into saltwater removed from tank till it hardens, then place where desired in your tank. Much nicer looking and easier than try to rubberband it. HTH

BTW; Nice job Chuck
