Drilling for a closed loop is all dependant on where you want your outputs and drain(s). Some people drill in specific locations that they have determined to hide all plumbing behind rockwork, while others drill the bottoms of their tanks for closed loops to keep detrius suspended in the water column. I guess what I'm saying is, drill em' where ya want em'.
