I dont see why you couldnt do it either way.You can bring tubing down and change over to pvc.Or you could do it all with tubing.You can get all sorts of fittings that have "barbs" on them for attaching to tubing including valves.I would keep the flow thru the fuge low to keep the pods from washing away and most will agree that cheato grows a bit better in slow flow.
