The guys at golds aquarium in calgary have a good silent overflow set up. If you call and speak with them they would probabally email u some pics. Having the return ran above the water level and then into the tank is the safest way to pipe it. On mine I ran the return over the overflow. Then I drilled a hole in the 90 on the return and tapped a small plastic threaded barb adapter in to it. I used some small diameter tubing to keep the water from the barb adapter in the overflow. I secured the tubing just above the water level as a siphon break. works like a charm. No more relying on check valves.
