My system is silent (except some sound from my return pump...Quiet One?..yeah right!) but as it's an in-wall it's barely noticeable. Probably easier to show a pic to explain:
The overflow plumbing is all 1.5" PVC. From the overflow it goes to a "T". One leg goes straight down to a ball valve, the other leg goes across to the "fuge" side of my sump where it elbows to an exit
below the water line. The ball valve on the bubble trap side of the sump also exits below the water level. I think this is key in keeping it silent. I think I got lucky in that the return flow from the Quiet One 6000 seems to match up well with the overflow plumbing so not a lot of fiddling was required. By adjusting the ball valve on the overflow I control both the level in the overflow and also how much water goes to the fuge. The baffle for the fuge is sloped at about 50 degrees so that rather than tumbling over a cliff the water "slides" down to the center return section and creates no noticeable bubbles.
This was a standard tank and as Slick Fork suggested, if a custom tank I would have gone with an external overflow so it takes no in-tank real estate plus it would look a lot cleaner. I will be going all external on my planned "monster tank" that I will hopefully start this summer.
