Good point Gary! Also, how you do your plumbing will make a difference too! Don't let the PVC rest against anything, or the vibration noise will get amplified. You way even want to consider using 3/4" ID vinyl tubing instead of PVC?

Point the back of the pump (fan end) toward a wall, and tack a 12"x12" piece of carpeting (or similar) on the wall to dampen the noise, but keep the pump/fan 3-6" away from the wall/carpet

Besides, who can sleep with Wendy creeping around watching her fish eat (Sorry, I can't resist whenever I get a chance to remind her about that post) :P
