You guys went from a sump to a canister? That's like switching from Bluray to VHS. And because of the noise? That makes me laugh. If you did any research, you'd see that with a little planning and work, you could make a sump/overflow setup that's completely silent. Ever heard of a Herbie, or Beananimal overflow setup? You can run thousands of gallons of water per hour without so much as hearing a trickle. Don't believe me? Watch my videos:
Herbie (sound is amplified on this one a lot, you can even hear my breathing)
