so.. my overflow is 25 inches to the bottom... it sounds like niagra falls in there!!!!! How do I quieten it down? should I raise my overflow box water level and run less water in the sump? what do you guys do?
You need to use a durso or stockman stand pipe. Excellent pic of a durso in my tank build thread on pg. 2..Maybe a little short by some peoplesstandards but works great. Dont forget to drill a small hole in the top to prevent a siphon.
Funny, I just asked you what kind of standpipe you're going with in your picture thread!
I personally have Durso's standpipe (http://www.dursostandpipes.com) which works awesome (had to make the whole a bit bigger after the first two weeks, and it's super quiet now!) and was really easy to put together.
One thing I did add was a piece of PVC after the 90 degree elbow with various slits on it and a cap at the end just in case fish/inverts were to get in the overflow.
Either way, there are other options out there too. But like I said, Durso's creation does wonders for my tank!
1. High, less drop, less noise
2. The intake submerge is the whole idea of the Durso, submerged intake less noise (there's a small hole that to allow air, must tune it though).
3. Bigger better.
Look at the in the link someone else posted. Title picture shows it all.

1: A couple inches from the top is ideal. The higher, the less cascading sound.
2:Yes, It will only work submerged. The durso is made up of straight pipe, one "T", one elbow, and one end cap. You will need to drill a small hole in the top end cap to prevent a major siphon effect. Air does travel down the pipe with the water and can create a gurgling sound. Alot of people use a valve on the return pipe to control the amount going throught the overflow. This will help you control the amount of noise they produce. I actually glued an extra piece of tube to the top of my end cap and put filter floss in it to dampen the noise even further. Kind of like a large venturi damper.
3. Definately 1.5"
ill pick up the stuff today and post pics tonight or tomorrow. I'm glad i'm doing a "wet run" in the garage to get all this strait before moving it into the "inner sanctum".
Oh, one more thing. You do have the hole on top of the cap, right? And also, if your return line is underwater (I don't think yours is, at least not yet) a hole for the return line as well?
Make sure you've got those (mine are above the water level so I have nothing drain down to the sump) or else the siphon is never broken when the pump's off (i.e. power outage) and a lot could drain into the sump and overflow! 8O
I don't understand... - Why are all you people talking about quieting down this guys overflow when his real issue is that his overflow is poking around in his life unwanted?
Duh...
The thread title says its a NOSEY overflow.... :roll:
