Noisy Overflow

[medictwo]

Hello all I have been reading these boards for quite awhile as I am new to the salt water hobby. I ran fresh water tanks for years and decided to take on the challenge of the salt creatures. I setup a 92 gallon corner tank with a sump underneath and now I have a problem. My overflow is extremely noisey. I would like to fix it but if i overflow it due to restriction my wife would divorce me so I need your help. I can hear the thing from down the street, well not really but it seems that way.. This is probably one of many questions to come as I am just starting the cycle of the tank now, but PLEASE HELP ME. :help:

MINE IS THE SAME WAY TO TELL YOU THE TRUTH MY MOM IS YELLING AT ME AT THIS VERY SECOND ABOUT IT AND ITS REALLY PISSING MY OFF LOL WHAT I DO TO MAKE IT QUIET IS LOWER IT JUST A BIT AND ADD WATER TO YOUR MAIN TANK IF YOUR WATER LEVEL IS ALREADY ALL THE WAY UP JUST TRY LOWERING YOUR OVERFLOW BOX AND SEE IF THAT HELPS??? IF NOT IM NOT REALLY FOR SURE IM GETTING READY TO ADD MORE WATER TO MY MAIN TANK RIGHT NOW SO HOPE THIS HELPS

I hope my overflow isn't noisy when i get it.

Let me know if it helps, I would think it would just help until that water drained into the sump..

I had the same problem so what I did is; I extended the piece beneath the lower bulkhead to ensure it was under the water level. I also place a folded hand towel over the overflow box. It has really helped.

Google durso standpipe if you have a pre-drilled tank and stockman standpipe if you use an HOB over-flow. :happyfish

i did the same as hot883 and it worked wonders.

I made a durso standpipe and it works great to solve this problem. If the noise you get is a periodic flushing after installing a durso and the durso is operating correctly, then the problem is different (most likely the line from the overflow to the sump needs to be straightened).
You will often see people placing LR rubble or bio-balls in an overflow chamber to reduce the splashing.

Well I am going home in the A.M. and then grabbing a nap, once I wake up I will try some of the ideas. I went and searched google like one of the threads suggested and there was a lot of different ideas that I will NEED TO TRY. Thanks for all of the help..

if it is one that hangs off the back of the tank you can cut a peice of plastic and place it over the top of it. I had to do that on my 29 gal and its has almost stopped all the noise.

by saying that the sump is under the tank, the tank is pre-drilled, right? if so there is a pipe that the water flows into to go into the sump? if so, get one of those $5 foam pads that they sell at the lfs. wrap it around the pipe where the water enters the pipe, and tighten it with a tie strap. this will erase the noise. the only thing is, the pad will eventually get clogged with gunk, so you'll need to either remove it and clean thoroughly or replace the pad.

If it is a gurgling noise coming out of the overflow, you can put a ball valve on the line coming off of it and SLOWLY close it until the noise stops. The noise is air getting sucked into the line, by closing the valve you will stop the air from getting into it and your flow rate sometimes will actually go up as the volume of the pipe is now full of water, not air and water.

No, you can use a over-flow box to drain the water.

Not only will it clog up frequently, it will slow down your water flow. The same reduction in flow will happen if you place your drain line below the water line in your sump. :happyfish

That is a flood waiting to happen. ***)
