loud overflow

[jlscrug]

Hi,

I have just set up a new 20 gal nano. My issue is that the durso is LOUD. The little plug in the top was drilled with a 1/8" hole...which evidently wasn't enough because it would be whisper quiet followed by a rush of water that sounded like flushing a toilet followed by another brief period of whisper quiet then etc, etc, etc. I alleviated the quiet-flushing cycle by drilling another, larger 'breather' hole in the top of the plug on the top of the stand pipe but now it is too dang loud.

I down graded the return from a Mag7 to a Mag5 and this helped...a little...mostly with the water noise/splash as it enters the sump. My previous set up was very quiet but had a HOB overflow box which drained to the sump via on of those highly flexible, ribbed hoses like you see on a pool pump. I think the trick there was that it was on a long taper to get to the sump...and it was only returning flow from a mag3. I am about ready to sling this SOB out in the back yard and turn it into a glass puzzle. (So loud that I drained the tank into buckets last night so I couls sleep) My durso is the typical 'upside down J' configuration anything anyone knows about alternative ways to quietly get water to the sump?

Thanks!

I had a similar issue a few years ago with my son's 30 gallon.... A couple of things that worked for me:

1. I placed a sponge in the overflow box. This eliminated the flushing toilet noise and built up some water in the overflow container.

2. I placed a glass cover on top of the overflow box. This greatly reduced noise/ echo sound coming out of the empty box.

3. I reduced diameter of the tube entering my sump. The original tube was over an inch in diameter. As a result water flowing down the tube sounded like a waterfall..... Reducing the tube diameter made it sound more like a babbling brook compared to Niagra Falls.......

In the end I ripped down the tank.......

If I had to do it all again I would invest in a tank with built in overflows..... No matter how small the tank.....

Of course there is always Ambien to help you sleep..... Just kidding of course......


Good luck, keep us posted and get some sleep........

I have a straight standpipe that sounded like Niagara Falls - what I did was I inserted a 1/2" airline tubing into the pipe to eliminate the "vacuum" effect and it works really well (almost no noise)

Dont happen to have a pic of that do you? How far down the pipe does the air line need to be?

I will give this a try.

This seems to amplify the sound for mine???

3. I reduced diameter of the tube entering my sump. The original tube was over an inch in diameter. As a result water flowing down the tube sounded like a waterfall..... Reducing the tube diameter made it sound more like a babbling brook compared to Niagra Falls.......

Might have to give this a shot also...a little afraid of not knowing the flow through rate and subsequent flood that could occur if the pipe is not large enough to allow sufficient water to pass...

If I had to do it all again I would invest in a tank with built in overflows..... No matter how small the tank.....

This tank does have a built in overflow...the HOB models just take up too much room.

Thanks!

The only thing that will stop the rushing is have the air hole in the top of your stand pipe larger. Since you already did that, you need a muffle now. That is the tube coming out of the top. It doesnt need to be in the hole far at all. Basically just so it is in the hole, jam it in or use some silicone. I drilled my hole a little smaller and jammed it in there. I have about 2 feet of tubing coming off of it. If you put the end to your ear you can hear the gurgling noise, but it's pretty quite. Here is a picture of the top of my pipestand, not the best but you get the idea.

Thanks! I'll give this a try tomorrow and let you know.
