Overflow Noise

[ganjero]

How do you kill the overflow box noise? I'm not talking about the gargling ( I have a silencer for that) I'm talking about the waterfall sound. My overflow goes down like 4feet and the noise is very loud and annoying

Silencer? You've somehow silenced the sucking sound?

Yes it is pretty easy. You can buy something or build yourself.
Checkl this out http://www.rl180reef.com/pages/standpipe/standpipe-ken_stockman.htm



it works like a charm, but now I have the water fall noise, I was thinking in using a ball valve or maybe put an U on the pipes going down like the sink have underneath.


There is this one also, http://www.rl180reef.com/pages/standpipe/standpipe_frame.htm

Filter sock.

It's not really the water fall at the end, but the water fall inside the pipes. The sock doesn't kill this noise but rather the noise at the end (if the pipes are above water line)

anyone?

Do your pipes go straight down or are there elbows involved? What size return pump are you running?

 

[ganjero]

straight down and one elbow right before the sump

what's wrong with the durso suggestion?

right,

Check out this link, these work great

This is what I did, the noise was ....OMG, I was going to take down the tank if I didn't get it quiet.

The key is getting the holes at the right height. On my first attempt was without the bottom coupler, it drastically reduced the noise, but I thought it could be quieter, so I added the coupler, and voila..virtually silent. I had a bell on it, making it alot like a Durso, but it was quieter without the bell.

Worked for me, might work for you.

Correct me if I'm wrong... But, I think the problem he is trying to fix is the actual sound the water is making as it runs down the inside of the pipe... Not the gurgling sound the water makes as it enters the pipe...
However, I'm not entirely sure how to fix that particular problem. Maybe put a couple of bends in the pipe so the water doesn't fall so far all at once? I'm not sure...

Good luck though...

That was my problem too, not the gurgling, the water rushing through the pipes. I have two drain pipes 1.5" each reduced to 1.25 that drop straight down to the sump with no bends. I fixed the gurgle with a durso like standpipe. Raising the pipe, addresses the water entering the pipe and thus the noise created. I think

come on read a little bit better. I was the one that suggested the durso pipe to another person asking for that in my thread. Like I said in the first post the gurgling is not my problem, I Use a stockman silencer. The problem is the water running inside the pipes. I'm gonna try a few bend on the pies, like u turns and see what happens.

thanks for the suggestions

Could try getting rid of that 90* elbow, and perhaps using 2 45* ones, or switching to spa flex. Need a sweeping curve instead of a sudden one.

I happen to love the sound of crashing water. I installed a Durso and a drain pipe that can be silent but with adjusments on the bleed valve on the Durso and the stand pipe of the skimmer, I can constantly have the sound of moving and crashing water.

I used to live right on the beach at Padre Island when I was a kid so the noisier the tank, the better. I also think this aids in gas exchange.

Both the returns ripple the heck out of the surface and then one of the Koralia 4's is aimed up to agitate the surface even more. The overflow crashes hard and the skimmer stand pipe drops flat into the sump without any obstruction. The bleed pressure from the return pump that supplies the refugium also crashes fairly hard into the sump return area.

The more movement=more noise=more gas exchange.
