on my marine tank i have an overflow which is connected to a hose which leads to the sump..

if i turn the power of the pump up on the one that leads to the tank it makes a gurgling sound..so i have to have it on a low l/hr...

how do i stop the gurgling sound ??

thanks Matthew

show us a photo so we know what we are dealing with here there a few types of overflow and each type has tricks to make it quiet

ok...will do tonight,

it is one of the ones with a glass sheet about 2/3rds uo the tank..the water flows over the sheet,through the tube into the sump...it is in the corner...i think they are called a corner overflow or something?

I know the gurgling sound that you're talking about. I haven't found a solution for mine yet and I'm not sure there is one. As far as I can deduce, the gurgling sound is caused by air getting sucked into the pipe when the water rushes in. After a little while you kinda get used to it haha.

I have seen people put air line tubing inside the pipe to allow the air through, that is if it is the water going down the pipe that is making the sound

yep..its water going down the pipe thats making that sound as far as i know,

so do i just chuck an airline tube in the hose so air can get through it?

something like that. I can't find the youtube vid but It was giving the air an alturnative route. so you may need a slightly larger pipe/ more than one airline tube sticking out the top and bottom. I can't remember exactly though but if you have some lying round it is worth a try

best solution

picture as i said i would...sorry it a rubbish,quick shot..

i will purchase an airline tomorrow if i need to,as i would not like to spend a lot of money to fix it.

I'm not surprised that's noisy. The water will be falling a foot or two there because you don't have a standpipe, it'll be a constant waterfall. Put a durso in and you'll cut a HUGE amount of noise out.

yeah like ira said but that wont cause a gurgling noise. so its only half the problem how many holes are drilled foin the back there? if its 2 your in luck

there is one hole which the tube is in if that is what you mean...my tank is only 1 ft tall so it is not the sound of the fall that i am hearing..

If you had a pipe coming at least half way up the overflow space you'll find a huge reduction in the gurgling sound.

Yep durso standpipe will fix this prob for sure, great invention, very easy to make :thup:
