Durso overflow gurgling? Need some tips

[LIreefguy106]

Hi all,

I'm just setting it up and did the leak test. During the test I noticed that the standpipe will not stop gurgling and the sump is heavily bubbling too. I can't seem to figure out why. I have a durso standpipe on a standard 90g reef ready tank. The setup is in a corner overflow and is the following:

-A 1.25" durso standpipe in one bulkhead (I have the hole drilled on the rope with a air valve)
-A 1.25" emergency standpipe in the other bulkhead
-The return is a dual over the back style.

The water level keeps fluctuating. I have a DC pump on the lowest setting and I also have a ball valve on the return and a ball valve on the drain. Any suggestions? I'll post a pic later when I get home. http://www.reef2reef.com/index.php?posts/2867620/

Maybe da return pump is to strong

If you have 2 drain bulkheads you should do something like this. Dead silent.
Here's a vid, not the best design I've seen. Google "Herbie overflow"

Thanks to those that responded. Figured out that the emergency and main drain lines shouldn't be connected. The echoing noise was the gurgling that I was hearing. Here's my setup that I had and I will be dedicating the emergency to its own separate line into the sump. Hope this helps someone else too.



The main is on the left.
The emergency is on the right

(I know I shouldn't have gate valves on the drain lines as it could lead to flooding but they were necessary as it is the only way I could remove my filter sock since the drain pipe fits deep inside the sock)

I just switched my durso to a gurgle buster setup and it's super quiet

I think it's most likely because you have tied both the emergancy drain and stand pipe together and it's causing back pressure for the air, therefore you're going to get the gurgle the way you setup looks like by the filter sock.
