Overflow Box is sucking air!

[cushingme]

Help! my overflow box is sucking air every few minutes and sounds like a toilet! I have tried placing an air hose in the out take tube. That made it so it wasn't doing it all the time. I tried turning down the flow into the tank but I don't want to slow it down to much!!! Any ideas of what else I can do?

Is it an external overflow box?

the "x" are just to show space

to the far right the tube is like 1" id and it is cut at an angle
to the far left it has a little stem and a little hole at the end of the tube maybe like 1/4" or may be smaller but it works just like a muffler dose on a car. i think hope this helps.

If you don't have the filter on, add a filter over the bulkhead. That solved our problem. If that's not enough search the net for Durso standpipe.

If you don't have a lot of room to install a Durso, check out the Stockman. It works well for me here...using two of them. Go to: http://www.rl180reef.com/frames.htm
and, at the top of the page, click the link for the compact external overflow standpipe.

I got a 12" piece of flexible hose and coiled it upwards and then straight out from my overflow line and that put just enough pressure into my overflow to stop the noise.

I used the durso in an over flow box made out of a plastic 5 g hex tank cut down. It works great, cept I did not put in a large enough bulkhead. So, I have to valve down my return a bit to avoid over flow.. will be cutting a new bulkhead soon..
durso works great and is easy to make and customize.
