Need to have an air inlet hole at the highest point.

+1 on hole size . Also make sure water flow in and out at the same rate

It's not about the size of the hole it's about the air that escapes.

If the end of the drain goes right into the water then the hole at the top needs to be big enough for air to escape. If you have a sideways T at the end of your drain you can make the air escape there as well. It also helps so you won't have many bubbles going into the tank which cause salt creep and noise. At the top I have a cap only for noise and it's dead silent with the hole that I have. Also have no flushing sounds

Can you post a picture of where it enters your sump if you have that "T" ?

As requested* had to remove the skimmer to be able to see the back of the sump. No biggie, I purposely designed my sump this way.

So the water drains down and to the right. The tee also has a cap on it for more silenced noise. There is really a very small amount of bubbles from the drain itself and zero noise from it all. The pipe on the right is the drain from the frag tank above. I have been getting bubble from that but I haven't had time to fix it.

If you have any slope in the drain that goes up that can cause a problem. Maybe you should drill that cap at the T

Thanks for the help guys . it was a real easy fix i just had to adjust the return flow . sometimes we get ahead of ourself and forget the small things :suicide:.Heres the video of what it was doing [video=youtube_share;pxXKeUOCR_Y]http://youtu.be/pxXKeUOCR_Y[/video]

Yep that ones often overlooked, if your return is too strong for your drain size. Glad to hear it's resolved!

I had the same issue and wanted to avoid the flow rate. I inserted some air tubing into the durso inlet hole. You will notice a change immediately. The further you insert the tubing, the less noise will be noticed. Once you are satisfied with the sound, cut the tubing to the size you want with about a 1/2 inch sticking out. Make sure the max height of the durso, with the tubing, is below the overflow water line. Place a small o-ring on the tubing to keep it in place. I tried normal tubing and semi-rigid. I liked the semi-rigid. This may help and provide more flow which is more turnover.
