Just set up my sump for my new 120. Drain is gurgling like crazy. I've tried everything I know to do. Reduced the return flow and/or add a u shape thing into the sump drain line. It seems like the water level in my overflow box is too high, should I take out some water? It seems like I just can't get the durso to not suck air....??
Can't get rid of sump drain gurgling

Is there a hole in the top of your durso standpipe. I just happened to be watching this video a day or two ago. http://www.vividaquariums.com/sumps-pumps.asp
Your durso needs an air hole on top.
I would drill a 1/4" hole on top of your durso. See the last step in the link below

Not sure, but it also looks like the standpipe is too short. My understanding is that the water level going in should be about in the middle of the horizontal pipe connected to the 90
Do you have a ball or gate valve along the overflows line anywhere? I had to tune mine with a ball valve to get it right. I believe durso's need to be restricted shortly after the bulkhead (valve/smaller pipe) to work properly. Also try bigger hole in the cap and maybe even insert a short length of airline tubing down and play around until you find the right height. Hth
I believe you are correct. What you here is the drain becoming a full siphon and then it gurgles when there is no water left.
Do you see the water in your overflow lower dramatically for a few seconds and then ill back up?
The drain connected to your sump. Is it under water?

I've managed to keep a consistent flow with the return flow amount setting I have right now, but at any other setting the up and down water level thing does happen. It gets quiet for a second then rushes water through. Right now the top of the cap on the standpipe is the same height as the overflow box. You're saying it should stick out of the top and be taller than the tank? Should the water level be above or below the returns?

When I had a durso setup I had this problem until I cut the flow WAY BACK with a ball valve on the output of my return pump.
I think that you still have too much flow from the return pump.
At the time, I had a Mag 9.5 on my old 90g. I had the valve about 1/2 off. It was then mostly quiet.
On my new 156g, I used "Herbie" drains. Is that an option? My tank is so quiet that I often have to make sure it is running...and it always is!
Hope this helps

Try this, works great on both my 240's.
Replace the durso fittings at the top of your stand pipe with a fitting that looks somewhat like a bowl. I use a 2"x4" coupling, might be a little different for your use. I then put a 1.5" strainer or whatever size strainer in the bowl to break up flow. It just lays on it's side in the bowl, but is too big to go down the hole. On top of the bowl, I place a drainage grate, like from a shower that perfectly fits the top of the bowl. I had to trim the interior rim of the grate so that the strainer did not prevent it from closing all the way. I also looped a zip tie in the grate to make it easier to remove for cleaning every few months.
I thought everything else a just too complicated. I barely hear my tanks when standing right in front of them. A slime/algae coating also helps to deaden the noise over time but even when I clean the grates, it remains quiet. The loudest part of my tank now is when the auto top off kicks in and the water drips into the sump for 30 minutes or so.

Here is what the coupling looks like:

Here is the grate that goes on top:

And the strainer I just lay in the bowl:

It is pretty easy and cheap to try it out.

Ends up looking alot like this, but with more of a bowl like fitting on the bottom and the strainer just lying on the inside to break up any circular flow.

Mine is just under the water line. In fact, the way I see your stand pipe, you might just be able to remove the Durso and see where that gets you. The less water fall the better. If you can't find the correct bowl type fitting, you might need to size it up with another coupling. I am not sure you can get the grates smaller than 3" or 4", so that will be the pacing item. Also not sure about the room in your overflow, but you can determine that.
