Gurgling in Sump

[MarkF]

I just set up my 75G RR tank last night. I used PVC to run the lines. I have a Durso in the overflow box.

I have the Drain line running across the top of my sump (L to Right) with a T down to the skimmer section on the Left Side and to my Fuge which is on the right side. The pump return is in the middle.

I used a T on the end of the line above the Fuge, leaving the top open and the bottom is under the water line. I am getting splashing and gurgling from the Fuge section. The pipe is also under the waterline in my skimmer section.

Should I just use a regular 90 instead of the T? Do I need to be above the water line to avoid the gurgling?

I tried to draw a picture.

Put a 90 or a T at the end of the fuge drain right at the water line so that the opening is half under water and half out of water. This will allow the flow to go accross the water and not drop into the water (causing noise).

What Pump are you running? Maybe to much GPH?

The noise (and splashing) is coming from the open top of the T which is out of the water, the bottom of the T is in the water. The T is sideways like this --|.

I've used this pump for years on this tank when it was set up for Cichlids. Only difference is now I plumbed the drain in PVC instead of flex hose. It a Mag 5 equivalent.

Has to be something about this new setup. I'll try the 90 instead of the T when I get back home.

this sounds right. A line under the water or the lack of a consistent downward slope on the drain will cause gurgle and sometimes flush like a toilet.

Gtstricky - I will also try the opening half in half out with another 90 or T.

Do I still need the T at the end of the line which is functioning as an airstack? Or can I use a 90 there?

Just an update, the problem was the T at the end of the line, I used a 90 and everything is good.
