Hey all
I am just setting up 125 gallon reef tank (fresh water). 6 foot long corner overflows.
I have three-quarter return lines. Danner 12 pump (1200 gallons per hour ). 4.5 feet of head.
The overflow start says one and a half inch sanitary tee that necks down to 1 inch pipe, it goes to a 1 inch bulkhead that goes into the sump. I went with the sanitary tea just to try to have the water flow a little bit nicer into the pipe hoping to keep the flow levels off while reducing the noise. Maybe I made a mistake?
If My overflows pull a full siphon, it overruns my pump and begins to gurgle as the overflow fills up, because it looses full siphon.
I drill the tiny air hole in the top of my caps to prevent it from pulling a full siphon. I am still getting a little gurgling sound and the water level inside of the overflow fluctuate slightly on my right overflow intermittently.
I could mitigate all of this by screwing a half inch barb fitting to my intake of my pump. I would rather not do this because I would like to keep the flow rate where it is.
What are my options? Should I install a ball valve on One of my 1 inch overflow pipes? If I install the ball valve, could I regulate that side to force a full siphon on the other side? The only problem I see with a full siphon on one side is the water level inside of the overflow goes down considerably and then the noise from the falling water inside the overflow goes up.
Another possible option is regulating the flow from one overflow with the ball valve just slightly to try to keep the overflow volume consistent. Maybe this will help alleviate the gurgle.
As always, thanks for the insight.

Edit: None of this is extremely loud by any means. My wife is just inquiring. It is the first time we are using some style filter in the house. I am just trying to make it as good as possible.
