Help With Overflow!!!

Hello, Is there any water draining out? This type of overflow referred to as continuous siphon is notorius for breaking the siphon.After months of frustration and several floodsI fixed the three I had by putting them in a round container by the road and replacing them with a U tube type overflows.
While TMZ is right about the possibility of overflowing due to a loss of siphon, I don't think the type of overflow you are using is the problem at all.
Dont add a bunch of 90's to the return, you cant really control flow that way...you can restrict it a bit, but not control it.
If anything, add a ball valve - but that might decrease the life of your pump.

If you wan't to reduce flow from your pump, you can add a tee to the return with a pipe and valve flowing directly back to the sump from the pump and one to the tank. When you open this valve some water will flow to the sump reducing the flow to the tank, By turning this valve you can control flow to the display wihtout putting back pressure on your pump.
The overflow you have may work better ,if not reliably in my experience, with an aqualifter pump attached to the airline with the check valve protruding from it. This will remove air from the siphon area. To start your siphon you need to draw air through this line either by sucking on it like a strw or using a vacuum pump such as the one noted.
Good Luck

thanks guys, I ended up adding 2 90's, which slowed it down a bit, but hardly any, I'm thinking of adding another return pipe to the display tank, so there would be a return on each side.
This will slow the flow down a bit, and stop the one return from shooting water up under the trim.
I think we will get an aqualifter also just incase haha
Thanks for all ur help!!

You can always get an over-rated overflow (GPH) for instance if the overflow box is rated at 600GPH and your pump does 300, it will only draw and pump back @ 300GPH.
by looking at the pic of the overflow box, Is it sitting fully on the tank edge?
Seems like the screws can be lifting it a little too much. T and ball allow you to control the flow, i have a MAG 9.5 on a 46BF first it was all snow due to the high flow rate, it would draw most of the sump water before being returned by the overflow box back to the sump (my OF Box is a 600 GPH) I posted for help right here and did the ball valve, flow is great even with such a big pump.
I'm working with the PVC plumbing to fully use the MAG's flow setting two returns one on each corner and feed a Calcium reactor and a Phosban Reactor at the same time.
