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!!

I would do what TMZ mentioned. Put a ball valve on your return pump. And just tee off back to your sump. You can fine tune your pump this way.

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.
