Water level is too high in your over flow box. Water is going down your secondary drain at a fast rate (instead of slow trickle) a couple things can be done. 1) raise secondary and emergency drain
2) open primary drain wider
3) lower return pump speed

Slowly turn your primary gate valve 1/4 turn at a time (waiting a few minutes between turns) until the water level in the overflow is about 1/2 up the horizontal part of the secondary drain's U. If that means the level in your overflow is low enough to cause noise you will need to raise the secondary drain....it's the one that sets the water level in the overflow.

+1 on this

It's slow going, but I'm starting to dial it in 1/4" inch turn at a time. At least at the end of this project, I have a brand new sump and skimmer to go with it
