Bean animal overflow question

[roggy23]

First pic is my drains, second pic is my pump controller at the lowest setting, 3rd pic shows the inside of the overflow box..
Note that my secondary drain height is 1.75” higher than my main drain inside overflow box… why is it that when I increase my pump speed the drain flows more and I can’t ever adjust it with the gate valve to make it quiet again? My tank is 180 gallon 6x2x2. Why can’t I add more flow and it remain quiet?

How much flow are you generating with that pump? It's going to be guesswork/trial-and-error without knowing that.

Measure the amount of water flowing through the drain(s) and time how long it takes to fill a container of a known volume....do the math to calculate GPH.

Are your drains 1" diameter PVC?

Is this a new system? Is it possible there's a clog?

1” drains, not a new system. I just wanna be able to up the speed and maintain a quiet drain but can only manage this at the lowest settings … which I think is about 450gph
