Upgrade time !

Hey guys,

I need some hell in tuning the herbie overflow I can't seem to get it silent and I'm not sure what I'm doing wrong is anyone able to give me a start to finish how to tune it

Im not sure if I have to much water or dialing it wrong or? My return pump is a DC controllable so I can ramp it up or down as well. Maybe I have to many variables

Do I just set my return pump then leave that and mess with my overflow ?

It seems that the noise is mostly coming from the water falling into the overflow not slurping or gurgling from the pipes

Thanks a lot
