Durso Hot Tub!!!

[Ruckus16]

I just plumbed my aqueon 120 with dual overflows and megaflow kit. Upon doing a leak test I discovered the drain into the sump is extremely loud. The drain from the right to left, longer drain, is very quiet. The drain on the left bubbles like a hot tub. I have tried adjusting the pump, adding a valve to the left drain, drilling out the durso hole, and adding airline in the drain. I'm going crazy. Someone please help.

How is this working for you? Did you find any solution? I am about to plumb the same setup...

maybe adding a picture of the drain at the source would help? vs in the sump
