The noises, man, the noises!!!

I've dialed down the drain, I've slowed the return to 70%. And instead of gurgling toilet, I have a gerbil chewing on pvc noisies. Pinching the airline doesn't help. In the sump a few bubbles come in the water line in the over flow is a perfect 1/2" above the top of the bulkhead ring. NOTE: my overflow is not a bottom drain, it's a side drain. It's so close to the quietness of a full syphon...

Is this a new drain setup?

Take the gerbil to the dentist and pull it’s teeth.

New as of 2 weeks ago. Had a similar setup just a much shorter run, into the cabinet vs the basement as it is now. That was loud but on an ac pump and a ****** ball valve couldn't really tune it in. When I had my old old not drilled set up, but a diy full siphon, it was so quiet. Like my cat farts louder than my tank, until the skimmer kicked in.
Missing a piece of my airline rig, the friggin valve for the airline has disappeared and I went to few (3) diff stores and nobody's got one.

Sure thing. But then what do I do tonight? Too late to get a new gerbil...

Agreed! Amazon Prime is so over- rated.

Not sure the exact science nor physics.... but drains do get quieter over time

Post some pics of your drain setup and sump so we can see these gerbils in action.
