Noisy Drain Line

[darb]

I don't have any pictures of the actual setup atm; it is no longer my tank but a friends. Below is the type of overflow that I am referring to.



I will snap a photo of my 90 tomorrow as a better example, it is configured exactly the same way.

Yes, the tank is up and running and against the wall and with no chance of an ato in the foreseeable future.

Really not looking to change to a Herbie.

I was hoping that someone might have a few suggestions to deal with the situation as it is. Like I said, it is noisier than the same setup on my 90 RR and I swear that it wasn't that noisy before. Although it got replumbed and I was running flex PVC which may have just been insulating the noise better.
