I did it. Just a two-circuit one. No problems, the diagram is here. Most recommend making the external lower bend slightly lower than the internal one. But it works for me as it is. I'm attaching a photo of my mistake; I couldn't understand why the circuit was airlocked until I reviewed the diagram again at 1 AM.

Good afternoon! Could you please tell me if your overflow is very noisy?

Good afternoon. I installed plugs with holes on the end pipes (the highest ones in the photo) - there is no noise at all.

Phyllis

Thank you!

Denise

And how are things with the oil film?

I don't have the skill, or I don't notice it. There's another nuance here - the overflow works to drain water from the sump into the display aquarium (the sump is on top).
