Overflow plumbing

currently I have a simple pipe with holes drilled into the side standing straight up from the bulkhead in my overflow.

wanted to be smarter with an upside-down U type configuration.

what are the advantages? don't really care about noise--wondering if there is another advantage to the upside U, or if I should leave well-enough alone.

thanks!

It sounds like you are currently running a Herbie style drain. Do you have a second emergency drain? The other drain type you referenced is a Durso. They are common, but a properly rigged Herbie will be better for you in my opinion, and quieter too. I have a Durso on my 90g tank right now, but will be setting up a Herbie on my new 300g build I'm working on.
