Plumbing question

[habs247]

Putting it to the folks in the know. Plumbing my new tank, laying out the pvc in some logical order and trying to set up a herbie overflow.

The orientation of my sump makes it really easy to make the primary drain just drop straight down into the sump. I'm guessing that's ok? I've read other posts where people recommend slowing down the water with 90 deg bends but those weren't herbie setups. Am I ok just dropping straight down into sump given that I'll be using a siphon?

Thanks in advance.
