Plumbing Skimmer intake outside

[Bnagle]

I have an External reef octopus 5000 and was wondering what the best way to plumb the air intake outside?

Would I run it directly from venturi on pump or from the the tubing half way up pic air intake?

I would use the upper one so you could easily disconnect things. I'm sure there would be a downside to using the lower one, but it escapes me right now.
