Protecting a Closed Loop Intake

[Scavenger]

I don't have a closed loop myself, but thinking about this I wonder what would it work like to have your intake for your closed loop inside your overflow box? This would keep a flow in the box where it is normally dead(ish) water as well as more flow for surface skimming the proteins.

This just an idea off the top of my head and I don't know if it's a good or bad idea.
