I've got an overflow on the display (600gph), so yeah, that's happening ...

When I built my sump, I didn't make a skimmer chamber, and wanted to make sure that I was able to get the surface layer from the 1st chamber.
I get a fair amount of foam forming on the surface of this chamber and wanted to target it - only way I could think of was to pull from the top.
With the water level changing with evaporation I needed a way pull without cavitating the pump and ... Voila

Plus it gave me a chance to sniff methylene chloride fumes for a day

Ahh OK, makes sense to me now.
