Well the total flow of 3,027 GPH seems adequate. That'd give you ~35x turnover per hour. The positioning looks good to me otherwise, but again, I'm no expert and have no experience with closed loops or external water pumps. Maybe some else can chime in on that. (I use a big honkin' powerhead for my sump return).

The only other thing that comes to mind is to make sure your linear overflow length is adequate to handle the 2,107 GPH sump return. There is a calculator for this on Reef Central...if your not already familiar with it.
