Good point. I had not thought of it like this. I was hoping to have a net 600 gph going through the sump. I guess it's just a matter of aesthetics for me. Where would I place a single return on a solid back wall? Maybe in the middle, with the two powerhead in each corner. Something to think about.

Tank with overflow is 69 gallons. I was hoping to have 20-30 gals of water in the sump ideally netting out at 100 gallons. I will have to be careful to leave enough to back siphon room in the sump for approx 5 gals. (40" tank width X 4" overflow depth X 6" height of full siphon below water level). That doesn't account for any back siphon of return lines or the volume of water held in the actual plumbing. I'm afraid I will need a pretty tall sump. This might exclude me from any pre-manufactured sumps out there. Thoughts?

Thanks for your feedback. Keep it coming.
