If you use PVC, more than likely you'll add 90* and/or 45* elbows, horizontal PVC runs, going from the return pump back to your display tank. etc.. All of this creates the "head pressure" that reduces the return pump flow. Therefore, if your goal is 2800gph, you'll want a return pump that can exceed that to account for the head pressure. Does that help?
Yes that's helped there's going to be around 8feet of PVC from the return pump to the tank and would a Jebao jecod DCT6000 do the job?
they make rounded corner/angle pvc pieces (if that makes any sense) that help you avoid a lot of the flow restriction that you get from the hard angled pieces, id look at using some of them if you can. Im in the process of hard plumbing my 125 right now to run my fx5 off a modified pvc overflow system with inline reactors and sterilizers thrown in. the reefaquarium guide is super helpful too!

not really a matter of what angle, but what type of fitting, instead of using a hard 90 use a rounded 90 or a flexible corner fitting, they are better for the flow around the corner. using 2 45º in place of 90s can help with the flow a lot too, cuts the corner and makes the flow reduction less extreme
Looking at the 45° I could probably do it.
I recommend running two Jebao DCP 12000's and turning the power down on them, which helps with noise.
For my 220 I run two Jebao DCP 8000's and only run them on about 60% power each for a flow of about 1600gph total.
I recommend two for redundancy. In case one fails, you will still have half of the flow.
Also, the fine adjustability of the DCP over the DCT makes it much easier to tune the siphon in a herbie style overflow.

OK thank you I will have a look at the DCP.
So one more question for now I've got drain sizes what size return line?
