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?
No way the 6000 will move that water with 8 feet of headloss. Just get the 15000 better to have to much flow and dial it back.
Not sure if there is a chart like this for the dcp


I always try and use 45's where i can
I think they are called sweep 90's i use some on my last sumpthey 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!
Hmmm, what's the gph on paper? I want to say that's not going do it as I don't recall that's anywhere near 2800gph. I believe you should be looking at 12000 or 15000?
+1
BRS did a test between 90* and two 45*. The results showed two 45* was not any less restrictive, and, in at least one case the single 90* had higher flow. IMO, get a pump that is rated higher and account for it that way. Gives you more flexibility as to how you want to run your (PVC) plumbing - for function and for aesthetics (if you care about that).
That interesting i always thought using two 45's would be less restrictive too
