Splitting overflow and making return manifold

[jgraz]

Since I'll be add a new sump soon I'm considering cleaning up my plumbing and making things more efficient. The problem is I'm dump when it comes to this. I am thinking of setting up the sump with the return in the middle, therefore I would need to divert overflow to the skimmer and refugium. I am also considering making a manifold from the return pump to supply my reactors as well as main return. I can picture it all in my head but I have no idea how to put this into practice. Can someone help and explain this to me. Also pictures of your systems would be awesome that way I can see what is going on. My sump will be a 40 breeder and the DT is a 90RR with single overflow. Thanks in advance.
Here is a pic of the sump I'm planning. If I decide to split the return then ill switch the fuge and return sections
