When you say you will run them independently do you mean that the fuge will have it's own overflow or it will have one of the drains from the overflow like the picture you posted?
If you are using a single overflow and splitting the flow to two separate tanks that are not connected you are going to run into problems. Matching the overflow with the return of the MAG5 vs the Mag9.5 will be next to impossible. I tried this when I first got started. Disaster!
Your original drawing is a good one. The only thing I would change is remove the baffles from the fuge, drill that tank and put your PVC
connection to the sump (use a strainer in the bulkhead to keep macro from going through). I would make sure to have a ball valve on both of the drain lines so you can control or shut off completely either section as needed. I would have the other drain line empty where ever your skimmer is so that the water coming out of the tank goes into the skimmer before getting pumped back to the display.
As Neilan stated lower flow through a fuge is better. Longer contact time with the macro is a good thing!
