I just added water to my latest tank. I used a similar sump setup only having the inflow coming into a seperate chamber that held my heater and protein skimmer - then a baffle, my fuge, then a baffle into a live rock rubble area with my return pump. I also have the intake area with the protein skimmer having some rubble.
I have a wet/dry setup with my 125g and I am not pleased with its performance and I will be switching it over to a rubble/fuge setup shortly
