I got to spend some more time looking at your design. Your design is almost exactly like what I was thinking of doing other than 2 items.
1)I was going to put the pump to feed the skimmer in the section of the sump with the overflow.
2)I was planning on running 2 outputs from the 4 way to the front of the rock and split them with a "Y"and run the other 2 to each side of the tank and have flow from each side.
Does this make sense and would it work ok? [/QUOTE
Brady, regarding #1, there isn't anything wrong with putting the skimmer intake pump there. In my case, the sump I got has a plastic cover and light fixture that sits over that center section (refugium) which is where I keep my macro algae and pods. If your sump doesn't have the cover or if you plan something else in there you can certainly do that. I like the idea of getting the water to the skimmer after it's gone through the filtration socks, through the sponge and then into the skimmer, and also like how I return the water from the skimmer back to the beginning of the sump, and it has to go through all those steps again before going back into the tank.
As far as #2 goes, I am most certainly not the most experienced person to weigh in on this, but I venture to say that I don't foresee any issues with it. I would make sure to equalize the pressure going to each by having relatively symmetrical or equal plumbing on each, but other than that, just be careful not to have too much back pressure - which I think you would avoid by not having to many elbows and not reducing size/flow too much.
I do recommend you ask someone who knows a bit more than me for the second, but I'm glad you're designing your system in a similar fashion. Worked well for me!
Good Luck and let me know what you end up doing!
