Looks great! Nice strainers. I know those work perfectly and create zero dangerous suction at their surface. Use a threaded bh so you can unscrew and replace them easily for cleaning.

If you aim a couple of the cl outputs upward slightly toward the surface, you won't have any need for Sea swirls. (I've heard that they don't run reliably for long periods...but I've not personally used them) My water surface boils from two outputs on the bottom of the tank.

You mention "a couple of Reeflo pumps"...but only have 4 holes in the back wall? Two holes for the strainers, leaves only two holes for tank inputs?

Consider using two of the top/corner holes as sump returns (over the top will prevent back draining in power failure). Use the other two top/corner holes as part of your CL's. Even though you are a bit short on holes, you could still put an OM-4way on one or both CL's. You'll just have to connect two outputs into one, but you'll still get benefit of the current mixing they can provide.

I like your idea of placing coral where the food appears to be. It is going to test your patience to wait that long to add corals!
