Here is a shot of testing just before I was ready to stock. Kinda gives an idea of how it works:

I'm sorry that I didn't take a picture of the undergravel plate before I burried it but it is about 1/2" tall and about 7" in diameter. I cut a round hole in the plate just above the return bulkhead and inserted a short length of 3/4" pvc which sits directly on the the return bulkhead and prevents the filtered water from mixing with the unfiltered water under the plate. I glued some "efi substrat" filter media around the rim of the exit in order to try and hide it a bit better and then poured crushed coral up to the level of the exit. That's pretty much it.
