That looks like how I've got mine set up. Sorry I couldn't get to your PM earlier, damn job keeping me from wasting time on the net. I like it, and it works on my tank! I believe mind is 2.5" from the back glass to the overflow side. With a set up like that, you could just place egg-crate on the top and it will keep the fish out!

Thanks! Do you have elbows inside your "channel" or is it just water straight to the bulkhead? Do you have strainers on your bulkheads?
