What is the little section between LR and return?? Baffels??? If it's empty I would extend the LR section all the way to the return!! also what route will your water take, lr section then fuge, the other way around or will it be split between the two??
Edit: I see, I think!! How are you gettin water to the fuge?? it appears the baffel for the LR section is shorter so the water would go that way instead of into the fuge which is higher. I know I am brobably just being dumb and making it seem harder than it is, but please explain.
