for a fuge to work, you would want a slow flow rate to allow the algea to "clean" up your water and I don't think it matters if the reactor is before the fuge.
You can put many things into your fuge as long as the size is fine. Usually w/ large enough fuge, people grow algea in it such a cheato. Some even put live rocks/sands in them to further help w/ the the biological filtration. You will want a light that will help with the algea growth.
