ah... if its FOWLR then it should be fine... stick to hardy fish and pick lighting to limit pest algae or have enough grazers, urchins, snails, crabs etc. Fish are not really that sensitive to Nitrates or anything so you don't need crazy filtration.
Honestly I wouldn't bother though, FOWLR isn't even worth the trouble to see some fish every 2 weeks, you can just go to the LFS every 2 weeks to look at fish
Just set up something in the apt. Show your gf clownfish or w/e is cute or just set up two tanks. His and her's.
