I use posterboard and change the bockgrounds pretty often. My fav so far is a dark blue.
painting the back of your tank w latex paint is fast, cheap easy and a snap to take off. no PITA involved. Well a PITA if you have a big tank and can't move it to access the back.
--personally if the tank is scaped well and planted well I really don't notice the background very much. I always notice equip that is visible
