I attached a very crude depiction of the media basket and how it COULD be set up in your tank. You likely wouldn't need it on both sides at the beginning of your tank, but once it is more mature and you have a higher bio-load you might need both sides. I would at least run filter floss on both sides throughout the duration of your tank though. This isn't your exact tank, but I believe it has the same setup.
