It seems like you could add a fuge, a bare bottom one at least fairly easily. All you need is a 25 watt clip on desk lamp, and a small ball of cheato. Great natural filtration. If you do not have a small wall in front of the pump I wouldn't add sand, because it will get sucked into the pump. You could pieces of rock rubble as a substrate to protect any inverts that would grow.
