Sand bed maintenance in a nano?

[ToshAlexandra]

I've got a 28g nanocube I've had up and running about 14 months now. I havent' ever vacuumed my sand bed, have stirred it up a few times moving rock work or just to mix things up occasionally but thats the extent. My current set up wouldn't allow me to really vacuum much of it due to rock placement, but i could likely stir it up more frequently. Should I be doing this, or just leave things be? I've got 1 - 1 1/2 inch sandbed I would say.....

Any advice from the lil reef keepers?
