Sand bed maintenance in a nano?

[Scuba Diver Gal]

We have a 29 g biocube too and your question was a timely one for us. My son is a beginner...so am I...

Do we have to vacuum off his rocks? We had a turkey baster in there today and a ton of debris went into the air when it blew on the rocks. Then do we strain that out? So much to learn...sigh...Also, our nassarius snails seem to stir the sand up a lot. That's probably enough?
