Okay ive done alot of research on this subject lately. it would seem that if you have a shallow sand bed that is less than 3 or 4 inches deep you should definitely vacuum. a sandbed that is shallow will not support the life necessary to clean itself. I personally vacuum my display tank which has a three-quarter inch sand bed with a gravel filter into my sump/fuge through a filter sock or two. I do this once a week.
A dsb should not ever be vacuumed. 4" or more with fine sand will hold suffivient life to clean itself. But only when done right. Animals such as sand stars and sifting gobies are a huge no no for dsb. Although they will stir your sand, they do not eat the harmful nutrients in your sand. They actually eat the worms, bugs, and other small life that do eat these nutrients. :-( I prefer to use a dsb in my refugium which is never touched accept harvesting plants. And the life is amazing!
