I use a gravel vacuum and vacuum all the sand to its full depth on all waterchanges. The sand is only 1/2" deep.
If your sand is more than 1/2" deep and you do not regularly vacuum it you do risk exposing black anaerobic areas and releasing hydrogen sulphide. So if you haven't vacuumed, but you want to, you have to start slowly by only going through the top 1/2" of the sand, and continually going a bit deeper on each waterchange. I've had tanks with up to 6" sand beds that I vacuumed to their full depth, but it was done regularly and no anaerobic areas were allowed to form.
