I'm with reef_guru on this. I have a deep sand bed and I dont do anything to it, my clean up crew keep the top layer clean so the sand is always white. As time goes on you can see the layers in the sand, it's actually pretty neat!
A word of caution though, my old tank had a sand bed of around 1.5inches, this is in the range of not really being a shallow or a deep sand bed and it basically turned into a nutrient sink after a year or so! Mind you I cleaned the sand every 3 to 4 weeks and obviously that wasn't enough.
