Yes and the movement of the fish help as well...the first picture is the dirtiest spot of my tank at the dirtiest time(when all the fish are not active yet). And the second picture is other section of the tank at that same time...a couple of hours after I turn on the light, most of the crap would disappear. Note this is over a year of not touching the sand...
