Does it look like diatoms? Is the side that's brown get more light?
Try not stirring your sand for a week.

When you say it's not a new tank, is it less than a year?

Your bringing up the silica. The bottom sandbed is also the area of least flow and most noticeable.

If you stop stirring (keep vacuuming with water changes) is will probably stop. Try it and post back in a week.
