Is this a new tank set up????? I thought your 500++ was up and running for a while?
If its new like the others are saying could be diatoms and nothing to worry about. Give it some time to work its way out of the system.

Cyno when it first starts out somethimes is just a dusting and it does not look bad but over time it will grow into the large mats of crap on the sand bed.

Have you tested you water for PO4 and Nitrates?

"The brown discoloration on the sand is probably diatoms which should go away as the tank matures."

That pretty much sums it up.
