It could be diatoms. Take one out and see if it comes off really easy. If it does it is diatoms.

If the tank is less than 9 moths old just give it time and it will go away. If the rocks are less than 9 months old same thing. If it is an older tank then it may be an issue of circulation. It could also be a silica ornament that you have added to the tank recently that the diatoms feed off. I added a painted and fired ceramic ornament and for the first 4 weeks it grew massive amounts of diatoms because of the glass finish.

Give it some time and make sure that you have some circulation around it. If there are any dead spots they will get it a little worse. My BN plecos ate it and I think otos will eat it so it might be a good thing in the short run.

I read somewhere that if your rocks turn brown, it could be a lack of oxygen in the water.
