The reason the rock work becomes unstable is from burrowing inverts and fish making the sand under the rock unstable. If you add your sand first just push your rock down through the sand until it touches the bottom of the tank. Then you'll have nothing to worry about. I recommend adding the sand first. It just makes everything easier.
