I suggest you put the coarse gravel on top, the fine gravel in the middle and the cotton balls on the bottom. The less gaps in the material the more dirt will get trapped. The coarse gravel will take a small amount of the dirt out. Then the fine gravel will take out more and finally the cotton balls will most likely take out the rest leaving an evenly distributed amount of dirt in each layer. If the cotton balls are on top then the dirt would fill the cotton balls and some of it might still come through then the layers of gravel may not be effective to such small pieces of dirt.
