The top plate is connected to the bottom plate such that the top surface of the bottom plate is spaced from the bottom surface of the top plate to define at least one chamber between the top plate and the bottom plate. The top surface of the top plate is in fluid communication with the chamber via the openings in the top plate. The scouring media is supported by the bottom plate within the at least one chamber.
