Does anyone know of a reason why every post in this forum and elsewhere on the net always uses some form of concrete to cover styrofoam backgrounds? I understand sealing the styrofoam to prevent pieces small bits and pieces from floating around the aquarium. Is it a weight issue because there are a multitude of ways to weight backgrounds without covering in concrete?
