Be careful--all those places carry trichlor tabs, but the ones at most WalMarts are labeled "dual action", meaning they contain copper--which is a whole other ballgame when dealing with removing metals. You don't want to add copper to your pool, especially when you already have metal staining problems. Just check the ingredients on the trichlor pucks you buy, and make sure that copper is not listed as one of the ingredients.
