Just saw something in another thread about blue streaks on plaster and one of the proposed causes was the presence of copper in a high chlorine environment. This made me wonder if some of my blue green issues are not a direct result of the 6 bottles of copper algaecide the pool store sold me on. I am pretty sure the copper is the reason for the staining on my steps and I wonder if it is causing some of my other headaches. I know for now to just keep on the slam, but is this something I should be concerned with also?
