Just got our pool filled and the pump running, now I am not sure what to do. I know I need to add chlorine, but I don't know how much and the pool math calculator doesn't seem to like the 0 reading I put in for chlorine. Everywhere else I read says that I should shock it. I wanted to get advice here first. I just have strip tests right now but will order a test kit. Thank you!
