Pool owner for 10+ years but new to TFP method, always just used tablets and granular shock "as needed", oops!! Moving to bleach now. Chlorine has been running crazy high for months and couldn't get in normal range, scaling on glass tiles and copper spouts. I knew something was screwy but everything looked fine other than high chlorine with a basic test kit and when the neighborhood pool store would check so here I am, just tested with Taylor 2006 kit and things are screwy! What now?? Do I have to drain the whole daggum pool to get the CYA down? Can I overfill a little at a time, do I let the munchkins have a splash party?
