Maybe the chlorine dosage was not appropriate. It have to be adjusted with the load in your system as well as the type of filamentous bacteria that you have. You have many article on the subject on internet. I can suggest you one to help you with your problem. http://www.dec.ny.gov/docs/water_pdf/drrichard1.pdf
