Seems I have algae in my tank. The pre-filter gets covered in a black film in a couple of hundred miles of driving which is wrong. This continually restricts fuel supply. I have been changing them continually. I decided to dose the tank with a biocide (FPPF Killem) the other day. I still see a black film forming on the pre-filter interior screen. I thought the biocide kills the algae preventing it from "sticking" to mesh? I guess it's NOT like shocking a swimming pool with chlorine. Will the dead algae from the tank eventually make it to the pre-filter in non-clinging chunks which can be removed by changing the pre-filter? I have had the tank screen out which did have a covering of algae so I replaced it, but that was two months ago.
