Last year I didn’t need to clean my cartridge filter at all till seasons end. This year I need to clean it again, third time. It slows down and causes a no flow on my SWG. This year has been terrible with seeds and tree blossoms. I have been using the hair nets in skimmer baskets and replacing every two days. Also my filter is oversized for my pool. Is anyone else find it out of ordinary this year or am I missing something when I clean?
