I'm completely stumped... which probaly doesn't take much because I don't know much about pools.... yet. : ) I opened up my pool over the weekend. It was a green algae mess. And I've been cleaning the filter frequently. I have the green gone for the most part and am now at a murky blue but my filter has stopped working. When I take it apart and get it back together it will shoot water out strongly for about 20 seconds and then nothing. Do you think my filter grids are just so dirty and need to be completely replaced? Or is there a better way to clean them besides just spraying them off. If anyone has any tips and tricks I would love to hear them. Thanks!
