    Will a new Polaris 3900 Sport work with existing return?

    I am considering replacing an old Polaris 180 suction cleaner with a Polaris 3900 Sport (will use existing booster pump). The existing return opening is about 1 inch and is only a hole in the side of the pool so it has no threads in it and the old Polaris 180 connector/fitting apparently was...

    What is happening to my plaster?

    Now that I have taken Step #1: "practice with your testing, trust your numbers, forget about the pool store, trust TFP", I would like to know if I have a real problem with the pool surface. Although the water continues to look clear, I see what looks like dirt but it won't brush off. FC: 4...
