Sand, Quad DE or Cartridge?
Today we went to the PB's showroom to pick out some things. My husband asked me to get some feedback from you all on which filter system you think is the best. He got an explanation of all 3 but is just not sure which one to choose. We have our choice of any of those and there is no additional charge based on which one we pick. Is the difference between cleanliness of the water that visible between the 3? Any feedback is greatly appreciated. Thanks.
