Last summer we ran a 14' x 42" ProSeries pool with its wimpy pump and skimmer set-up...we're in Phoenix so with the 115+ heat we had a heck of a time with chlorine and other chemicals. We switched to the BBB method which was better, but still a lot of work. This year we're planning on buying a 16' by 48" Coleman pool and buying a better pump/filter set. I'm looking at saltwater systems and also sand systems, and found one that's both in one unit. I really like the idea of the saltwater system (we had an in-ground pool with one years ago) and wonder if I need both that along with a better sand filter, or just that. I have tried to research this online and just feel lost. The reviews on Amazon basically say each type is great and you need it.
