Looking to upgrade my pool filter, I have an above ground intex round metal frame pool 15ft across. I am trying to decide between a Intex 56673EG 14-Inch Krystal Clear Sand Filter Pump, 110-120 Volt with GFCI or the Intex 54601EG Krystal Clear Saltwater System.. anyone have any ideas on what works best?? I am leaning towards the saltwater system I think, it sounds like I may save money on chemicals? What does everyone think? Thanks!!
