No problems at all. We've had the saltwater pump for YEARS!! Our pools have been getting bigger and deeper as the kids got older. The saltwater pump will pay for itself before the end of one season. All you do is buy bags of pool salt ( around$4.50 ish per 25lb bag) based on the # of gallons in your pool. My pool takes 2 bags. I add salt probably 1 bag during the season. That's it! There's a chart for it with the pump. Dump salt into pool, let it dissolve and run the saltwater pump with the pump that comes with your pool. My youngest has VERY sensitive skin. NO problems with the saltwater. No chemicals to buy...AT ALL!! LOVE IT!! I wouldn't have a pool now without my pump.
This is sounding more & more tempting.
