Introducing Harmony, the only cleaner that scrubs dirt from your entire pool, including the waterline, AND uses salt sanitation to remove bacteria from the water. Total pool cleaning has never been done so easily and so beautifully. Harmony requires no installation and operates independently of your existing pool pump, saving up to 50% of your pool electrical costs. Because Harmony distributes chlorine while moving all over the pool, the result is even distribution of sanitizer to every part of the pool. Even dead spots where algae blooms and dirt accumulates. There is no other cleaner or inline salt system alone that can do what Harmony does for your pool! It's the perfect balance of clean and chlorine.
