FROG® 01-14-3288 @ease® Floating Sanitizing System - FROG @ease combines our sanitizing minerals with SmartChlor® Technology to kill bacteria two ways. The result is fresh mineral water that’s silky soft with far less odors and the easiest water to maintain because it’s self-regulating. It knows when more sanitizing power is needed and automatically delivers it. When you need to do something, it flips over.
