New Water® Chlorine Systems for Pools The New Water System is on constant watch, dispensing low levels of chlorine to control bacteria and provide sanitizing protection for your pool. Once you've determined the correct setting for your pool just set it, then forget it! There are two parts to the New Water Cycler System: The New Water Cycler acts as the "water treatment center," controlling the flow of water through the system. The pre-filled Cycler Pac fits into the Cycler with no measuring, no lifting heavy buckets and no over-powering chlorine fumes. New Water Features: Convenience: the pre-filled Cycler Pac means no more touching or smelling chlorine. Precision: The control dial precisely meters out just the right amount of sanitation for each pool. Longer Lasting: trapped air in the upper part of the Cycler Pac keeps the chlorine dry so it lasts longer with less consumed each season. Reliability: Water cycles through only a small amount of chorine for more uniform and reliable output.
