POOL FROGî Mineral Hybrid combines two technologies; the FROGî EPA approved silver formula and chlorine generated by salt. No difficult programming or hard to understand readouts. Yet the technology is one of a kind using low voltage with direct power to every other plate inside the Cell. We call it Super Charged because it provides greater efficiency and performance. POOL FROGî works so well it offers a 7-year warranty on the Generator, Control Panel and Cell and a 10 year warranty on the Cycler.
