Feature 11. This product is a solar-driven low-voltage DC product, safe and efficient (adults and children can be in direct contacting with the body for a long time), environmentally friendly solar panels, and the replacement cost is low. 22. Working principle: The high-efficiency solar panel that comes with this product generates direct current to stimulate the anode rod to electrolyze anions and copper ions into the water, so as to achieve the effect of cleaning and inhibiting algae quickly and efficiently. 33. 100% chemical-free, natural and non-irritating, high-efficiency and long-term protection of water quality. 44. Kill algae and reduce the need for chlorine: The solar pool ion can kill the algae and prevent it from returning. The device only floats in your pool and uses ionized copper to kill algae before it forms and takes over your pool. 55. It can treat 22,000 gallons of water and reduce the chlorine content.Material: Plastic + electronic componentsColor: WhiteSize: 23x17.5cm .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1*Swimming pool ion generator
