[Advanced Solar Pool Ionizer] The solar pool ionizer is made of high-quality copper for durability. The solar panel generates a low-voltage electric current when exposed to sunlight. The copper rods release Cu2+ ions into the water with the help of the electric current, helping to keep your pool clean. [Automatically Switch 7 Colors] Automatically lights up at night (turn on the switch at the bottom). The unit can illuminate for up to two nights after a full solar charge. It automatically changes between 7 colors every 2 seconds (Red, Orange, Yellow, Green, Cyan, Blue, Purple), creating a soft and charming atmosphere. Designed for use in various weather conditions. [Saves Time and Money] Helps reduce chlorine usage by up to 85%, requires no external power or recharging, and reduces the need for frequent pool maintenance and cleaning. Keeps pool water clear even when unused for periods. [Healthy and Kid-Friendly] Reduces reliance on harsh chlorine chemicals, helping to minimize skin, hair, and eye irritation. Easy to install and compatible with saltwater pools, chlorinated pools, above ground pools, and indoor pools with lighting. [Fits Pools of All Capacities] Each unit covers up to 35,000 gallons.
