[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 cycles through 7 colors every 2 seconds (Red, Orange, Yellow, Green, Cyan, Blue, Purple), creating a soft and charming atmosphere. Designed for durability in various weather conditions. [Saves Time and Money] Reduces the need for chlorine by up to 85%, requires no external power or recharging, and helps reduce pool maintenance efforts. Keeps pool water clear with minimal intervention. [Healthy and Kid-Friendly] Helps reduce reliance on traditional chlorine, minimizing potential for skin, hair, and eye irritation. Easy to install and compatible with saltwater pools, chlorine pools, above ground pools, and indoor pools with lighting. [Fits Pools of All Capacities] Each unit covers up to 35,000 gallons. For larger pools, additional units may be used based on capacity. Clean the device with the included brush every two weeks and replace the copper anode every 1 to 2 quarters for optimal performance.
