[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 pool floater can light up for 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. Suitable for outdoor use and designed to withstand harsh weather conditions. [Saves Time and Money] Helps reduce the need for chlorine by up to 85%, requires no external power or recharging, and reduces pool maintenance efforts. Keeps your pool water clear even when you're away. [Healthy and Kid-Friendly] Reduces reliance on chlorine, helping to minimize skin, hair, and eye irritation. Easy to install and compatible with saltwater or chlorine pools, above ground pools, and indoor pools with lighting. [Fits Pools of All Capacities] Each unit covers up to 35,000 gallons. Adjust the number of units based on pool capacity. Clean the device with the included brush every two weeks and replace the copper anode every 1 to 2 quarters for optimal performance.
