[Advanced Solar Pool Ionizer] The solar pool ionizer is made of high-quality copper to ensure durability. The solar panel generates a low-voltage electric current when exposed to sunlight. The copper rods release Cu²⁺ and Ag⁺ 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 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). The soft lighting creates a pleasant ambiance. Designed to withstand various weather conditions. [Saves Time and Money] Reduces the need for chlorine by up to 85%, requires no external power source or recharging, and helps reduce pool maintenance efforts. Keeps pool water clear with minimal intervention. [Healthy and Family-Friendly] Helps reduce reliance on harsh chlorine chemicals, minimizing potential 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 treats up to 35,000 gallons.
