[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 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 to withstand harsh weather conditions. [Saves Time and Money] Reduces the need for manual cleaning. The solar pool ionizer can reduce chlorine usage by up to 85%, requires no external power or recharging, and helps lower pool maintenance efforts. Keeps your pool water clear even when you're away. [Healthy and Kid-Friendly] Helps minimize the use of chlorine, reducing the risk of 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 treats up to 35,000 gallons. Adjust the number of units based on your pool's capacity. Clean the device with the included brush every two weeks and replace the copper anode every 3 to 6 months for optimal performance.
