[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 copper pool floater can illuminate 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 manual cleaning. The solar pool ionizer helps reduce chlorine usage, requires no external power source or recharging, and assists in lowering pool maintenance efforts. Keeps pool water clearer between cleanings. [Healthy and Kid-Friendly] Reduces reliance on traditional chlorine chemicals, which may help minimize 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. Adjust the number of units based on pool size. Clean the device with the included brush every two weeks and replace the copper anode every 1 to 2 quarters for optimal performance.
