[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. The solar ionizer is suitable for above ground pools and designed to withstand harsh weather conditions. [Saves Time and Money] Reduces the need for manual cleaning. The solar pool ionizer helps reduce chlorine usage, requires no external power or recharging, and assists in lowering pool maintenance efforts. The copper ionizer helps keep your pool water clear even when you're away. [Healthy and Kid-Friendly] Helps minimize reliance on chlorine chemicals, reducing 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 copper pool ionizer is designed to cover 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 to maintain optimal performance.
