[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 light up for 2 nights after a full solar charge. Automatically changes 7 colors every 2 seconds (Red, Orange, Yellow, Green, Cyan, Blue, Purple), creating a soft and charming atmosphere. 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 recharging, and assists in pool maintenance. Keeps your pool water clear with minimal effort. [Healthy and Kid-Friendly] Helps reduce reliance on chlorine, minimizing potential skin, hair, and eye irritation. Easy to install and compatible with saltwater or chlorine pools, above ground pools, and indoor pools with lighting.
