Advanced Solar Pool Ionizer made of high-quality copper ensures durability. The solar panel generates a low-voltage electric current when exposed to sunlight. Copper rods release Cu²⁺ and Ag⁺ ions into the water with the help of the electric current, helping to keep your pool clean. Automatically lights up at night when the switch at the bottom is turned on. Fully solar charged, it can illuminate for up to two nights. Automatically cycles through 7 colors every 2 seconds: red, orange, yellow, green, cyan, blue, and purple, creating a soft and charming ambiance. Suitable for various weather conditions. Reduces chlorine usage by up to 85%, requires no external power or recharging, and helps reduce pool maintenance efforts. Helps maintain clear water while you are away.
