Advanced Solar Pool Ionizer made of high-quality copper for durability. The solar panel generates a low-voltage electric current when exposed to sunlight, enabling the copper rods to release Cu²⁺ and Ag⁺ ions into the water, 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 atmosphere. Designed to withstand various weather conditions.
