[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 full solar charging. It automatically changes 7 colors every 2 seconds (Red, Orange, Yellow, Green, Cyan, Blue) to create a soft and charming atmosphere. Our 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 reduces chlorine usage by up to 85%, requires no external power or recharging, and helps save on pool maintenance and cleaning costs. The copper ionizer helps keep your pool water clear even when you're away. [Healthy and Kid-Friendly] Helps reduce reliance on chlorine, minimizing skin, hair, and eye irritation. Easy to install and suitable for saltwater pools, chlorine pools, above-ground pools, and indoor pools. Promotes a healthier swimming environment.
