[Advanced Solar Pool Ionizer] The solar pool ionizer is made of high-quality copper to ensure durability. The solar panel of the copper pool ionizer generates a low-voltage electric current when exposed to sunlight. The copper rods release Cu²+ and Ag+ ions into the water with the help of the electric current, which helps keep your pool clean.

Our solar ionizer for above-ground pool is suitable for various weather conditions. [Saves Time and Money] Say goodbye to hard work cleaning.
