Operating Principle: The efficient solar panel provides direct current to the built-in anode rod, which electrolyzes anionic and copper ions and releases them into the water. This quickly and efficiently breaks down the outer walls of bacteria and algae spores, achieving sterilization and algae inhibition. It is 100% chemical-free, efficient, and environmentally friendly, non-irritating, and a natural way to maintain water quality for a long time. Features: This floating pool purifier is powered by a solar panel located on top of the unit, making it self-powered, eco-friendly, and easy to use. The ultrasonically welded body prevents water leakage or moisture infiltration from damaging the internal components. The integrated 230g anode rod has a long lifespan, effectively killing bacteria and inhibiting algae growth. It also collects unwanted minerals such as calcium and iron to soften the water. A natural and safe way to purify water, chlorine-free, non-irritating, odorless, and maintenance-free. Economical and energy-saving. No skin irritation, bleach-free, odorless, safe, and environmentally friendly. Widely used in outdoor ponds, swimming pools, spa fountains, and landscaped pools.
