Working principle: The efficient solar panel can provide direct current for the built in anode rod to electrolyze anion and copper ions and release them into the water, which can break the outer wall of bac-teria and algae spores quickly and efficiently, thus achieving the effect of sterilization and inhibition of algae. It's 100% chemical-free, efficient and eco-friendly, no irritation, a natural way to maintain water quality for a long time.<br> Features:<br> Floating pool purifier powered by a solar panel placed on the top of the purifier, self-power, eco-friendly and easy to use.<br> Ultrasonic welding body to prevent any water leakage or moisture infiltration from damaging the internal components.<br> The built-in 230g anode rod has a long lifespan, can effectively kill bac-teria and inhibit algae breeding.<br> Can also collect undesirable minerals such as calcium and iron to soften the water.<br> Natural and safe way to purify water, chlorine-free, no irritation, no smell, and maintenance free, economical and energy saving.<br> No skin irritation, no bleach, no smell, , safe and environmental protection.<br> Widely used in outdoor pond, swimming pool, SPA fountain, landscape pool.<br> Specifications:<br> Material: ABS<br> Cycle time: 2 hours<br> Power: 2W<br> Solar panel: monocrystalline Solar panel<br> Inlet diameter: 300mm<br> Outlet diameter: 300mm<br> Item Size: 16 * 16 * 16cm / 6.29 * 6.29 * 6.29in<br> Item Weight: 560g / 19.75oz<br> Package Weight: 743g / 26.2oz<br> Package Size: 20*19*18cm / 7.87 * 7.48 * 7.08in<br> Packing List:<br> 1 * Solar Pool Purifier<br> 1 * Brush
