Features 1Energy Saving and Environmental ProtectionSolar pool ionizer is a small, strong, durable polymer disc with a replaceable copper rod anode on the bottom and a solar panel on top. No additional charging required. 2Sustainable Pool Clean and MaintainCopper pool ionizer with electric current powers the copper rod anode below, and the energized anode releases copper ions into the water. The ions pierce the protective outer membrane of algae and bacterial cells, disrupting the balance of enzymes, inhibiting bacterial growth and disinfecting the water. 3Easy to UseThe pool ionizer is simple and convenient to use, just float it in the swimming pool. The anode/u0027s ionization is activated under the sun/u0027s irradiation. The ionization process inhibits the growth of microorganisms and reduces harmful minerals in the pool water.

Absorb harmful substances such as calcium and iron. Solar ion generators kill harmful microorganisms and protect the healthy balance of water organisms. You no longer have to worry about your hair, skin, and glasses being harmed by chlorine. Low Consumption and No Harm to HumanPool ionizer for above ground and inground pool is eco-friendly. Solar panels generate low-voltage current when exposed to sunlight, which is completely non-toxic and harmless. Safe and efficient to use.
