Using the power of the sun against pond algae - lily pad with solar cell and copper electrodes. The solar cell generates a low and harmless voltage when exposed to sunlight. This voltage is passed on to two copper rods. The conductivity of the water creates a current flow between the two copper electrodes and copper ions are released from the electrodes. The copper ions hinder algae growth. Suitable for pond sizes up to 5m³. For larger pond systems, simply use several ALSERO algae water lilies.
