Device, a water circulation device for circulating the pooled water, and a drug addition device for adding an effective concentration of an algicide to the pooled water, the lifting drive device is configured to prevent algae generation In operation, after raising the elevating floor to the water surface or above the water surface, the chemical addition device is operated to add an effective concentration of algicide into the storage water, and the water circulation device is intermittently operated at a predetermined timing. It is configured to control the driving of the stored water by circulation, so that the irradiation of visible light to the stored water due to the elevating floor is covered, the photosynthesis and respiration of algae are suppressed, and the growth of algae is suppressed. Effectively prevent Further, due to the short-time circulation and long-term retention, the concentration gradient of copper ions in the storage water is small, and the copper ions are uniformly present around the spores of the algae. The selective ingestion becomes impossible and both are ingested at the same time. As a result, a number of excellent effects are exhibited, such as that the spores of the algae cause cell destruction and the generation and growth of the algae can be effectively suppressed.
