Sunnydaze Decor 52 GPH Solar Oxygenator Plus with Battery Pack

Replenish the oxygen levels in your pond fountain with this convenient oxygenator. It uses solar energy or battery power to pump oxygen into the water. Comes with 2 modes: day and night mode. On day mode (green light is on), it will use energy supplied by the solar panel. On this mode, it will only function in bright and sunny conditions. Surplus power is used to recharge the internal batteries. On night mode, (push mode button, red indicator light turns on) the pump will only work at night. The batteries will power the oxygenator once the sun goes down. A fully charged battery will power the oxygenator for 6-hours. For best charge, please place the solar panel in a bright and sunny area and allow the batteries to charge for 8-hours. If you wish to switch it back to day mode, simply push the mode button and the green indicator light will turn on and pump will run with good direct sunlight.
