Round Solar Oxygen Pump Aerator with 150cm Hose & Bubble Stone — 0.8 L/min, 3.7V 2200mAh Battery (1pc) for Aquarium Fish Tank Pond

Solar-powered floating oxygen aerator designed to boost dissolved oxygen in small ponds, aquariums and fish tanks. Runs on sunlight only — an energy-saving, environmentally friendly solution that needs no external electricity. Includes a 150cm air hose and bubble stone for immediate setup. Operation and performance: The unit cycles automatically — 10 seconds on followed by 10 seconds off — to aerate a limited area efficiently. Air output is 0.8 L/min while operating quietly at under 60 decibels. Easy setup: Simply connect the tube to the pump and attach the bubble stone, then place the device in the water; the round aerator will float and start working. Built-in battery: A 3.7V 2200mAh lithium battery stores solar energy so the pump can continue to operate during the night. Supplied as 1pc.
