Solar Tempered Glass Aquarium Air Pump — Waterproof Oxygen Aerator for Fish Tanks & Ponds, Water Circulation

Important installation notes: Do not run the solar panel behind glass — place it outdoors in an unobstructed, elevated position for best charging. The solar panel is waterproof but must receive direct sunlight; position it so the panel forms a 40-degree angle to the horizontal plane and face it toward the sun at 12 noon to maximize solar energy (refer to solar water heater installation angles for guidance). Product features: The unit produces a uniform, fine exhaust (bubbles) with a high water-soluble oxygen rate. If you require greater exhaust volume, this pump can be used together with our nano gas plate to increase the amount of exhaust cylinders. Durability and mounting: The pump comes with a waterproof box that includes a hanging hole. For outdoor installations, either hang the box or mount it flatwise upside down to ensure protection. The enclosure is both waterproof and dustproof to effectively protect the internal lithium battery.
