Solar Aeration Pump — Ultra-Quiet Lithium Battery Air Pump for Aquariums, Hydroponics & Fish Farming (High Efficiency)

This solar aeration system charges an internal lithium battery and delivers quiet, efficient oxygenation for fish tanks, hydroponic setups and aquaculture. Note that solar panels cannot be used through glass — install the panel outdoors in a high, unobstructed location for best performance. The solar panel is waterproof for outdoor exposure. If you need a greater exhaust volume, the unit can be paired with our nano gas plate. The exhaust cylinder is uniform and fine with high watersoluble oxygen rate. The unit includes a waterproof box with hanging hole; for outdoor installations, either hang the box or position it flatwise upside down. The enclosure is waterproof and dustproof to protect the internal lithium battery. For optimal solar collection, mount the panel at an angle of 40 degrees with the horizontal plane. Around 12 noon the panel should face the sun's rays directly — follow the same installation-angle guidance used for solar water heaters.
