Ideal for ponds with fish stock, where the oxygen level drops, especially in summer during high temperatures. The pump is installed outside the water and operates independently of the grid using solar power in direct sunlight. Oxygen can be pumped into the pond through the 2-meter long silicone hose and a bubbling stone. The solar module features a multifunctional ground stake, allowing the module to be set up, inserted into the ground, and adjusted towards the sun using the ball joint.
