Notes and suggestions: On one hand, the fountain is suitable for both above-ground and in-ground pools. On the other hand, if you want a powerful spray, it depends on your pool pump! The spray distance of a 0.75HP sand pump can reach up to 10 meters, while the spray distance of a 0.1HP standard filter pump can reach about 4 meters. It is recommended that you use a filter pump of at least 0.2hp and above. Versatile design: The unique square opening at the bottom of the center tube allows you to customize the water flow and atmosphere by adjusting the opening size. The fountain enhances your pool experience by lowering the water temperature by 10-20°F and producing a constant water mist, creating a soothing, relaxing atmosphere to help relieve stress. Reliable Material：Made of high-quality ABS plastic, this fountain is durable and not easy to yellow, break, or corrode. It enhances your pool experience by improving water circulation and producing soothing sounds. Suitable for swimming pools and garden ponds, it adds decorative appeal and improves the atmosphere, especially in summer. Controllable waterfall direction and height: Create the perfect pool atmosphere with our pool waterfall fountain. 360° adjustable height and direction of the horizontal and vertical tubes allow for cross-water or parallel jet angles to accommodate a variety of pool sizes and shapes. Use the side valves on the bottom to adjust water pressure and height, and orient the nozzle toward the pool when changing direction to ensure optimal performance. Universal Compatibility – Effortless Setup for Any Pool Designed as above ground pool accessories and pool accessories for inground pools, our fountain connects seamlessly to 1.5" inground jets or 1.25"/1.5" above-ground fittings. Works flawlessly with Intex, Bestway, Coleman, and more – no adapters or tools needed! Just screw it onto your return jet and let the magic begin in seconds. 1
