- Solar powered operation: The 1.4 W Sun Fountain runs on sunlight, requiring no electricity or battery. When sunlight is sufficient, it starts automatically and can spray water to a height of 40-60 cm within about 3 seconds, helping attract birds to your backyard. - Six nozzle options for adjustable height: Includes 6 different nipples to easily change the water height. The connected pipes help prevent the fountain from moving randomly, so you can enjoy the soothing drip and flow of water. - Water protection and durability: When water runs low, the fountain stops working. The filtration box prevents dirt, dust and leaves from entering to extend the life of the unit. The Pet Laminated Solar Panel ensures the Sun Fountain can operate in less-than-ideal environments. - Size, compatibility, and performance: The fountain has a diameter of 5.1 inches and requires a minimum water depth of 1.2 inches. Suitable for bird baths, fish tanks, small ponds, pools, and gardens, making it ideal for circulating water and enhancing oxygenation. - Practical use scenarios: - Backyard bird bath: Attract birds and improve water aeration with a gentle spray. - Small aquatic setups: Use in fish tanks or small ponds to promote circulation and oxygen exchange. - Garden and pool enhancement: Place in a pond, pool, or decorative water feature to bring life and movement to the water.
