DONGKER Hang On Back Aquarium Filter, 3W/5W Multi-Stage Filtration | Automatic Height Adjustment Silent Waterfall Fish Tank Filter with Oil Skimmer Oxygen Increasing for Fish Tank
Multi-Stage Filtration： The multi-layer biochemical filter panel employs a combination of physical and biochemical filtration through porous sponge, activated granules, and filter grids to break down and remove debris and nitrate to keep water crystal clear. Replaceable filter pads enable easy quick maintenance.
Aeration And Water Circulation: The waterfall-style outlet mimics natural water volume, increasing oxygen levels in the water while circulating and filtering it to provide fish with ample oxygen.
Automatically Adjust Height: The automatically floating oil film removal basket adjusts its height based on the aquarium’s water level to remove oil films from the water’s surface, keeping it clean and clear.
Quiet Working, USB-Powered: Quiet working as low as 25dB with shock-absorbing bracket to reduce vibration. DC 5V low power consumption via USB plug, suitable for power banks, phone adapters and USB sockets.
Adjustable Water Volume: The volume control valve allows for easy adjustment of water volume. Wall-mounted installation saves space. Suitable for both freshwater and saltwater aquariums. Before first use, be sure to fill the filter cartridge’s water reservoir with water.
