hygger 3.5W Quietest Aquarium Air Pump+1.4in Mini Aquarium Air Stone

Quiet Aquarium fish tank air pump + Quiet Aquarium fish tank nano air stone

• 6-step Quiet Air Pump: Thickened ABS plastic, sealing machine noise; Stainless steel cover, locked motor sound; Bearing less motor, works through magnetic bearings; Internal support feet, the motor does not touch the cover, reduce noise; 8 bottom rubber feet, reduce vibration; Noise reduction motor.The water cup on on top of pump will not vibrate violently and flow out
• Adjustable Air Pump: With adjustment control knob, the air flow can be adjusted according to your own preferences, up to 80GPH. The air is used to vibrate the air bubbles to increase the area of the water contact with the air, so that the water can dissolve the oxygen, thereby increasing the oxygen content in the water
• Double Air Outlet Pump: The bubbles are even,natural and stable. Can be connected to nano air stone, biochemical sponge filter, landscaping windmill rockery, aquarium air shell and other aerobic landscaping equipment. Suitable up to 120gallon fish tanks (cannot exceed 3.9 feet water depth)
• Fine bubble: Oxygen stone refines the air output from the air pump into a particle bubble, which is smaller and denser, like the atomization effect, and the bubble size can be adjusted, and the different oxygenation amount can satisfy different use requirements
• Quality Nanomaterials: The nano-stone is sintered at high temperature. The material is sturdy and durable. It can be used for a long time and has better dissolved oxygen effect. When the bubble burst into the water, the sound is super quiet.Compared with ordinary bubble stone, the nano bubble stone emits more bubbles, and the gas and the water surface are more widely contacted, which makes the dissolved oxygen amount larger
