Aquarium Filter Internal Quiet 4W 450L/H Black Description

【Biochemical Filtration】This aquarium filter has 1 box of biochemical cotton inside, which collects and filters waste in the water, creates waves and circulating flow. It helps to cultivate beneficial bacteria and create a healthy water environment for your fish and turtles. The biochemical cotton is washable and reusable. 【Increase Oxygen】The air intake of the aquarium filter increases the oxygen content of the filtered water, which makes the fish more active. In addition, a good oxygen supply helps to cultivate beneficial bacteria such as nitrifying bacteria. You can adjust the oxygen supply by turning the air intake valve. PS: The air intake valve should be placed outside the aquarium and be in contact with air. 【Ultra Quiet】The premium pump motor is silent during operation. It is only 35 dB, almost like a whisper or the sound of a quiet library. We recommend that you turn off the spin button and stop the air intake process at night, so that the filter pump will be quieter. This will not affect the function of the filtration. 【Easy to clean】It is very convenient to take out the biochemical cotton and wash it, or you can replace it with another filter medium.
