Hygger oxygen filter transforms an aquarium into a true mini-ecosystem with crystal-clear bubbles. Unlike conventional aerators, nanotechnology increases the contact area between water and oxygen, making saturation more efficient. The bubble size is adjustable, allowing you to tailor the airflow to the needs of fish, shrimp, and plants. It operates ultra-quietly, without vibrations or unnecessary noise. Perfect not only for aquariums but also for hydroponic systems, ensuring an optimal oxygen level for plants
