BOLTZ Submersible Aquarium Filter Pump 8 Watt,500 L/H Fluidized Aquarium Filter  (Mechanical Filtration for Salt Water and Fresh Water)

For proper installation, you must ensure this aquarium filter is fully submerged in water, whether placed vertically or horizontally. The top of the filter should always remain below the water surface to maintain efficient filtration and prevent damage to the motor. Furthermore, you must avoid placing this filter above the water level mark, as this can hinder performance and lead to malfunction. If using the air hose for additional oxygenation, make sure it is securely connected and positioned correctly to allow for proper airflow. Whether in a vertical or horizontal layout, this filter must stay completely underwater to ensure optimal water circulation and filtration in your aquarium.

Designed with a noise-free filter, this aquarium pump operates quietly within a range of 0 to 20 decibels, ensuring minimal disturbance in your home or office. For perspective, sounds under 35 decibels are barely perceptible, while those between 40 and 60 decibels are comparable to normal conversation. In contrast, loud noises from 60 to 80 decibels can be intrusive, with anything above 80 decibels resembling the hum of heavy machinery. Oxygenation plays a vital role in maintaining a healthy aquatic environment, and unlike many other filters, this model includes an oxygenation nozzle and air tube. These components enhance oxygen levels in the tank, promoting the well-being of fish and aquatic plants. An integrated regulator makes it easy to adjust the airflow, allowing you to tailor the oxygen supply according to your tank size and specific aquatic needs.
