Multiple functions: ① Oxygenation, providing sufficient bubbles and gentle water flow. ② Filtration, the dense biochemical cotton on the upper layer can effectively absorb impurities, feces and debris, while the concave structure increases the filtration surface, which helps to improve filtration efficiency. ③ Cultivation, the bottom uses bio-ceramic ball media, which helps to cultivate more beneficial substances needed by the water tank
Design concept: This single sponge filter can be fully utilized, not bulky, lightweight and convenient. It adopts an electric design and does not need to be used with an air pump. You only need to connect the USB plug to any adapter (5V, 1A adapter is not included) to use it, avoiding the instability of air pressure and water flow caused by an inappropriate air pump, affecting the filtration effect
Cleaning and replacement: All parts included in our aquarium filter are detachable and can be easily assembled and disassembled. Including 50g ceramic balls and two reusable sponges, it is recommended to replace or wash the sponge every 2-4 weeks, or use tank water to clean the filter assembly whenever you see a decrease in bubbles to ensure that the filter works properly
2 water outlets: Fish tank filter is equipped with a rain shower pipe and a duckbill outlet, and there are 2 ways to discharge water. You can connect different accessories to choose different modes. The shower waterfall design can effectively increase the dissolved oxygen level in the aquarium; while the aerated water outlet design can enhance water circulation and achieve a stronger filtering effect. The water flow rate and water flow direction can be adjusted as needed
Usage: In order to achieve hands-free operation, the sponge filter can be sucked or hung inside the water tank, equipped with an adjustable hanging clip and 2 suction cups, providing flexible settings. You can choose the appropriate usage method according to your needs. In addition, the outlet height can be adjusted by the telescopic tube and sliding clamp to meet the needs of different heights of the water tank and show different usage effects
