About This

• 【4-Stage High-Efficiency Filtration System】Three Seconds aquarium filter uses four layers of premium sponges to achieve multi-layer and highly efficient filtration. Fish tank filters can effectively reduce odors and trap impurities, and intercept fish waste and leftover feed, creating a safe and crystal-clear water environment for your aquarium.
• 【Ultra-Quiet Operation(＜30 dB）】Designed with an upgraded motor and low-friction rotor, this fish tank filter runs smoothly and quietly. The shock-absorbing pad helps reduce vibration, making it ideal for bedrooms, offices, living rooms, and other quiet spaces.
• 【Multifunctional Fish Tank Filter】Three water outlets to choose from: 360° rotatable duckbill outlet – won't disturb fish or plants; rain pipe outlet – natural water circulation & oxygen supply; bell-mouth outlet – prevents direct surface impact, significantly reduces noise, and removes floating fish food.
• 【Oil Skimmer Removal Intake Design】The hang on back aquarium filter is equipped with an oil skimmer remover above it, which effectively removes surface oil film and foam, keeping the water clean and transparent. Meanwhile, the bottom of the intake is fitted with an intake strainer that ensures efficient water flow while preventing small fish from being sucked in.
• 【Upgraded Structure】The water pump motor of the Three Seconds hang on back aquarium filter is located on its top cover and minimizing disturbance to your fish during efficient operation. Aquarium filter also enhances the sealing system to ensure safer and more reliable operation.
• 【Easy to use】The aquarium filter adopts a hang-on-back design, allowing it to be placed outside the aquarium and saving space inside. It can be used in various types of fish tanks such as small fish tanks and aquatic plant tanks. Equipped with adjustable mounting clips, it fits aquariums with rims 0.3 to 0.5 inches thick.
