More Details
Main highlights
- Versatile Application: This aquarium filter is primarily designed to remove remain and waste from fish and turtles in aquariums, keeping the water clear, oxygenated. It is suitable for fish growth and can be used in various settings, including home aquariums, aquarium exhibition tanks, and flower and bird market tanks.

The dual quick-release head design makes cleaning and maintenance a breeze, and the inlet has an oil film removal feature to ensure ample oxygen in the fish tank.
- Silent Operation: Equipped with an internal pure copper brushless motor, the filter operates extremely quietly. There is no air inside the filter, ensuring low power consumption and high flow rate without any noise. The sound level is less than 50 decibels, so your home life won't be disturbed, while still achieving effective water purification.
- High Sealing: The quick-release joint design enhances the sealing of the ports, greatly improving the convenience of disassembly and cleaning, and optimizing the leak-proof design. The thickened and tightened silicone ring design reinforces leak prevention. The rotor structure has been optimized to extend its lifespan, with both ends of the rotor becoming an integrated unit.
- Efficient Filtration: The built-in pump has a maximum flow rate of 528GPH(2000 L/H) with a power of 20W, recommended for use in 200-gallon freshwater aquariums, turtle tanks, and fish tanks. The water flows through the media layers to filter water and ensure a clean aquatic condition. Each layer has a sponge to hold it in place, and it comes with ceramic rings and bio-balls.
