Ultra-thin Design: The ultra-thin aquarium filter adopts a compact design, allowing it to easily adapt to various aquarium sizes and spatial layouts without occupying excessive space while maintaining an aesthetic appearance.
Quiet operation: This type of filter adopts advanced quiet technology, making the noise during operation extremely low and not causing interference to the indoor environment, providing a peaceful living environment for fish & shrimp.
Oxygen enhancement function: The water flows back into the fish tank in a waterfall form from the outlet, increasing the oxygen content in the water. Adequate oxygen can promote the healthy growth and reproduction of fish and shrimp.
Adjustable flow rate: The appropriate water flow rate can provide a comfortable living environment for fish and other aquatic organisms. For example, some fish prefer to swim in areas with fast water flow, while some plants require slower water flow to maintain growth.
