VILLNO 3W Mini Fish Tank Filter, 180LPH Quiet Aquarium Internal Filter 3-IN-1 Submersible Pump for 3-25L Betta/Fry/Shrimp Tanks

This palm-sized mini filter (approximately 11 cm in total length) is a small aquarium filter that operates with a 3W power head. It is perfect for small or mini aquariums ranging from 3L to 25L, allowing efficient water quality management even in limited spaces. Gentle Water Flow: This fish tank filter features a mild water flow and a fine intake, significantly reduces the risk of shrimp and fry being sucked in, making it suitable for delicate aquatic creatures such as shrimp tanks, breeding tanks, betta tanks and other small fish tanks. Quiet Operation: With excellent quiet performance, this filter produces almost no noticeable operating noise, making it ideal for quiet environments like bedrooms or offices. It allows you to enjoy the presence of an aquarium in peace. Easy to Maintain: Clean the filter sponge approximately once every 10 days and replace the biological filter media every six months to a year to maintain a clean water environment. Multi-Functions: This compact filter integrates three functions—filtration, water circulation, and aeration—into a single unit. It is an ideal mini aquarium filter pump for nano tanks, such as those housing small fish like bettas, to maintain clear water quality. This fish filter is equipped with an intelligent temperature control device. When the water temperature is too high or the filter is running with low water level, if it detects that the internal motor temperature is too high, it will automatically stop working; once the temperature drops, it will automatically restart, making it safer and more reassuring to use.
