The AMOSIJOY external aquarium filter is recommended for 55-gallon freshwater fish tanks, turtle tanks, and aquariums. It runs at 225GPH (850L/H) and has a wattage of 9W, with dimensions of 14.2"×10"×8". The filter features a lift-draw style vent valve and a flow regulating handle. After powering up, users can drain the air out of the pump and supply water by lifting the vent valve, allowing the filter to enter proper working condition without the need for additional water addition. The water flow can be adjusted from maximum to minimum, or even to zero, by controlling the top water flow regulating handle.

The filter operates in an ultra-quiet manner, thanks to its built-in motor in the lid. The low wattage and high flow, without air inside the filter, generate minimal noise, with a sound level of ≤ 30dB, ensuring that the family's daily life is not affected while providing effective water purification.

The Amosijoy 225GPH external canister filter features two layers of media baskets, allowing users to place different types of filter materials to purify the water and maintain a healthy living environment for aquatic life. Users can add additional filter media as needed. The filter is also equipped with complementary bio balls and ceramic bio balls, which help to speed up the decomposition of fish feces, reducing the need for frequent changes of the cotton filter.

Overall, the AMOSIJOY external aquarium filter is a versatile and efficient solution for maintaining the water quality in 55-gallon freshwater fish tanks, turtle tanks, and aquariums, while ensuring a quiet and hassle-free user experience.
