Multifunctional Aquarium Filter: Our aquarium filter has four main functions: pumping, oxygenation, filtration, and circulation. The aquarium pump can be used for both fresh and saltwater. It removes impurities in the aquarium, creating a healthier water environment for living organisms. Adjustable Water Flow: The maximum flow of this internal aquarium filter can reach 300L/h, which is very suitable for 60L aquariums. The unique design allows you to regulate the water flow through the water inlet pipe on the side of the internal aquarium filter to supply oxygen to the aquarium. Two Ways to Use: There are two ways to use the aquarium pump. You can increase oxygen through the water inlet pipe and nozzle, or use the rain pipe connection to improve the filtering effect and filter the water more completely. In shallow water, the filter can be placed on its side underwater for use in turtle tanks. Easy to Install and Clean: There are multiple rubber suction cups on the outside of the aquarium filter, so the filter can be easily attached to the aquarium. The suction cup has strong suction, is safe and stable, and does not slip easily. At the same time, the built-in filter floss can be easily replaced by simply removing the cover. IMPORTANT NOTE: Rain mode and oxygen mode cannot be used simultaneously. When using rain mode, adjust the water volume correctly to avoid excessive water flow and affecting the life of the fish.
