Feature: 1. Oxygenated Pump: This fish tank cleaner comes with a pump attached to the air valve. With 2 air stones and 1 silicone hose included in this kit, you can simultaneously supply fresh oxygen to your aquarium tanks. Fish in the tank get to breathe fresh, oxygenated air. 2. High Efficiency: The pump is made of ABS, which absorbs outdoor air and sends it into the tank through the outlet. This allows the aquarium to receive oxygenated water that maintains healthy marine life. It is ideal for aquaculture oxygenation, high-quality aquarium decoration and pipe decoration, helping to create a healthy environment for your fish. 3. Less Power: Unlike a regular air pump, this aquarium pump has 2 complete sets, so you can use two air stones separately in different tanks at the same time, but you save on your electricity bill. The outlet hole is large enough to allow constant airflow. 4. Practical Low Noise Design: Silicone hoses and air stones transport oxygen and release it into the water in the form of bubbles. In this way, unwanted carbon dioxide is removed from the aquarium without any hassle. 5. Wide Compatibility: The main purpose of the aerator is to add fresh oxygen and water movement to the tank. However, this oxygen pump allows a maximum flow of 1.8 L/min for all water aquariums. The steel part uses the latest shock-resistant material, long service life.
