The pump uses the latest power system and is very compact, but the oxygen output is increased. A variety of specifications and accessories can be selected according to needs.

Key Features
Smaller & Stronger Oxygen Pump
hygger HG037 fish tank oxygen pump is smaller but stronger in power. It doesn’t take up space in aquariums. For family fish tanks, you can use one 037 air oxygen pump to supply sufficient oxygen for pet fish. It is very suitable for use in both large and small freshwater and saltwater fish tanks.
Adjust Oxygen Output
The oxygen output can be adjusted manually. You can adjust the appropriate oxygen output by yourself according to the number and the characteristics of the fish, which is more beneficial to the tank creatures.
Quiet oxygen pump
Although it has great power, it has a small noise.
