hygger Aquarium Air Pump,Adjustable Oxygen Pump，Silent Powerful Aerator Pump 2W/3W/4.5W/6W/ 1/2 Air Outlets Ultra for Up to 100 Gallon Tank

I made a YouTube video reviewing this product because it was so noisy and terrible, and before, I’d heard only praise about how good hygger were, but this is not good at all. You can see exactly how noisy it is from the video.

This air pump is impressively quiet and delivers a steady stream of bubbles, perfect for maintaining oxygen levels in my 20-gallon tank. The adjustable flow is a great feature, allowing me to fine-tune aeration for different setups. It’s compact, easy to install, and doesn’t vibrate much, which helps keep noise down. One tip: use a check valve to prevent backflow. Overall, a solid choice for anyone looking for a reliable, silent air pump.

I bought this after reading the reviews about how quiet it was, and to be fair, it actually was. It’s not quiet anymore. The gentle hum lasted about 2.5 months but now I’m looking for something better.

Controller is not working

The item said it was adjustable. When it arrived it was not, not all the pumps are adjustable. Second the plug was a US plug and 110 volts. I could not use it so cannot comment on its performance. I have other Hygger pumps which are very good. This one i cannot comment on apart from what i said above.
