Review on 🐠 Ultra-Quiet AsiaPPump Aquarium Air Pump: Super Energy Efficient 1-1.5W Aerator for 24-40 Gallon Fish Tanks with Air Stone and Oxygen Tube by Erin Buck

I use it to aerate my 30 liter tank. It's been up and running for a year now and works fine. The bubbles are still coming out of the included stone and they keep the water moving in my aquarium very well. My tank is on the edge of my living room and I only hear the pump at night when all else is quiet. My Aqueon filter, which also runs on this tank, is much louder. The only thing I added is a backflow restrictor which is not included in the kit. quality product.
