Review on 🌀 Advanced Deep Blue Professional ADB61037 Hurricane Category 5 AC/DC Air Pump with Battery Operation by Adam Smith

I am shocked that someone has written a negative review about this product. I bought two about a year ago and am now buying two more to put away as a backup. I have one on my 180 gallon tank and another on my 150 gallon tank. Each delivers two strips of air and releases a large stream of bubbles. Also, I do twenty percent water changes in each tank every Sunday morning, which means I shut down each tank for about an hour. The airflow is never interrupted. I still haven't tried the D cell battery option as the factory installed batteries still work. Of all the air pumps I've tried over the years, this one stands out in its class for the money.
