Review on AquaTop AP 100 Aquarium Air Pump by Megan Hartman

I've been using this air pump with two air stones in a 35 gallon aquarium for about a week. So far I am very satisfied because it is very quiet. I thought the air adjustment would be very variable, but this is my first air pump with an adjustment, so I can't compare it to others. I would buy one of these pumps again at any time. The attached picture shows how much air comes out of the air stones at low pumping level.
