I love the fact that I can adjust as well and it is super quiet and I can’t hear it unless I have my ear right up to it. The aqua top pump you could hear across the room and you could hear it definitely at night.
Was completely surprised on how much air this pump put out, and super quiet! the air pump is awesome.
This is a great pump! It’s super quiet and the control feature was a must for us with our little Betta. I love the twin outlet, as well. Currently, I have your basic filter system set up, but I’m going to add some bottom feeders
