Review on Aqueon Circulation Pump: Enhancing Water Flow for Optimum Aquatic Health by Nikita Sweet

As this is a great wave generator this is the best I have ever had. The suction cup is a great design and I don't hear any vibration from it. BUT the holes are huge. So big, in fact, that I lost both measles and a 6 inch rosy shark on Death's Blades. I sacrificed some mesh and covered up the holes, but having such a large gap in the front is sloppy and a fatal design flaw in my opinion. 3 stars. If you buy one make sure you install your own safety screen so you don't lose your fish like I did.
