Review on Aquamaxx WS-1 In-Sump Protein Skimmer: Efficient Filtration Solution for Crystal Clear Aquariums by Stacy Edwards

Difficult to set up. A significant amount of water accumulates at the 4 corners of the collection tank. The sealing ring does not seal the gap due to the large difference in the radii of the corners of the sump and the outer wall of the housing. It's also almost impossible to adjust the airflow. Plan to save and make changes to ensure a better seal, but certainly not as expected! If you don't mind water spurting out of the top of the device, this might not be a problem. for your application.
