Abstract
An aquarium includes a first chamber arranged to contain a first volume of liquid, a dry chamber that is adjacent the first chamber and defines a second volume, and a removable element at least partially disposed within the dry chamber. The removable element is selectively removable from the dry chamber. The aquarium also includes a filter at least partially disposed within the removable element, and a pump including an intake and an outlet. The intake is arranged to draw a flow of liquid from the first volume of liquid during pump operation. The aquarium also includes a tube having a first end connected to the outlet and a second end movable between a first position in which the flow of liquid passes through the filter and is then discharged into the first volume and a second position in which the flow of liquid flows directly into the first volume.
