A fluid surge assembly for treating aquarium water and other fluids includes a treatment unit for receiving fluid, treating the fluid and depositing the fluid along a flow path to a body of fluid and a weir assembly disposed in the flow path between the treatment unit and the body of fluid. The weir assembly includes a lower weir blocking a portion of the flow path and an upper weir. The lower edge of the upper weir is offset from the crest of the lower weir to define a first fountain path. The crest of the upper weir defines a portion of a second fountain path. The second fountain path intersects the first fountain path to increase the velocity and distance traveled of the fluid. The invention also includes aquarium systems employing the fluid surge assembly. In some embodiments, the aquarium systems provide an opaque decorative member to block the treatment unit from view. In some embodiments, the decorative member is live rock. In preferred embodiments, a top portion of the decorative member is disposed below the first and second fountain paths to create the image that waves are crashing over rocks. In a particular embodiment, the aquarium tanks are constructed to surround the treatment unit and hide it from view from all sides of the tank.
