Abstract: An aquarium air-manifold having modular-construction provision, serving to beautify the typical aquarium by virtually eliminating the usual entanglement of multiple air/feed-lines visibly extending down the inside wall of the aquarium. Preferably molded of transparent-plastic to a squared-tubular cross-section, the manifold can be formed into a grid like format, and several modules may be plugged together to cover as large an area on the floor of the aquarium as may be desired. The air-manifold preferably draws upon only a single air/input-line, while serving a plurality of provisional outlets. Each outlet may either adapted with a plug or an outlet-fitting, thereby enabling the aquarium designer to create any convenient arrangement of outlets as may be desired for the particular aquadic-environment.

Abstract: A urinal having a pair of sidewalls which are integrally connected at rear edges thereof to form a V-shaped configuration. The apex of the V-shaped configuration is offset from a plane perpendicular to a plane defined by the front edges of the sidewalls. Both a wall mounted and full height urinal is disclosed.
