Abstract: An internal marine aquarium filter that provides protein skimming, biological, mechanical and chemical filtration is disclosed. The filter creates direct adjustable current for the aquarium independent of the activities of filtration and uses a pump. The filter includes an outer casing with dedicated areas for biological, mechanical and chemical filtration, a selectively removable protein skimmer with collection cup and optional lid, a selectively removable plumbing assembly connected to the pump. An optional surface debris filtering function is also disclosed.

Abstract: The Aquarium Backup Life Support System provides a method of delivering air and circulation to an aquatic environment that does not rely on pumps, batteries or chemicals. The system utilizes a source of compressed air that is delivered into the aquarium or container transporting live aquatic animals in the form of automatic bursts of air that deliver oxygen, circulate the water and provide gas exchange to aid in the elimination of carbon dioxide. The duration, volume and timing of the automatic bursts of air can be preset or controlled. This automatic delivery of air enables an interchangeable tank of compressed air to provide long-lasting life support to an aquatic environment. The automatic delivery of the bursts of air may be initiated by a solenoid valve that senses a loss of power to the aquarium system.

Abstract: The Interlocking Aquarium Support System with Multifunctional Decorative Facade allows for the façade of the aquarium stand to be changed without dismantling the aquarium system. The aquarium is supported end to end at center, front to back and under all sides by vertical supports, a base and top while still providing ample room for storage. The interlocking of the elements prevents movement of the aquarium under load. A foam layer between the aquarium and stand compensate for unevenness and vibration. The stand assembles and disassembles without tools or fasteners and stacks flat when not in use. The removable multifunctional decorative facade is constructed of various materials that provide decor and functionality such as storage, doors, folding sides, graphics, print, and perform functions that enable one to play games of skill or chance inside the aquarium where coin is exchanged for play and the controls are on the façade.
