There is a siphon conduit having a siphon conduit inlet at a first elevation within the siphon chamber, a siphon conduit outlet at a second elevation below the first elevation, and a crest at a third elevation above the first and second elevations. The siphon conduit empties into a catch basin, where the processed water is transported back to the aquarium.Type: GrantFiled: May 14, 2009Date of Patent: October 5, 2010Inventor: Dean Smith

Patent number: 7682503Abstract: An improved and more efficient design for an air driven algae filtration system is achieved because there are no moving parts other than an air pump, and the air is used twice. After using air to circulate water through a filtration unit, the air, still under pressure, is separated from the water. The air is then plumbed to other apparatuses or used for cooling. This allows the filter to be utilized using less electricity. The water is de-gassed before reaching the algae filter. Therefore, no splash guard is necessary to prevent water from splashing the lights. With no splash guard, lower wattage lights can be used to illuminate the algae. This also increases the efficiency of this system. This filter also lends itself to maintaining a reef aquarium.Type: GrantFiled: September 10, 2008Date of Patent: March 23, 2010Inventor: Joe Norris

Patent number: 7670484Abstract: A filter cartridge including a filtering body having first and second porous filter walls. The second porous filter wall having a density that is different than the first porous filter wall. The density of the second porous filter wall being defined by interstitial spaces. The filter cartridge further including discrete chemically filtering particles that are captured within the interstitial spaces of the second porous filter wall when the filtering body is in a vertical filtering orientation.Type: GrantFiled: August 15, 2007Date of Patent: March 2, 2010Assignee: Tetra Holding (US), Inc.Inventors: Daniel A. Newman, Donald Barry Huehn

Patent number: 7631616Abstract: The aquarium creates a smooth circulation of water flowing through mechanical, biological, and chemical filtration mechanisms. The three filtration mechanisms are housed in a vertical first compartment and a vertical second compartment, both along a back side of the aquarium body, and a lateral third compartment along a bottom side of the body, respectively. A water pump draws water from the third compartment into the second compartment. After a first filtration processes, the water is poured back into the body. Due to the suction of the water pump, water flows from the body into the second compartment to undergo a second filtration process and then enters the third compartment, where a third filtration process is conducted. The water is finally drawn into the second compartment to complete the circulation.Type: GrantFiled: November 1, 2007Date of Patent: December 15, 2009Assignee: Hi-Q Bio-Tech International Ltd.Inventor: Chin-Hui Hsieh
