Degassing apparatus for a fish aquarium or the like

Claim 1

A degasser for fish aquariums and the like comprising a housing having a front wall, a rear wall, a pair of side walls and a bottom wall, a plurality of superimposed baffles in said housing extending from side wall to side wall, the uppermost baffle starting at the front wall and terminating in spaced relation to the rear wall and being inclined downwardly from front to rear, the next lower baffle starting at the rear wall and terminating in spaced relation to the front wall and being inclined downwardly from rear to front, whereby water flowing over said baffles will be thinned out and will flow downwardly in a zigzag path, cascading downwardly over the end of each baffle onto the next lower baffle, first means for feeding water to be reconstituted into the top of said housing, an air chamber located at the bottom of said housing, means for introducing pressurized air into said air chamber, porous means defining the top wall of said air chamber, said porous means permitting pressurized air from said air chamber to pass upwardly therethrough, while at the same time preventing the thinned-out water flowing thereabove to seep downwardly therethrough, whereby air passing upwardly through said porous means and coming into contact with the thinned-out water flowing thereabove will effect the desired gas exchange in said water to reconstitute same, and second means for feeding said reconstituted water from said housing to its desired point of use.
