Aquarium with water change system
A water change system includes an elongate tube and a spout configured to be coupled to the elongate tube. The spout includes a first opening and a second opening spaced from the first opening. The spout is rotatable between a first position to permit water to enter the second opening and pass out of the first opening, and a second position to inhibit water from entering the second opening.
1. A water change system for a tank having a liquid disposed in an interior, the water change system comprising:
an elongate tube disposed at least partially within the interior and including an open first tube end disposed in a lower half of the tank;
a spout coupled to a second tube end of the elongate tube, the second tube end opposite the first tube end and disposed in an upper half of the tank, the spout including a cylindrical wall, an end wall, a first opening and a second opening spaced from the first opening, the second opening formed in a portion of the cylindrical wall such that the entire aperture is formed on one side of a central axis of the spout, wherein the spout is rotatable between a first position wherein the second opening is disposed below a desired waterline to permit water to enter the second opening and pass out of the first opening, and a second position wherein the second opening is above the desired waterline to inhibit water from entering the second opening.
2. The water change system of claim 1 , wherein the spout includes a first end and a second end, wherein the first opening is disposed at the first end and the second opening is disposed at the second end.
3. The water change system of claim 2 ; wherein the second end includes a wall, wherein an axis extends through the first opening and through the wall, and wherein the second opening is disposed adjacent the wall.
4. The water change system of claim 3 , wherein the axis is configured to extend perpendicular to a gravity vector.
5. The water change system of claim 2 , wherein the spout includes a protruding finger grip at the first end.
6. The water change system of claim 1 , wherein the first opening is a circular opening, and wherein the second opening is a non-circular opening.
7. The water change system of claim 1 , wherein the spout has a generally cylindrical shape, and wherein the second opening is formed by a cut-out.
8. The water change system of claim 1 , wherein the second opening is defined by a first, arcuate surface and three additional surfaces that each extend in a plane that is perpendicular to a plane that contains the first surface.
9. The water change system of claim 1 , wherein the elongate tube includes a bottom end having at least one aperture configured to receive dirty water.
10. The water change system of claim 1 , wherein the elongate tube includes an upper L-shaped hollow end configured to receive the spout.
11. An aquarium comprising:
a bottom;
at least one side wall extending from the bottom, the bottom and side wall defining an interior space;
an elongate tube disposed at least partially within the interior space and including a first tube end disposed within a lower portion of the space and a second tube end disposed in an upper portion of the space; and
a spout coupled to the second tube end and passing through the side wall, the spout including a cylindrical surface, a first opening and a second opening spaced from the first opening, the second opening formed in a portion of the cylindrical wall such that the entire aperture is formed on one side of a central axis of the spout, wherein the spout is rotatable between a first position wherein the second opening is disposed below a desired waterline to permit water to enter the second opening and pass out of the first opening, and a second position wherein the second opening is above the desired waterline to inhibit water from entering the second opening.
12. The aquarium of claim 11 , wherein the elongate tube extends from a lower portion of the interior space adjacent to the bottom, to an upper portion of the interior space.
13. The aquarium of claim 11 , further comprising a cover coupled to the at least one side wall.
14. The aquarium of claim 13 , wherein the cover includes at least one light-emitting diode.
15. The aquarium of claim 11 , wherein the at least one side wall includes four side walls.
16. The aquarium of claim 11 , wherein the elongate tube extends generally alongside the at least one side wall.
17. The aquarium of claim 11 , wherein the spout protrudes out of the interior space.
18. The spout of claim 11 , wherein the first opening is a circular opening and the second opening is a non-circular opening.
