Abstract

An aquarium filter arrangement including a filter housing and a filter cartridge positionable within a filter chamber of the filter housing. The filter arrangement includes a hinged cover connected to the filter housing. The hinged cover is designed to collect condensation when the cover is in an open position, and empty the collected condensation into the filter chamber when the cover is closed. The filtering housing also includes guides located above the filter chamber. The filter cartridge can be positioned within the guides during maintenance of the aquarium.

Claims

1. A filter arrangement for use with an aquarium, the filter arrangement comprising:

a) a filter cartridge; and

b) a filter housing defining a filter chamber, the filter housing including;

i) filter chamber guides located in the filter chamber, the filter chamber guides being constructed to position the filter cartridge in a filtering position; and

ii) secondary guides located above the filter chamber, the secondary guides being constructed to position the filter cartridge in a non-filtering position, wherein water contained within the filter cartridge positioned in the non-filtering position drains either into the filter chamber of the housing or into the aquarium.

2. The arrangement of claim 1, wherein the each of the filter chamber guides and the secondary guides define vertical slots configured to retain the filter cartridge in a generally vertical orientation.

3. The arrangement of claim 1, wherein the secondary guides are located adjacent to a spillway defined by the filter housing.

4. The arrangement of claim 3, wherein the secondary guides are configured to position the filter cartridge at a position above the spillway of the filter housing.

5. The arrangement of claim 1, wherein the filter arrangement is configured to externally mount to an aquarium.

6. A method of replacing a filter cartridge in an aquarium filter, the method comprising the steps of:

a) removing a first filter cartridge from a filter chamber defined by the aquarium filter, the aquarium filter being mounted to an aquarium;

b) inserting the first filter cartridge into cartridge retaining structure arranged such that, while being retained, water contained within the first filter cartridge drains into either one of both of the filter chamber and the aquarium;

c) placing a second filter cartridge within the filter chamber; and

d) removing the first filter cartridge from the cartridge retaining structure.

7. The method of claim 6, wherein inserting the first filter cartridge into the cartridge retaining structure includes positioning the filter cartridge generally above a spillway of the aquarium filter.

8. The method of claim 6, wherein inserting the first filter cartridge into the cartridge retaining structure includes inserting the first filter cartridge into secondary guides located adjacent to a spillway of the aquarium filter.

9. The method of claim 8, wherein the secondary guides define vertical slots configured to retain the first filter cartridge in a generally vertical orientation.

10. A method of applying a treatment to an aquarium environment, the method comprising the steps of:

a) providing a filter mounted to an aquarium, the filter including a filter housing and a filter cartridge positioned within a filter chamber of the filter housing;

b) removing the filter cartridge from the filter chamber;

c) inserting the filter cartridge into cartridge retaining structure formed on the filter housing so that the filter cartridge is isolated from a flow of water generated by operation of the filter, the filter cartridge being positioned such that water contained within the filter cartridge drains into either one of both of the filter chamber and the aquarium; and

d) applying the treatment to the aquarium environment.

11. The method of claim 10, wherein the step of inserting the filter cartridge into the cartridge retaining structure includes positioning the filter cartridge such that a gap is formed between the filter cartridge and the filter housing so that water passes through the gap without being filtered by the filter cartridge.

12. The method of claim 10, further including circulating water through the filter housing to facilitate dispersion of the treatment applied to the aquarium environment.

13. A filter arrangement for use with an aquarium, the filter arrangement comprising:

a) a filter housing including;

i) a filter chamber,

ii) first filter cartridge retaining structure located in the filter chamber; and

iii) second filter cartridge retaining structure located above the filter chamber; and

b) a filter cartridge selectively positionable in both a filtering position, in which the first filter cartridge retaining structure retains the filter cartridge, and a non-filtering position, in which the second filter cartridge retaining structure retains the filter cartridge.

14. The arrangement of claim 13, wherein each of the first and second filter cartridge retaining structures define vertical slots configured to retain the filter cartridge in a generally vertical orientation.

15. The arrangement of claim 13, wherein the second filter cartridge retaining structure is located adjacent to a spillway defined by the filter housing, and wherein water contained within the filter cartridges drains either into the filter chamber or the aquarium when the filter cartridge is positioned within the second filter cartridge retaining structure.

16. A method of replacing a filter cartridge in an aquarium filter, the method comprising the steps of:

a) removing a first filter cartridge from a filter chamber defined by the aquarium filter, the aquarium filter being mounted to an aquarium;

b) inserting the first filter cartridge into guides located adjacent to a spillway of the aquarium filter, the guides being arranged such that water contained within the first filter cartridge drains into either the filter chamber or the aquarium;

c) placing a second filter cartridge within the filter chamber; and

d) removing the first filter cartridge from the cartridge retaining structure.

17. The method of claim 16, wherein the guides define vertical slots configured to retain the first filter cartridge in a generally vertical orientation.

18. A method of applying a treatment to an aquarium environment, the method comprising the steps of:

a) providing a filter mounted to an aquarium, the filter including a filter housing and a filter cartridge positioned within a filter chamber of the filter housing;

b) removing the filter cartridge from the filter chamber;

c) inserting the filter cartridge into cartridge retaining structure formed on the filter housing, and positioning the filter cartridge such that a gap is formed between the filter cartridge and the filter housing, wherein water passes through the gap without being filtered, the filter cartridge thereby being isolated from the flow of water generated by operation of the filter; and

d) applying the treatment to the aquarium environment.
