## Abstract

An aquarium cleaning device includes an isolation zone forming member having opposing first and second sides. First and second liquid passages are formed through the member between the first and second sides, each of the first and second liquid passages having an opening on the second side. A gasket is secured to the isolation zone forming member and forms a loop around the openings of the first and second liquid passages. The gasket is disposed to create sealing contact against an aquarium wall when the isolation zone forming member is held against the aquarium wall. An input tube is fluidically connected to the first liquid passage and an output tube is fluidically connected to the second liquid passage.

## Claims

### Claim 1

An aquarium cleaning device comprising:
an isolation zone forming member having opposing first and second sides, said isolation zone forming member defining a first liquid passage extending therethrough between said first and second sides and terminating at a first opening on said second side, and said isolation zone forming member defining a second liquid passage extending therethrough between said first and said second sides and terminating at a second opening on said second side;
a gasket secured to said isolation zone forming member and extending outwardly from said second side and forming a loop around said first and second openings, said gasket disposed to create a sealing contact against an aquarium wall when said isolation zone forming member is held against the aquarium wall to form an isolation zone between said second side and the aquarium wall;
an input tube fluidically connected to said first liquid passage at said first side;
an output tube fluidically connected to said second liquid passage at said first side;
a first magnet fixedly attached to said isolation zone forming member;
and a second magnet separate of said isolation zone forming member.

### Claim 2 (depends on 1)

The aquarium cleaning device of claim 1, wherein said isolation zone forming member has at least one pair of diagonally opposed corners, and wherein said first opening is disposed at one corner and said second opening is disposed at the other corner so that said first and second openings are disposed diagonally relative to one another.

### Claim 3 (depends on 1)

The aquarium cleaning device of claim 1, further comprising:
a transfer tube;
a liquid pump having an inlet and an outlet; a chemical reservoir; wherein said input tube is connected at one end to said first liquid passage and is connected at the opposite end to said chemical reservoir, wherein said output tube is connected at one end to said second liquid passage and at the opposite end is connected to said inlet of said liquid pump;
and wherein said transfer tube is connected at one end to said outlet of said liquid pump and is connected at the opposite end to said chemical reservoir.

### Claim 4 (depends on 3)

The aquarium cleaning device of claim 3, further comprising:
a quantity of a chemical solution contained by said chemical reservoir.

### Claim 5 (depends on 1)

The aquarium cleaning device of claim 1, further comprising:
first and second chemical reservoirs;
wherein said output tube is connected at one end to said first liquid passage and at the opposite end to said first chemical reservoir; and
wherein said input tube is connected at one end to said second liquid passage and at the opposite end to said second chemical reservoir.

### Claim 6

An aquarium cleaning system comprising:
an isolation zone forming member having opposing first and second sides, said isolation zone forming member defining a first liquid passage extending therethrough between said first and second sides and terminating at a first opening on said second side, and said isolation zone forming member defining a second liquid passage extending therethrough between said first and said second sides and terminating at a second opening on said second side;
a gasket secured to said isolation zone forming member and extending outwardly from said second side and forming a loop around said first and second openings;
said isolation zone forming member being held against an interior surface of an aquarium sidewall with said gasket in sealing contact with the interior surface and forming an isolation zone between said second side of said isolation zone forming member the interior surface of the aquarium sidewall;
a chemical solution circulated through said isolation zone by flowing through said first and second liquid passages;
a first magnet fixedly attached to said isolation zone forming member; and
a second magnet disposed on an exterior surface of the aquarium sidewall and magnetically attracting said first magnet to hold said isolation zone forming member against the interior surface.

### Claim 7 (depends on 6)

The system of claim 6, further comprising:
an input tube fluidically connected to said first liquid passage at said first side;
an output tube fluidically connected to said second liquid passage at said second side;
a transfer tube;
a liquid pump having an inlet and an outlet;
a chemical reservoir;
wherein said input tube is connected at one end to said first liquid passage and is connected at the opposite end to said chemical reservoir, wherein said output tube is connected at one to said second liquid passage and at the opposite end is connected to said inlet of said liquid pump; and
wherein said transfer tube is connected at one end to said outlet of said liquid pump and is connected at the opposite end to said chemical reservoir.

### Claim 8 (depends on 7)

The system of claim 7, wherein said isolation zone forming member has at least one pair of diagonally opposed corners, and wherein said first opening is disposed at one corner and said second opening is disposed at the other corner so that said first and second openings are disposed diagonally relative to one another.

### Claim 9 (depends on 6)

The system of claim 6, further comprising:
first and second chemical reservoirs;
an output tube connected at one end to said first liquid passage at said first side and at the opposite end to said first chemical reservoir; and
an input is connected at one end to said second liquid passage at said first side and at the opposite end to said second chemical reservoir.
