Aquarium system with controlable light and methods

1. A method of lighting an aquarium system comprising:

(a) projecting light source that extends along a length of an aquarium tank arrangement having a plurality of tanks positioned side-by-side; the light projecting in each of the plurality of tanks and having at least two different colors; and

(b) actuating a cycle of the projecting light of at least two different colors along the length of the aquarium tank arrangement in,

(i) predetermined distance increments; and

(ii) predetermined time increments.

2. The method of claim 1 wherein the plurality of tanks includes at least three tanks positioned side-by-side; and the step of actuating includes projecting a first light color in the first and second of the tanks, while projecting a second light color into the other tanks.

3. The method of 1 wherein the at least two different colors of the light are white light and blue light.

4. The method of claim 1 wherein the step of projecting light includes using the light source with a controllable output of colored light projecting into the aquarium tank arrangement and positioned to project colored light in each of the tanks; the light source including a plurality of light emitting diodes within a fixture along the length of the tank arrangement.

5. The method of claim 4 further including the fixture having a connector along a length of the tank arrangement; and a programmable control box connected between the fixture and the connector.

6. The method of claim 5 further including programming the cycle of the projecting light using an application executable on a mobile device.

7. The method of claim 5 wherein the control box has a manually operable switch and the method further includes using the switch to program the cycle of the projecting light.

8. The method of claim 1 wherein the step of projecting light into the aquarium tank arrangement includes projecting the light into an array of individual tanks positioned in rows and columns; and using a plurality of the light sources, at least one light source positioned for each row to project colored light in all of the individual tanks for the respective row.

9. The method of claim 8 wherein the step of actuating the cycle of the projecting light includes actuating a cycle of projecting colors along predetermined distance increments and time increments along the length of each row, and including emitting a first light color into one or more of the individual tanks in the respective row and, simultaneously, a second light color into one or more of the individual tanks in the respective row.

10. The method of claim 9 wherein the light source for each row is in a fixture mounted above each individual row.
