How much light do I need?

[Anthony8858]

I have a 36 gallon bow front.
Fish ONLY and Live rock.
The tank is in a shady room, without any natural sunlight.

Is there a "formula" for establishing a proper amount of light?

You really only need the light necessary to see the fish if you are not keeping animals that require light. Coraline Algae does well in moderate lighting.

I would say go for a 36 watt PC setup. Coralife makes a good one that i use.
