Light is critical if there are live plants in the tank, and for this it must be adequate in intensity and spectrum. If there are no live plants, then the light is solely there to illuminate the aquarium and the intensity and spectrum are up to you, though one should never have more light than necessary for the health of the fish.Hey Bryon, I just came across this articale and found it very interesting since i just moved my African Cichlids to a new tank thus a new light also. Which im using a home depot light fixture and just regular flourcent tubes. wht would you recommend for light on a 125g tank? Where i can dupilcate sunset sunrise?
Sunset/sunrise can only be achieved using true daylight, as through the room windows. Once the room is lit, then the tank light can come on. And the tank light must go off before the room loses daylight. With lighting over the tank, you can have more than one tube and have them on different timers to come close to a similar effect.
