Aquarium light will illuminate fish colors, regulate fish sleeping habit and make it easier to spot problems. Turning lights off at night will definitely help tank inhabitant mimic pet’s natural environment. Before determining how much light to provide, requirements for individual fish species should be checked. Home aquarium fish species will stop eating, become lethargic, or ill without sufficient lighting. Most common problem caused by excessive light is algae overgrowth and it will grow much quickly in the absence of light. Many fish species are stressed by excessive light and may begin fighting with another fish species. Aquarium light timers are the easiest and most effective method to regulate fish’s day or night cycle.
If an aquarist does not want to use light timers, they can set an alarm and turn the light on or off at the same time. Consistent light cycles in an aquarium tank replicating daylight and nighttime mimic natural environments. Ceramic bulbs are often found as an excellent alternative to bright heat lights and they produce only heat without producing light. Most aquarium fish requires twelve hours of light in a typical day and goldfish will lose color without adequate light. As algae growth will make aquarium tank look dirty, it is necessary to root out algae growth by providing sufficient light.
