Should I Turn My Aquarium Light Off at Night
Home from work, turn off the lights, the whole person into the dark blue sofa, the color of the sofa and the same seawater, you sit down after feeling like you are gently surrounded by a sea, close your eyes and listen intently, not far away, there is the sound of waves splashing water. Hearing this sound, you squint your eyes and look toward the source of the sound.
You found the answer – it was an aquarium, where fish swam quietly at night, and the aquarium lights were on, glowing with an eerie blue light.
Everything is quiet, you are surrounded by this sea of the sofa, and these fish are surrounded by the aquarium in this simulated sea.
But you suddenly feel worried, if the light is always on, then these fish can get enough rest? Will not be like yourself, into another exhausted sleepy?
The above scenario may be encountered by every fish keeper. For many friends who keep ornamental fish at home, in order to usually facilitate the fish or fish to fill the light will be installed around the tank lights, in general, this light is on during the day, at least when someone at home is on, so when the family has ornamental fish, sleep at night to turn off the lights on the fish tank. You may have the question in mind: should I turn off my fish tank light at night?
First, we need to understand one of the most basic questions:
What is the role of fish tank lights?
1. Promote the growth of fish: In the case of light, the growth and development of fish is fast, and the proper light can make the fish color better and more convenient for viewing.
2. To promote the growth of plants: If there are plants such as green moss and water plants in the fish tank, proper light can promote their growth. Moreover, they can’t carry out photosynthesis without light, with proper light can promote them to release oxygen.
3. Heating: This is mainly for some tropical fish because these fish have high requirements for water temperature, and need to keep the temperature between 20-30 ℃, too cold will affect the appetite, but also may cause illness and death. The light can play a heating effect and can improve the temperature of the environment.
4. Color attraction: Light has an absolute relationship between the growth of the pigmented body of fish and the precipitation and absorption of vitamin D. And because of the light, the vast majority of fish have more pigment cells gathered in the back, while the color of the abdomen is lighter. Many fish look colorful, their color is often related to the light, so the lights in the tank can also induce color for some fish, so they look more beautiful.
5. Increase ornamental effect: The fish can show the best ornamental effect under the proper lighting.
Once we understand the importance of aquarium lighting, we might as well go back to the very first question:
How long should the aquarium lights be on a day? Do they need to be turned off at night?
The length and intensity of the light are related to the placement of the tank and the type of tank. If the tank is placed on the sunny side, it can get enough sunlight during the day, then the tank light can be less and weaker, the light is more used for lighting or ornamental fish tank at night, and vice versa. If it is a grass tank, naturally the light requirement is higher than in a bare tank.
Normally, if the fish tank is placed in the sun, the light is sufficient during the day, then we should turn off the lights on the side of the tank before going to bed at night. If you leave the lights on for a long time, it will affect the health of the fish, and if the light is too long, it will also cause the fish to develop earlier, so some fish will become sexually mature too early and affect the growth rate afterward.
In addition, if the lights are not turned off at night, some microorganisms in the water will be more vigorous reproduction, not only is the algae in the water easy to appear to cause the water to become muddy, and some pathogens will also speed up the reproduction of easy to cause fish health problems, so from this aspect to consider, the lights should also be turned off at night to do.
Of course, if the location of your tank does not have natural light during the day, and there is no daytime supplemental light, this situation is also possible to turn on the light at night (but I personally recommend that it is better to supplement the light during the day), in addition, some fish lovers like to put the tank in the bedroom, after the lights in the tank off, if you want to get up at night to go to the toilet and then turn on the light will scare the fish (especially some large fish more obvious, such as koi fish), this situation can be turned on a low power night light on the side of the tank so that the fish will be less stimulated when you turn on the light.
In this case, you can open a low-powered night light on the side of the tank, so that the fish will be less stimulated when the light is turned on again.
In fact, all living creatures have biological clocks and need to rest as well, and fish are no exception. Our aquarium which controls the water quality, temperature, oxygen, and light is actually in the simulation of nature (rivers, lakes, and seas) and the growth of the fish’s living environment. Therefore, from a biological point of view, the biological clock will make any living creature “sunrise and sunset”, which can promote the normal reproduction of living things.
To sum up, fish is not necessary to turn on the lights all day. Aquarium lights at night it is best to turn off, as for the specific time of the switch you can refer to the sunrise and sunset time.
