Is it possible to turn off the light in the aquarium

Turn off the lights in the aquarium or not?

It is imperative to turn off the light. For fish, in fact, the brightness of the light is not so significant, but for fish the light should burn approximately in the interval from 10 to 14 hours. But light plays a special role in plant life. I cannot imagine your aquarium with such peaceful fish without plants. Depending on their photophilousness, brightness is set. When it is day, plants release oxygen into the water, and when it is night, carbon dioxide. Both are important. The compressor with a filter can be turned off only if your aquarium is densely populated with vegetation and is not very populated with fish (for each guppy, zebrafish. 2 liters of water, swordtail, molly, catfish. 3 liters). as well as a preferable temperature of about 24 degrees (at a higher temperature, the concentration of oxygen in the water decreases) and you must be sure that you do not overfeed the fish. If your aquarium is overcrowded, you cannot turn off the aeration. Under more favorable conditions, you can try to leave only the filter at night, if it is with aeration. Check if the fish will swallow air from the surface of the water in bulk, then there is not enough oxygen. It is desirable that one aeration device should work continuously! For example, he prevented me from sleeping, now I’m used to it, and these appliances consume a tiny bit of electricity. And oxygen also oxidizes substances harmful to fish that enter the water along with food, droppings and urine of fish. Good luck.

The aquarium should mimic the natural habitat of fish.
– The fish are tropical, so they don’t need temperature surges. leave the heater. If your room is not 30.
– we remove the lighting. It’s night after all. Ideally imitate dawn. sunset. That is, the lighting turns on and off gradually. At home, it is enough to turn off the light in the aqua and leave it in the room for a while.
– the compressor (aerator) can be turned off. if it interferes with sleep. Provided that there are not too many fish for the volume of water. Fish breathe at night too.

In order not to think about turning on and off, it is convenient to use a timer. Like that. Turns off and turns on the light (or other electrical appliance) itself at a given time. Very comfortably.

Should the aquarium lights be turned off at night? and whether it happens that the aquarium can be oversaturated with oxygen?

the light must be turned off at night, in the summer the light mode is about 12×12 hours, in the winter you can have 8-10 hours with the light, then turn it off, the fish need rest, and the plants. dark period for recycling the carbon accumulated during the day. there cannot be an excess of oxygen in the aquarium, the excess is removed on its own, this is the drawback. easily, normal people do not turn off aeration at night, because at night oxygen consumption increases (and fish consume plants, plants do not emit oxygen at night, but absorb and emit carbon dioxide)

need to. But if you do not want to turn it off, then nothing terrible will happen to the fish.
The aquarium cannot be oversaturated with oxygen and fish do not die from it.
For all questions about aquaristics, you can find the answer in the “Aqu @ world” community http://my./community/aqvamiir/

Are you sure! If you don’t turn off the light: firstly, the fish will have stress, and hence sores, diseases, etc., secondly, the vota will begin to bloom! Or rather, these are microalgae that will fill the aquarium and the water will be like milk and you will have to restart the aquarium. Oxygen oversaturation is impossible! I have light in two aquariums from 11-12 to 9-10 hours.

How to calculate light in an aquarium?

Many aquarists advise setting the light intensity per liter of water. a 0.5 W lamp. In doing so, do not forget to take into account the depth of your aquarium: for fish living at depths, less light is needed than for shallow water.

As practice shows, you can experimentally choose the light in your aquarium, starting from the average 0.5 watts. If there is an excess of light in the aquarium, the water in it will begin to bloom, and the walls will be overgrown with algae. If there is insufficient light, it will be difficult for the fish to breathe, small-leaved plants in the aquarium will begin to die, and brown spots will appear on the walls.

Light in the aquarium

The normal life of aquatic plants and living creatures directly depends on the quality of illumination. And every novice lover of aquarium fish will surely have questions: is there a need for light in an aquarium and why is it needed. Let’s try to find answers to these questions.

In the old days, fish lovers put their aquarium next to a window for better lighting. However, they soon noticed that if the light from the window falls on the fish house at an angle, then its walls begin to overgrow with algae.

Later, with the advent of modern lighting, natural light for fish in aquariums was replaced by artificial light.

In addition to the decorative function, the light in the aquarium also performs an important physiological load. Indeed, for proper development, light is necessary for all living organisms, and its absence causes stress in them.

Is it possible to turn off the light and air for the fish at night, an aquarium of 15 liters of fish 10 pieces, guppies, neons and other trifles)

Guppies and neons can live in such a volume without air for up to a week, just don’t experiment often. Of course, after such a bullying you will not wait for slowing down, but you don’t need it, do you? ) And about the light. you did it, yeah?

there is enough light for 6 hours a day, the light must be turned off at night, the fish must also sleep, they must also have a night. better air is not needed, why stress the fish? from stress, they can develop ichthyophthyroidism. fish sleep at night, hover motionless in the water, relax, and how can they relax without oxygen?

Do I need to turn off the lights in the aquarium at night

Whether or not to turn off the lights in the aquarium at night is a common question that is mainly asked by newcomers to their aquarium business. Everyone needs light, including those in your home aquarium. Of course, for some, light is not of decisive importance, as for example for plants. Our task, as owners of our pets, is to provide them with proper conditions, and light is one of them.
Here you need to understand that aquariums are different, and based on the species composition, it is necessary to adjust the amount of lighting in the aquarium. If your aquarium is dominated by live plants, then they need their own. If the plants are practically absent, then you can vary the light regime more widely.

The lights MUST be turned off at night in the aquarium! The optimal daylight regime should be from 10 to 14 hours, depending on the fish and plants.

For most aquarium fish, light is not required. In wildlife, many fish generally live in the water column, where not much light reaches. Even if you do not turn on the light at all, the fish will not particularly resist this, especially since they will be able to find food thanks to the rest of the senses.

Light is needed primarily by plants. it is light that promotes photosynthesis. And of course, the presence of good lighting allows you to fully enjoy the beauty of your aquarium and its inhabitants.
It is also important to consider the time of year when choosing a light mode. In particular, in winter and autumn, very little light can reach the aquarium from outside.

Light in aquarium with plants at night
If there is an excess of live plants in the aquarium, then the light must also be turned off. Thus, you simulate a living, natural environment for all inhabitants.

24-hour aquarium lighting
Lighting the aquarium around the clock is a realistic option, but we do not recommend doing this. And it’s not about saving electricity.
There is such an option. to turn on the light in the aquarium only at night, that is, in fact, use the aquarium as a night light. But in this case, the aquarium should be darkened during the day. And the inhabitants of the aquarium do not really care what time of day it is. Of course, such an implementation is only applicable if the aquarium is located in a darkened place in an apartment, in a corridor, for example. This is necessary so that the alternation of day and night is observed, otherwise, even with the lights off, enough light can get into the aquarium from the windows in the apartment.

Do fish need light

Among the fish there are species that do not need lighting either day or night. They live at the bottom or in the water column, but deep enough. Accordingly, the minimum amount of light gets there. For example, catfish are nocturnal, they do not like light. Such fish find food well in the dark.

But there are aquarium pets that need light to exist. For example, goldfish without lighting will become pale, lethargic, refuse to eat, and start to get sick.

And in general, in order for pets to live comfortably, it is necessary to create the most natural conditions for them, the presence of day and night in a home reservoir is mandatory. To do this, you need the light in the aquarium to shine

12 hours a day, depending on its intensity.

Whether to turn off the light in the aquarium at night?

The beauty of plants and many fish depends on the lighting. For example, some species of fish will be stressed without lighting, and their colors will become pale. And the plants will stop growing altogether. As you can see, the lighting in the aquarium is not just a decoration, it plays an important role in the development and existence of the underwater world. Let’s try to answer the question, do you need a light in the aquarium at night, do you turn it off??

What problems will appear if you leave the light on at night?

Aquarium lighting around the clock will lead to many problems. Here are the most common ones:

  • Some fish will be under stress under 24/7 light. Over time, this will lead to the fact that they will attack each other.
  • Due to the excess of light, algae will begin to grow in the aquarium. Over time, such a container will look dirty and ugly. Algae overgrowth will kill plants.
  • Fish, like other living things, need darkness to sleep. If they do not rest, they will become inactive.

Do plants need light

Plants will not grow without light. For their development, the light must be on in the aquarium for 8 to 12 hours. At this time, they produce oxygen, absorb carbon dioxide and develop, that is, the process of photosynthesis occurs.

The brightness of the lighting is selected based on the types of crops planted in the aquarium. For example, cryptocarina, anubias, hornwort will grow well at an illumination of 30-40 Lm / l. But there are also more demanding plants that need much brighter light. For example, for the growth of red plants, lemongrass, illumination of 100 lm / l is required. At night, plants don’t need light.

How to control light

To create day and night in the tank, you can use an electronic light timer. It is set to turn off the light in the evening and turn it on in the morning. This is a fairly convenient way, because after setting up you will not worry that you forgot to turn on / off the lighting. The timer will do it for you every day.

Buy only high quality equipment to avoid a fire in the house. The principle of the timer. the relay closes or opens the electrical circuit, if the contact is poor, a spark arises. The mechanical timer works like a clock, wind the spring for example for 8 hours and it starts counting down the time, after which it opens the electrical circuit.

As for the other method, it is based on the fact that you yourself will turn on the light in the aquarium in the morning and turn off the light in the aquarium at night. But it is desirable to do all this at the same time, that is, set the daylight hours.

As you can see, the answer to the question of whether an aquarium needs light at night is quite simple. At this time of day, neither fish nor plants need light.

Risk factors

It is very important to avoid overpopulation, and this depends on how large your aquarium is. If you turn off the air compressor in an aquarium teeming with fish at night, there is a great chance that in the morning you will find several individuals killed from a lack of oxygen. This is due to the fact that one individual has less oxygen in an aquarium with an inoperative compressor, and if it is overcrowded, the chances of oxygen starvation increase several times.

During the day, algae in the aquarium release oxygen during photosynthesis, but at night the situation changes dramatically. plants at this time of day, on the contrary, begin to consume oxygen from the water. Therefore, it is logical to assume that even in a not very densely populated aquarium, the nightlife of fish is complicated.

Do Aquarium Fish Need Light At Night (Probably Not What You Think)

Why disable?

Turning off the compressor at night can have various reasons. the owner wants to save electricity or does not consider it necessary to work at night, believing that the fish are sleeping.

Nevertheless, you should understand that any pets are associated with different expenses, therefore, even before purchasing living creatures, you need to think about whether you are ready for additional items of expenses for living creatures. Fish need their own aquarium, additional lighting and aeration, food and plants to facilitate their daytime existence.

If you have a lot of fish and the aquarium looks overcrowded, you should be prepared to purchase a second one and set aside individuals to avoid crowding and the risk of suffocation.

In other cases, when you have a spacious aquarium with a minimum of vegetation, you can sometimes turn off the compressor at night, but be sure to monitor the reaction of the fish the next morning. Whether they have enough oxygen is easy to understand by paying attention to where the fish swim. If they hovered close to the surface of the water, it means that at night they actively swam up to swallow air.

We take into account the details

The following factors must be taken into account without fail:

  • the size and shape of your aquarium;
  • population with fish and snails;
  • the presence of algae in the aquarium;
  • decorating elements.

The numerical characteristics of the water surface depend on the size of your aquarium. The larger the space, the better the exchange of gases between living organisms and the external environment takes place. In this case, the fish have excellent conditions for life, and the compressor also additionally regulates the oxygen supply.

Thus, it is always advisable to have, if not a huge, then significantly larger aquarium than is required for the number of free-swimming fish. The larger the tank capacity, the less likely your pets will experience oxygen starvation at night if you plan to turn off the oxygen compressor. Try to avoid crowding in the aquarium by any means. move out growing plants, purchase a larger aquarium.

And if the fish are overpopulated, then remove them from the existing composition, leaving only the normalized number of individuals.

Is it possible to turn off the compressor in the aquarium at night?

It is very difficult to say with certainty whether to turn off the compressor in the aquarium at night, as this depends on several factors influencing the decision. For some aquariums turning off will not bring any unpleasant consequences in the morning, while for others it is not recommended to turn off the aeration even for several hours.

We will figure out when it is permissible to stop forced aeration at night, and when it is better to refrain from such a decision.

Based on all of the above, we can conclude that additional aeration can be turned off only in a spacious aquarium with a small population of algae and animals.

In the morning, you can always tell exactly if you made a mistake by turning off the compressor. If it is obvious that the fish have a lack of oxygen, do not let the aeration shutdown anymore.

Remember about plants that consume oxygen at night. if there are a lot of them, they will “take” oxygen from the fish at night, complicating the breathing process.

If you take into account all the above factors and do not miss important points leading to the death of fish, then the additional air supply at night can be turned off. In other cases, the compressor must be constantly running.

You will learn about whether it is possible to turn off the compressor in the aquarium at night in the following video.

Leave the light in the aquarium overnight or not?

After purchasing their first tank, beginners consider whether to turn off the lights in the aquarium at night. Of course, fish, shellfish, shrimp and plants, like other living creatures, need light, but they need it in a certain amount. At the same time, it is necessary to take into account the fact that the duration of the lighting devices operation depends on the phenotypes and types of flora living there.

What will happen if you do not turn off the light

Some aquarists claim that at night the light in the aquarium is needed for fish to search for food in the dark. In addition, night lighting allows you to easily see the inhabitants of the reservoir. Following these assurances, aquarists make a mistake, because fish have special organs to search for food, and besides, most pets sleep peacefully at night. But if an artificial reservoir is illuminated around the clock, then this will cause the following problems:

  • Deteriorating fish health, as pets are programmed at the instinct level to change day and night. Fish need rest at night, and the light in the aquarium will interfere with this.
  • In nature, there is no round-the-clock lighting, and the closer the conditions in the tank are close to natural, the better the pets and plants develop and live longer.
  • Increased level of aggressiveness in pets: some phenotypes, in the absence of a change of day, show increased anger towards relatives.
  • The main problem with round-the-clock lighting is algae. The longer the daylight hours in an artificial reservoir, the faster harmful tiny organisms develop in the reservoir, which can lead to the death of all living things.

Lighting requirements

Lighting in an aquarium is an important factor for the development and life of fish, plants, molluscs. Before deciding if you can turn off the lights in your aquarium at night, you should learn more about the requirements of the fish. Each of the phenotypes is distinguished by individual requirements for daylight hours, since under natural conditions some fish live on the bottom, where the sun’s rays do not reach, while others swim near the surface of the water surface. The light in the aquarium affects the color of the phenotypes: for example, goldfish lose their rich color without lighting.

In addition to these factors, the main argument that turning off the bulbs at night is necessary is the fact that in nature there is no 24-hour daylight hours. And fish in an artificial reservoir implies the creation of a natural habitat, because the more the conditions in the reservoir are closer to natural, the better the fish feel.

In other words, to the question of whether to turn off the light in the aquarium at night, the unequivocal answer is yes. On average, fish require 8 to 12 hours of daylight. If the tank is illuminated by natural light, then it is supplemented with artificial lighting, but direct sunlight is harmful to the reservoir. The illumination at night should be left in the event that the reservoir is located in a dark place. in a room where there are no windows.

Control of the duration of daylight hours

There is also an alternative to light indicators. alarms and timers, which will not let you forget about turning off the lights in an artificial reservoir. With the help of such devices, it is convenient to control the length of daylight hours, thereby taking care of fish and flora in the tank.

When lighting a tank, it is important to observe the following rules:

  • Light mode. the lamps in the pond are turned on and off at the same time every day. Failures in the mode will lead to stress of fish, decrease in vegetation growth.
  • The transition to darkness should be slow, not abrupt. First turn off the lamps, leaving room lighting, and then turn off the light.
  • Duration of daylight hours. no more than 12 hours.

Lighting in an artificial pond plays an important role in the development of living organisms, however, excess light will harm pets, so the lights in the aquarium should be turned off at night. Light timers and alarms will help control the length of the day and night in the tank, which are convenient to use, and independently turn off or reduce the saturation of light radiation.

Light in the hen house in winter

Most chicken owners know that in the fall they have a slowdown in egg production. This is because daylight stimulates the chicken’s pituitary gland, which then stimulates the ovaries to produce eggs.

The hen needs 12-14 hours of daylight to achieve maximum clutch efficiency. Thus, shorter days and less sunshine means that the performance levels of the laying hens are reduced and sometimes even stopped.

One of the solutions that some poultry farmers (as well as most commercial egg producers) use to create artificial conditions for increasing light time is to light in the hen house at night, more precisely in the morning and evening in order to get more eggs.

This trick misleads the chickens’ biological clock into thinking that summer is still going on. This is one method that almost certainly guarantees an increase in egg production during the winter.

24-hour aquarium lighting

There is such an option. to turn on the light in the aquarium only at night, that is, in fact, use the aquarium as a night light. But in this case, the aquarium should be darkened during the day. And the inhabitants of the aquarium do not really care what time of day it is. Of course, such an implementation is only applicable if the aquarium is located in a darkened place in an apartment, in a corridor, for example. This is necessary so that the alternation of day and night is observed, otherwise, even with the lights off, enough light can get into the aquarium from the windows in the apartment.

If there is an excess of live plants in the aquarium, then the light must also be turned off. Thus, you simulate a living, natural environment for all inhabitants.

How to bring light into a barn: the necessary materials

Now we move on to the second stage and prepare all the necessary materials.

It will start with a wire, we recommend using VVGng, it has increased protection and will serve you for many years. The junction box must be waterproof. this is an important point.

Do not forget that all devices must be well protected. And of course, we do the correct calculation of the cable cross-section. We recommend installing economical lamps, here you can include: LED and ordinary housekeepers. The light in such buildings can burn for a long time, so it is important to save money on this once again.

Coop lighting time

If you keep chickens to produce eggs for more than one season, it will still be advisable to give them rest in the winter from laying (although they, of course, will lay several eggs, but not as many as they did in the summer).

domestic chickens should be as natural as possible, this includes ensuring their natural life cycle. If you plan to get eggs as seasonal products (like any other “harvest”), then this approach makes sense.

From a purely practical point of view, it can be understood that people would like to get as many eggs from their chickens as possible. Therefore, when deciding to use additional lighting in the chicken coop in winter, make sure that all electrical equipment is completely safe and well installed.

An important factor in egg production, in addition to lighting, is also the heat in the hen house, so you should insulate the hen house for the winter, not forgetting about good ventilation.

Provide the chickens with a complete and rich in vitamins and calories complementary foods so that the chickens can easily cope with the additional loads during winter egg-laying. Also, consider purchasing cold-tolerant chicken breeds that are natural to lay in the winter.

At the end of the day, just make sure that all pets are as well fed and healthy as possible. After all, happy chickens are abundant eggs.

Many novice poultry farmers are interested in such pressing questions as. is there a need for light in the chicken coop in winter, how long should the light be on. only at night or around the clock, and whether to leave the light on at all overnight? In this article, we will consider all the reasons and nuances of the role of lighting in general, as well as find out what lighting time is optimal for chickens.
