Is it possible to fill the aquarium with filtered water

Distilled and rainwater

Since springs are very hard, maybe it is better to fill the tank with soft water. rain or distilled? Again, not always. just mixing it with the tap. There are fish that love a softened water environment, but many freshwater species still prefer medium, neutral water. Such water flows in domestic rivers and lakes. its purified water can be poured into an aquarium, not filling all the space with it.

Watch the video on how to change the water in your aquarium.

Purification of water in the aquarium

It is not enough to simply prepare the water and pour it into the aquarium. It requires follow-up care, which includes filtration and ozonation. The following types of filters are considered the most common:

  • Internal. The most budgetary, and therefore the most common option. It is a pump that displaces liquid through a filtering composition made of a foam rubber sponge
  • External. They are more often bought for large volumes. They do not take up unnecessary space inside the aquarium and have large volumes of filter media. Sterilizers are also installed on the external filter.

Can you turn off a fish tank pump at night?

As you can see, the collection of water for the aquarium and its further control is a simple process.

What habitat do aquarium fish like the most?

What kind of water is needed for an aquarium? By combining water from different sources, it is impossible to achieve ideal parameters. How many fish, so many requests. Some fish can live in melt water of mountain lakes, others in brown marsh water. In the first case, the water is very hard, in the second, it is soft. The fish have to be settled on a different environment. It turns out that some fish are orderlies who love rotten water, others do not tolerate such parameters. A rotten environment is destructive due to humic acids. Many freshwater biotopes in our country have pH neutral water, medium acidity, low alkalinity. Suitable for most aquarium fish.

Choosing water for an aquarium

There is no absolutely pure water in the world; it is extracted in laboratories using step-by-step distillation. Water from a tap or a natural source always contains impurities of various substances that play an important role in the ecosystem. Considering that many modern people keep fish at home, everyone wants to use the highest quality water for them. But what should be the water so that it can be poured into a home aquarium?

What you need to know about spring water

For a long time, it was believed that spring water, drawn from a crystal clear stream, is best suited for ornamental freshwater fish. Perfectly clean, transparent, odorless and without dirt. this is exactly how you can fill a container! It turned out that typing this is not always safe. Its difference from tap water is its high hardness. Even soap dissolves in it with difficulty, to say nothing of fish food. Due to the high content of magnesium and calcium salts, it has a detrimental effect on the health of fish and their offspring (eggs). Unfortunately, it is not recommended to add spring water to an artificial aquarium. Sometimes it is mixed with tap water to increase the hardness.

Aquarium water for unpretentious fish

Water, which must be prepared for not very whimsical ornamental fish, requires preliminary preparation. It is necessary to fill the general aquarium with soft (sometimes medium hardness) pH-neutral water. This can be regular tap water. Spawning and viviparous fish take root well in it, which perfectly adapt to different conditions.

See how to change water and maintain your aquarium.

The degree of hardness can be measured with litmus paper, the temperature of the water with a thermometer. It is recommended to mix water with a high degree of hardness with soft rainwater (filtered) or distilled water. Water from pure melted snow or ice is also suitable. The listed types of water can be taken into a clean container only after prolonged precipitation, it is enough to pour 30% soft water into infused tap water.

Tap water must not be poured immediately. It is better to pour it into a glass and see if the glass is covered with bubbles, if there will be a strong smell. Such water is saturated with compounds of gases that got into it during the filtration process at the treatment plant. Having let the fish into such a liquid, the pet’s body will instantly be covered with bubbles, which will penetrate the gills and internal organs. As a result, the fish will die. In addition to gas, chlorine is mixed into the water for disinfection, it will also poison living beings.

To get rid of gases, tap water can be poured into glass containers and allowed to stand there for several days (2-3 days). There is another quick way: pour water into an enamel bowl, bring it to 60 or 80 degrees on the stove, set aside and cool. Boiled water is harmful. it leaves limescale from calcium and magnesium carbonate on the walls of the dishes. Boiled water can be poured into the spawning grounds, but in extreme cases. It will take a long time to fill the entire area of ​​the aquarium with boiled water. Another nuance. boiled water kills all useful microflora.

If you do not have water supply (this is also found in our time), you should go to a clean river or lake (where there are no signs “Swimming is prohibited!”, Etc.), and take water from there. If it is clean, river fish (perch, bream, roach) really live and thrive in it, there is a water mesh plant, this is a good sign. To destroy parasites, such water is heated in an enamel bowl to 80-90 degrees, but do not make boiled water out of it. In terms of parameters, it will differ from the liquid from the tap, so think about whether it is worth taking such a risk. You can go to another house and collect running water there.

In addition to thawed, spring, rain and distilled, it is advisable to pour 30% of the water from the old aquarium to the infused liquid from the tap. If it was kept safely, the fish and plants were not sick there, the water in it did not grow cloudy. this is a godsend. In the old (residential) aquarium water, whether it was poured for a long time from the tap, there are many beneficial microbacteria that will create a natural biological environment in the new home. The living aquarium environment contains a number of organic impurities that are very beneficial to the aquatic environment. They make the water more acidic, prevent putrefactive and pathogenic bacteria from multiplying. If high-quality and proven water is poured into the tank, all its inhabitants can be healthy.

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.

Aquarium filter stopped during the night.

Do I need to turn off the backlight and filter in the aquarium at night.

Tell me, you love peace and quiet at night. I think you hardly sleep with the light on. Therefore, it is advisable to turn off the filter in order to reduce the noise level in the fish tank, as well as turn off the lights. As you can see, all the activities are not only attractive to fish, but also save energy πŸ™‚

You can turn off the backlight, but it’s better not to filter, because firstly, it cleans the water from all dirt and garbage, then it saturates the water with oxygen, which is necessary for fish, although they don’t breathe air, but oxygen in small amounts to them All the same, you need it, and the power filter itself almost does not eat, there is quite a bit, so do not be afraid of the filter, the thing you need.

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.

How to choose an aquarium lamp?

There are several options for aquarium lamps:

  • incandescent lamps are the worst option, they shine poorly, but they heat up a lot;
  • fluorescent lamps do not fully provide the required illumination spectrum;
  • phytolamps provide the required light intensity, but their cost is quite high;
  • lighting with LED lamps is closest to the sun. It maintains a stable water temperature. With their help, you can adjust both the brightness and the spectrum of light illumination in the aquarium.

Does the light turn off at night in the aquarium?

The light of course needs to be turned off and there is also such a thing as daylight hours. It is necessary for plant growth (average about 14 hours). But you can deviate from these norms, you can make a night light from the aquarium, then very weak bulbs with neutral illumination are used (color spectrum). And the main lighting works unambiguously on time.

there is such a thing as daylight hours in an aquarium

There is also a recommended aquarium lighting technique called “Dark Pause”, which is successfully used in practice by some aquarists, its essence is as follows:
In the morning, the aquarium is illuminated for 4-5 hours, then the light is turned off, making a dark pause for 2-4 hours, after which the lighting is resumed again for 4-7 hours. During such a break in the “dark pause”, the aquarium does not need to be completely darkened, but the lighting should be limited to only diffused light from the window at a distance of 2-3 m or a weak incandescent lamp.

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.

The light should be turned off at night in the aquarium.?

Yes, the lights must be turned off at night. Fish also have a need for sleep and sleep. Of course, they can sleep in dark places, under bushes or in shelters. Nevertheless, the light prevents them from sleeping. There are also nocturnal species that feel good and feed at night, these are many types of catfish and catfish, loaches, constant lighting interferes with them.
Living plants also require darkness, because in the dark phase they breathe oxygen just like animals, do not forget the dark phase is necessary for plants to live.
From my experience I know that in exhibition aquariums where the light is constantly on for a couple of months, living plants begin to be oppressed and die, and the fish start to get sick, because constant lighting is stress (in nature this happens only in polar conditions)
For the normal life of the aquarium, it is quite enough to darken for 2 hours a day.

Is it possible to turn off the filter in the aquarium at night and for what reasons?

It has been about two centuries since aquariums appeared in Europe. But attention to exotic fish continues unabated. A large, beautifully designed aquarium is a prestigious decoration in any home and a great stress reliever.

An aquarium is an unnatural closed water world with its own complex ecological balance. To maintain a comfortable life for fish and algae, the water in the aquarium must be filtered with high quality, as well as its regular replacement at intervals of about once a week. Stability and quality of filtration in a home pond is ensured by a special purification filter, consisting of a pump and a container with filtration material. In this article, we will consider the selection criteria, care and answer the question of whether it is possible to turn off the filter in the aquarium at night.

Filter selection for cleaning

Before buying a water purification device, you should decide on the number of future residents of the aquarium, what plants will be present there and whether the filter can cope with water purification and removal of sewage.

possible, turn, filter, aquarium

Optimal filter criteria are minimum size, reliability, serviceability, maximum efficiency. The price of the product and the manufacturing company are also of great importance when choosing.

Usually, after buying such a filter, you no longer think about the quality of water purification from impurities and mechanical impurities. But because of their price, such devices are of little relevance.

The middle price segment is represented by a large number of models. These are practically all European brands: Aquael, Ferplast, Sera and many others. Such filters are more affordable and will last long enough.

Unknown and inexpensive manufacturers mainly from China. How they will work, how much water they can filter. nothing definite can be said about them. Usually, such devices are bought as temporary or spare to replace those that have failed.

Disabling the filter at night

In addition to cleaning from unnecessary impurities, the unit has another important function. it is to saturate the water in the aquarium with air. In the closed space of the aquarium, in addition to fish, beneficial bacteria grow, which have a positive effect on the eco-balance. In the absence of oxygen, they begin to die and decompose, while releasing chemical compounds that are harmful to the population of the aquarium.

Therefore, it is categorically impossible to turn off the pump at night. the device must work constantly. Short-term shutdown of the filter pump for maintenance is allowed.

If the pump is always running (around the clock), then the biological balance in the aquarium is maintained in a stable state. The water stays clean for a long time, the fish are healthy.

If the air supply is cut off for extreme reasons, for example, a pump breakdown or a power outage, aquariums with a volume of more than 50 liters will tolerate this situation without any problems. For smaller aquariums, this can be a huge hazard. With a single shutdown, large aquariums will cope with the problem, but if you turn it off often, then fish diseases or even death can happen in the near future.

Work principles

Filters are of various types, they are divided into bottom, external, hinged and internal. The filter material and design also differ. In turn, the efficiency, noise is of great importance.

Indoor models are usually installed inside domestic waters, are small in size, low in performance and low noise floor. Maintenance is easy and convenient.

Outdoor cleaning units are placed next to the aquarium. Due to the larger size of the filter element, water purification is much better.

The main purpose of the hydrofilter is to circulate water in the aquarium and remove waste products of fish, turbidity. No matter how different devices are in appearance and design, they have a common principle of operation:

  • water with impurities is drawn in by a water pump;
  • cleaned mechanically or chemically;
  • the treated water flows back into the tank;
  • forcibly and evenly mixes water layers.

All these parameters affect the ease of use of the unit, the speed and quality of cleaning the aquarium liquid.


Colonies of beneficial bacteria live in the filter container, so cleaning must be treated with great care. It is undesirable to use detergents when washing the pump and filter.

The frequency of such filter maintenance is influenced by the number of fish living in the aquarium.

The easiest way to determine if a filter needs cleaning is to pay attention to the air pressure coming out of the flare. If he’s weak, then it’s time to do it.

To flush, unplug it and remove it carefully so that impurities and food residues do not fall to the bottom of the aquarium. Then disassemble the pump, rinse the internal parts and the filter element. Then reassemble everything in reverse order and put the unit back in place.


The reasons for the incorrect operation of the filtering complex may be different. Let’s consider the main ones, as well as ways to eliminate the problems.

  • Filter clogged with waste from the aquarium population. The operating time of the device is not unlimited and very much depends on the location in the aquarium and the quality of the water. A sure sign is a drop in air pressure at the outlet of the pump. Corrected by regular cleaning or replacing the filter when worn. The place of installation is important. The unit must be completely submerged in water, but not touching the bottom so that soil or other elements do not fall into it.
  • Low electrical voltage. The pump operates with power fluctuations. Eliminated by installing a device that stabilizes the voltage in front of the consumer.
  • Breakdown of the pump. Water stops circulating even with a clean or new filter. The solution is to replace the pump. In no case should you try to repair it yourself. It is recommended to take it to a workshop for repair or purchase a new one.

Whether it is necessary to change all the water in the aquarium or only a third part??

Never change all the water. This will restart the aquarium. Depending on the frequency of cleaning and the volume of the aquarium, it varies from 1/10 to 1/3 of the aquarium. 1/3 is the maximum.

In the morning I wake up, and there is a toracatum catfish on the floor near the aquarium. 10 cm and two sword-nosed women. Why and what fish can jump?

There are two reasons.
1. Poor water quality (nitrates, nitrites).
2. High temperature.
Under normal conditions, the fish does not jump out of the water. It happens when the male chases the female, and then rarely, but so much at once. Look for a problem, test the water and measure the temperature.

Is it possible to turn off the filter in the aquarium

Do I need to turn off the filter compressor at night?

Not. The filter compressor must work around the clock. Fish breathe at night too.

Aquarium 120 liters, after the death of the fish, 2/3 of the water was replaced, the filter was washed, sera biocultures for filters and aquariums were added. The aquarium stood empty for four days with constant filtration, temperature 24. Gold and a veil tail are worn after disembarking from the can throughout the aquarium, the telescope immediately lay down on the bottom. I put him back in the bank, he sometimes lies moving. We also have water with elevated chalk in our tap, I heard golden ones do not tolerate limestone.

If there was really bad water, all the fish would not be very good. Two feel great, one bad. So it’s the fish. Perhaps a weaker immune system, and against the background of everything. bacterial infection. Buy Tetra GoldOomed and treat in a separate container according to the instructions.

You cannot determine the hardness of water by eye, buy Tetra test strips and measure the total and carbonate hardness. You can soften the water by adding boiled water or adding Tetra ToryMin. In the latter case, the water will take on a slightly brownish color. You can put natural roots of mangroves in the aquarium, they also soften the water.

If the aquarium is not big, what kind of algae is best to plant so the fish don’t eat it? Guppies and gouramis live in the aquarium.

For the growth of hard-leaved plants, conditions must be created that cannot be met in a small aquarium. You need special lighting, soil fertilization, and these plants themselves are quite large. Gourami will eat any plants, guppies also “do not like” to eat weed. In order to preserve at least some plants, include more plant foods in the fish diet. This will not save you from eating at all, but they will nibble less.

After a month of cohabitation of a speckled catfish with a cockerel, the cockerel bit off its antennae on one side (captured part of the muzzle). Is recovery possible?

The cockerel must be planted, and the catfish must be dripped with methylene blue. Make a light blue solution and let it float for 5 days. Then make a change. Must grow mustache.

External Filters

Suitable for both compact and large aquariums. In most cases, they are equipped with fairly capacious canisters, which makes it possible to use several types of fillers, which allows you to achieve better water purification. In addition, the location of the device outside the aquarium will not occupy its usable area and scare off fish with unnecessary noise.

Two hoses are attached to the canister. One of them is for the intake of dirty water, it is connected with the other end to the pump, and the other. to feed it into the aquarium after cleaning. Compared to other types, these filters are more expensive, but these costs pay off. Correct installation of the filter in the aquarium and the use of quality materials will allow cleaning the tank once every 5-6 months.

Aquarium bottom filter

Consists of drainage pipes, a pump and a porous plate on which a layer of soil is placed. The main advantage of this filter. invisibility, which allows the fish to feel comfortable, and the interior of the room and the aquarium is not disturbed by unnecessary details. However, it is rarely used, mainly only in the smallest aquariums. The main cons:

  • To clean the filter, it is necessary to completely empty the aquarium from water and temporarily relocate the fish.
  • Too much water circulation at the bottom can harm plants because it over-oxygenates them.

What is an aquarium filter?

This is a structure that is installed either inside the aquarium or next to it. It consists of a compartment for filter media and an electric pump that promotes the movement of water and various fillers. They are based on materials that trap debris, chemicals or special bacteria. Each of the filtering methods has its own strengths and weaknesses. In addition, the selection takes into account the volume of water that the aquarium filter is able to process without replacing elements in accordance with the dimensions of the tank.

Cleaning the filters

Its frequency depends on the number of inhabitants in the aquarium. On average, the internal filter is cleaned once a month, while the external filter is cleaned once a month. once every two to three months. Care should be taken when cleaning biofilm to avoid killing beneficial bacteria. Processing of this element is carried out in aquarium water. The rest of the elements can be washed with tap water using a brush. In this case, you cannot use disinfectants, their traces can get into the aquarium and pose a threat to the health of fish.

Installing a filter in an aquarium: rules and recommendations. How to position the filter in the aquarium

Installing a water filter in an aquarium

The internal filter is installed in the aquarium using special suction cups. The device should be completely immersed in water, the distance between its surface and the filter should be at least 5 cm. Only the tube through which oxygen is supplied is brought out. Remember that the filter must not be connected to the mains during installation to avoid electric shock. In order to adjust the air circulation sensor, you need to know what kind of fish will live in the aquarium. Some of them need a more intense flow, while others need a slower.

The installation of an external filter in the aquarium begins with assembly according to the instructions. If it is multistage, then it is important to fix the cassettes in the correct sequence: a porous material is placed at the very bottom for mechanical cleaning, then a biological filler made of finely porous material and a chemical one are installed. The final stage. connecting pipes and filling the filter with water. After that, the device can be connected to the network.

Helpful hints

  • The filter must not be connected to the network without immersion in the aquarium, its electrical system quickly overheats without water.
  • Do not turn off the filter for a long period of time. In this case, not only dirty water is a threat to the inhabitants of the aquarium, the filter itself, which turns on after a break without rinsing, can also cause harm. Pathogenic bacteria can form there, which will instantly lead to the death of the fish.
  • The external filter and the aquarium should not be located in areas where direct sunlight is falling. Excessive heating will contribute to the formation of harmful chemical impurities in the aquarium, the reproduction of poisonous algae.
  • If several filters are used in a large aquarium and it is time to clean them, then it is recommended to process them one by one, this will maintain the correct biobalance of the entire aquarium system.
  • Do not rinse the elements of the filter structure under a direct stream of water, boiling water is contraindicated.

Caring for your aquarium filter. How to properly clean your device?

The aquarium filter is the most important piece of equipment.

The well-being of all the inhabitants of the aquarium largely depends on how effectively it carries out mechanical, biological or chemical water purification.

To maintain its full function, the filter must be regularly looked after. And an important part of grooming is proper cleaning.

possible, turn, filter, aquarium

How to wash properly?


  • Disconnect the filter from the power supply.
  • Disconnect the filter carefully from the hose system for water supply and drainage.
  • Remove the filter from the cabinet.
  • Disconnect the filter pump from the filter baskets.
  • Remove all baskets one by one.
  • Disassemble the mechanical part, remove the rotor.

Do I need cleaning?

The aquarium filter must be cleaned without fail, regardless of its type and features.

Passing through and purifying water, he himself gradually becomes more and more polluted. Filter material, tubes, impeller and other parts are clogged with filtered dirt, residues of decomposing organic matter, and harmful substances. This leads to the fact that the efficiency of the filter decreases over time.

At some point, it stops cleaning and starts releasing dangerous toxins into the water. This leads to severe disturbances in the biological balance of the aquarium and all kinds of diseases of its inhabitants.


  • If the filter media is large enough, it can be washed without removing it from the basket.
  • It is better to rinse fine filler (ceramics) by first pouring it into a small bucket. The water used for cleaning is warm and clean (hot water is not allowed).
  • Fillers that cannot be cleaned or worn out, which have expired (check the instructions on the packaging), replace with new ones.
  • After rinsing all baskets one by one, start cleaning the main container.
  • Remove slime and dirt from all mechanical parts, including the impeller and the pin on which it is attached.

How to assemble?

The internal filter is assembled in the same way, but in reverse order.

An important aspect is that you need to disassemble, clean and assemble the filter as quickly as possible. In this case, it is still worthwhile to act carefully and thoughtfully. This will cause minimal damage to the bacterial colony. This means that full biological filtration will recover much faster after cleaning.

The external filter is also assembled in reverse order. However, when assembling it, you need to consider a few points:

  • Strictly observe the correct position and sequence of the filter baskets.
  • The upper and lower parts of the filter must fit tightly to each other, without distortions.
  • All locks should be easy to close.
  • You can start the filter only after making sure that it is filled with water.
