How to properly restart the aquarium with fish


Restart Aquarium

In the practice of keeping ornamental fish at least once, there came a time when it was necessary to restart the aquarium. This can be confirmed by almost every aquarist. The reasons are different, and the operation itself to stop and restart the home aquatic system requires knowledge and quite a considerable amount of time.

Aquarium restart: possible causes

What distinguishes the launch of the aquarium from the restart? Yes, almost nothing, only when restarting the aquatic system, it is first subjected to full maintenance - cleaning and disinfection (if necessary) of both the can itself and its internal contents.

It is believed that this operation should be performed periodically, regardless of the condition of the functioning aquarium. Some owners of ornamental fish believe that in their homes it is necessary to carry out general cleaning from time to time, cleaning out dirt and debris.

Opponents of this point of view believe that an aquarium, if you follow all the necessary rules for keeping fish and plants, should function without stopping and re-enabling, and it should be restarted only in exceptional cases that are not urgent.

What could be the reasons for restarting a fish tank?

First of all, it is carried out if the water is very turbid, the walls are overgrown with algae, and filtration and volume changes do not positively affect the situation.

Secondly, with strong acidification of soil, if its cleaning or replacement is impossible in conditions of continuous operation.

Thirdlyif ornamental fish or aquatic plants become infected with infectious diseases, as well as in the case of the death of living creatures.

Fourthif the existing internal design is tired and there is a desire to replace it completely.

Fifthwhen the bank began to flow or other technical reasons appeared. In this case, you need to restart quickly.

Quick restart

It is carried out not only because of leaks, but also for other reasons, when stopping the operation of the aquarium does not suffer delay.

What to do with fish

The first settled fish. If the old aquarium water is suitable, then it is poured into a tank (a large jar, a spare aquarium), and fish are allowed in there, constantly observing their behavior.

When the old water does not fit, then pour in at least 2 hours (at least) ordinary water settled in the bailout. If there is distilled water, then add it. The water is heated to the required temperature.

Seasoned aquarists also recommend adding a commercial air conditioner, AquaSafe from Tetra, to aqua. Fresh water is poured into pre-prepared containers for further launch, which in urgent mode should be defended for at least 8 hours.

Aquarium flora, soil and scenery

Plants, if they need to be preserved, are temporarily transferred to a separate vessel. It is necessary to carefully remove them from the ground without destroying the root system.

Then gently get the ground. It must then be rinsed in hot water or (if necessary) calcined in the oven.

Elements of the decor can be washed in salt water.

the washing up

Next, proceed to cleaning the working banks. In the bathroom, the aquarium is washed several times with hot water. Use of cleaning chemicals is undesirable.

The glass surfaces are dried with a soft cloth and then proceed to repair the breakage or malfunction.

After that, ordinary water is poured into the container to check the tightness. Two hours is enough for this, and then it merges.

Directly restart

The system is preparing for launch: first, the washed soil is carefully laid down, the settled water (or the old one, if it is suitable) is poured to a level 10-15 cm above the ground. It is necessary to fill it in such a way that the stream does not erode a layer of soil, it is better to substitute a shallow dish and supply water with a gentle stream.

Aquarian plants are washed with warm water and planted in the ground, fit the decor elements.

Then they mount the aquarium equipment, and when using the bottom filter (it is installed before the layout of the soil). Do I need to rinse the filter itself?

With the help of a net, the fish move to their home, the water level is brought to normal in two or three times. If the living creature felt normal in the tank, then some water from it could be used to fill the working aquarium.

Then you can include equipment for heating, aeration and filtration. The first 2-3 days you need to carefully monitor the behavior of the inhabitants and the state of vegetation. Water changes during this period, it is desirable to make daily up to 10% of the total.

Approximately in the same way they are processed in case the walls and the bottom are overgrown with algae.

Restarting the aquarium after fish disease

So, due to some circumstances, signs of fish disease appeared. First of all, you need to catch all the sick fish and transplant it into another aquarium (quarantine), flooding it with separated water. After ensuring the appropriate temperature regime proceed to the treatment of living creatures.

Do I need to change the water and disinfect the aquarium? It is necessary if the disease is infectious. If there is no infection, and diseases are caused by certain types of parasites (for example, flukes, ciliates), then these actions are not needed.

You should not interfere in natural processes once more, you need to give the aquarium a breather for 10-15 days, changing the water for 30-80% of the normal volume and clean the filter. In the aquatic environment, it is necessary to maintain the temperature not lower than +25 degrees all the time, to turn on the aqua filter.

After treatment in quarantine, you can restart the system by moving the treated animals.

Restart aquarium disinfection

This process is the most time consuming. It must be produced if the causative agents of infectious diseases dangerous for fish and plants have settled in the soil, on plants and interior decoration details.

As in other cases, the fish are moved to a quarantine vessel, where they are treated. All other parts of the aquatic system are subject to mandatory disinfection (the tank itself, inventory, plants, soil, filter, thermometer, aerator, design objects).

In the jar, you can pour water with detergent in the proportion of 400 g of powder per 30 liters of water. All surfaces are thoroughly rinsed, and then the aquarium is rinsed several times with warm water. After that, new clean water is poured, which costs a day, then is drained.

What to do with vegetation?

If, as a result of the disease, aquarium plants do not destroy (such an outcome is also possible), then they should be disinfected and treated with penicillin solution. It is prepared in proportion to 50 liters of the drug per 10 liters of water. This operation should be carried out in a separate container with a temperature of the aquatic environment of +25 degrees for 6-7 days.

Many aquarists who are forced to disinfect, get rid of the old soil and fall asleep new. But if there is a desire to preserve the used soil, it must first be washed several times in warm water, separating the mechanical debris, and then calcined in the oven for half an hour.

Summarizing, we can say that a complete restart of the aquatic system is not done often, depending on the circumstances. But it is better not to bring the situation to the extreme, precisely following all the recommendations on the maintenance of fish and plants, timely and efficiently performing the necessary measures to maintain a home aquarium.

Running aquarium

Many, wanting to get an aquarium, believe that the fish - those pets that bring the least trouble. And only experienced aquarists know that this is far from true. Many people are convinced by their own experience that launching an aquarium is a complex process that is built up depending on a large number of factors. However, those who start, making the first launch of the aquarium, do not even suspect about all the stages that should precede such a joyful event as the launch of fish.

Start the aquarium correctly - the first task of the aquarist

Many reference books and manuals tell you how to run an aquarium. But in order to apply this knowledge gained in practice, it is not enough to increase the number of all the components necessary for the livelihood of an aquarium in proportion to its size, area and the number of its future inhabitants.

And even, at first glance, a successful launch can turn into frustration and death of the inhabitants of the aquarium. This happens because the created aqua-system is not supported properly and its initial parameters are lost.

To avoid this, the aquarist should understand the processes of this small ecosystem. It is worth noting that the larger the ecosystem, the easier it is to maintain balance in it. Of course, the number of fish and other organisms living in it plays an important role in its sustainability, but often for the sake of diversity it is necessary to manage to maintain rather fragile ecosystems.

Soil, plants and snails: first

Preparation of the aquarium for launch begins with the introduction of soil into it

The added tap water for some time should just be left in the aquarium so that it will settle. The duration of this period for supporters of traditional methods is several days. At the same time, there are special modern tools, adding which you can shorten this period to one day and carry out a quick launch of the aquarium.

Then the water is inhabited by microorganisms that are involved in the processes occurring in the water. To make this process faster, it is recommended to turn on the filter and saturate the water with air.

After the water is saturated with the simplest life, unpretentious plants are planted in the ground. And although some types of plants are quite acceptable to transfer the landing before filling the aquarium with water, it is better to do it after. Plants should not be much.

Together with the planting of plants, you can begin to turn on the light for a short time: 4-6 hours.

A day later it will be possible to launch snails into the aquarium. Thanks to the products of their vital activity, the number of bacteria will increase, which will help to establish equilibrium in the nitrogen cycle.

Only in 3 weeks from the moment of launch it will be possible to plant half of the total planned "green spaces". At this time, there will already be enough light for them, and they can no longer upset the balance.

Let out in the aquarium fish

Launching the aquarium, each owner is looking forward to the moment when it will be possible to run fish into it. After a few days from the very beginning of the process, it is possible to increase the lighting time of the aquarium to 9 or even 12 hours. At the same time, unpretentious types of fish are launched. Their number should not exceed one third of the population allowed for the selected aquarium volume. With the proper start of the aquarium, it is very important not to feed the fish at this time. It will not suffer from such a forced starvation diet, but it is easy to break the forming nitrogen cycle by feeding, which will lead to the need to restart the aquarium. It will be possible to organize food for the fish only 4 days after their stay in the emerging ecosystem.

A few days after the launch of the first fish, you can populate the aquarium with fish in half of their estimated number. At this time, it is already possible to release more capricious species of fish - the threat to them is minimal.

At the same time, it is already worth replacing one-fifth of the water, and at the same time siphoning the primer. It is also time to rinse the filter.

A week later, all the fish will be planted, the same amount of water will be replaced again, the filter cleaned and the soil cleaned.

Nitrogen cycle

The decomposition products of fish and other macro-organisms living in an aquarium, when decomposed, are converted into ammonia, which is dangerous for them at even low concentrations. This is such a toxic compound that its concentration at the level of 0.2-0.5 mg / l is fatal for the inhabitants of the reservoir, and when the content of ammonia in the water in a proportion of 0.01-0.02 mg / l in fish, immunity is significantly reduced. As a result, they become very vulnerable to all sorts of diseases and parasites.

Proper start-up of the aquarium is aimed at ensuring that microorganisms inhabiting the water could process the entire volume of ammonia. Then it practically will not be in the aquarium, which can be verified with the help of special tests.

The role of bacteria in the nitrogen cycle

The preparation of the aquarium for start-up must be carried out primarily because in the new aquarium the volume of ammonia grows very quickly and the fish, getting into such conditions in most cases either die immediately or start to hurt. In this case, only the restart of the aquarium can help.

The process of reproduction of beneficial bacteria can be accelerated in several ways. Traditional: add water and dirt from the old one to the new aquarium. Along with them will be made a significant number of bacteria, which then inhabit all of its volume. If there is no other aquarium, the bacteria can be bought at a regular pet store. The process of their reproduction is accompanied by the appearance of the effect of turbid water. Launching a new aquarium for the first time, at this time you can make a big mistake: change the water. This is not necessary. The water will become clear again in a couple of days.

The initial stage of the aquarium start-up cycle averages two weeks, during which the number of bacteria increases, but not as rapidly as in the first days.

The overgrown population of bacteria successfully processes ammonia into nitrites, which are also toxic, but to a much lesser extent. Other beneficial bacteria recycle nitrites and they are converted to nitrates, which are also toxic. Both nitrites and nitrates can reach a critical volume when they adversely affect fish.

To avoid further restarting the aquarium, which is also associated with significant inconveniences, it is better to carry out a slow start of the aquarium from the first time and not rush to populate it with fish.

The role of filters in the nitrogen cycle

cleaning filter

External and internal filters are installed in aquariums. They are divided into those that carry out mechanical purification of water from protein suspensions, and there are biofilters.

The main function performed by biofilters is to create conditions for the successful reproduction of bacteria, which should always be in water in large quantities. They populate the filling filter, as a rule, porous materials. Together with water, they receive oxygen and food in the form of protein deposits. The launch of a new aquarium is accompanied by another event: the connection of the biofilter. When you turn on the filter in the first few weeks (up to a month) the amount of nitrite and nitrate in the water increases. This factor during the first start of the aquarium in inexperienced aquarists often causes the death of fish, which is simply poisoned by toxic substances.

Proper Aquarium Care - Disinfection

Do not forget that the aquarium is a real home for fish. He, like the human home, needs cleaning. If a person can provide himself with cleaning often, then this luxury is not available for fish, so the owner should be engaged in disinfecting the aquarium and monitoring the condition of their pets. Many people know about it, but not everyone knows how to disinfect an aquarium correctly.

Primary events

The first disinfection of the aquarium occurs immediately after you purchase the tank. The future home for fish must undergo a thorough treatment before the first inhabitants of the flora and fauna appear there.

How to carry out the initial disinfection:

  1. Fill the aquarium with plain water.
  2. Dilute the solution of potassium permanganate to a dark color and pour it into an aquarium filled with tap water.
  3. After that, leave it for a day. During this time, all pathogenic bacteria will die.
  4. Drain all the water and wipe dry the walls with a dry cloth.
  5. Rinse it several times with clean running water.

The next step will be the preparation of water for the launch of a new aquarium. To free chlorine out of the water, you must defend all 100% of the water for at least 3 days. Then pour and wait a couple of days. Only after this water will be ready to accept the first inhabitants.

In order not to waste time, prepare the rest of the equipment and decor for your exclusive reservoir. Do not forget, they also need to be thoroughly disinfected before they end up in the same water as the fish. Particular attention is paid to the ground. As it is most often used sea sand and pebbles collected in natural conditions. Of course, in the substrate collected a huge number of pathogenic bacteria that will poison the entire environment in the water. To defeat the negative consequences you need to ignite the soil in the oven or in a large frying pan. Exposure to maximum temperature should be all the soil and at least 20 minutes. For convenience, divide it into portions. Do not put the hot sand in the aquarium! Cool and rinse thoroughly. One washing is not enough, it is better to repeat the procedure 3-4 times, only after that you can put it in the aquarium. Do not ignore this stage of the initial launch of the aquarium.

Among the mandatory elements of the normal functioning of an artificial reservoir are accessories. Collect all the elements of the decor, excluding plastic options and boil them thoroughly. Since plastic parts can melt from heat treatment, it is better to process them with a dark solution of potassium permanganate.

Disinfection Flow Measures

In the event that the aquarium is already functioning, but a nuisance has happened and various bacteria and algae have begun to appear in it, then disinfection cannot be avoided. It is urgent to save plants and fish from there.

All the fauna that was in the infected aquarium should be treated with an antibacterial solution. The most popular is a mixture of 10 mg of penacilin per 2 liters of water. Soak plants in it for about 3 days. Do not be afraid, nothing terrible will happen to plants during this time. The aquarium itself can be disinfected with a special bactericidal lamp every day for 20 minutes. Aquarium disinfection is necessary even if there are no visible problems. Preventive measures are the best way to maintain the health of fish and other inhabitants. The next disinfection begins with a disinfecting treatment of all surfaces. The simplest available tools are potassium permanganate and peroxide. Remove from there all the fish and decor, then fill to the edge with 3% peroxide or dark solution of potassium permanganate. Leave everything for 5-6 hours. After that, thoroughly rinse all surfaces and corners.

If so much time to wait there is neither time nor desire, then you can use the express method. Buy a special solution at the pet store that is designed to disinfect all surfaces. Remember to wear gloves before handling. If you have the opportunity to process all formalin, chloramine, hydrochloric acid - then use this option.

To disinfect plants, it is necessary to prepare a penicillin solution in a ratio of 10: 2. Leave all the plants there for about three days.

The most common means are:

  • Isopropane 70%;
  • Ethanol 70%;
  • Saydeks;
  • N-propanol 60%.

These tools can wipe the plants just one time, this will be enough to kill the pathogenic sphere. Sell ​​these funds in pet pharmacies. The rest of the inventory should be boiled. For fidelity, keep them in boiling water for at least 20 minutes. The more time they spend in boiling water, the less chance the bacteria will survive. Note, rubber, plastic and thermometers can not be boiled in any case.

Choose the most convenient way for yourself and enjoy the view of a beautiful, healthy aquarium with happy fish.

How to clean and wash the aquarium: the rules, methods, video examples


In this topic I will try to briefly describe the process of general cleaning of the aquarium world. The point is not tricky !!! But before this event, I think, it would not be superfluous to find out: how to do it correctly, find out how often you need to wash the aquarium, what to wash, sequence of actions, etc.

You need to start a conversation with the fact that there is a big difference between washing an aquarium when it is purchased and a planned cleaning of an already established aquarium or in case of emergency. Therefore, we divide the article into these three components.

Washing and cleaning a new - purchased aquarium

Before you install and populate a new aquarium, you must rinse it out or rinse it out. This is due to the fact that, like any product - the aquarium does not know where it was before the purchase, it is not known who touched it and what happened to it.

For this, we carry an aquarium in the bath. I recommend to prepare a place in advance: prepare clean rags or towels, prepare a surface where you can put a washed aquarium, sponge and soda. The fact is that even a small aquarium is a rather weighty, glass-clumsy thing, and when it becomes wet, then in addition to everything, it also becomes slippery. In this state, the aquarium is not very convenient to turn, raise, carry out other manipulations.

Having prepared everything, put the aquarium in the bath and rinse it, preferably with hot water. We take baking soda and kitchen sponge for washing dishes and carefully but gently wash the aquarium with soda (like jars before seaming).

Well, and then everything should be thoroughly washed several times. If the aquarium allows, then gently turn it over on its side and use a shower spray to flush everything.


After we get the aquarium out of the bath and put it on a previously prepared surface, I recommend using sticks or towels in order to prevent the aquarium from slipping out of my hands. May need the help of a second person.

And now, the aquarium is ready for further installation, which you can read HERE.


- the aquarium can be washed and cleaned with any chemistry: soap, homeostos, comet. However, you should understand that the more "vigorous" the chemistry, the harder it is to wash it. Chemistry residues are not allowed. Since the new aquarium does not need to be thoroughly cleaned, it is not worth washing it in several times and washing it with a variety of cleaning products.

- simultaneously with the new aquarium, wash immediately bought soil and decor. Thus, you facilitate your work. Soil and decor is cleaned with hot water or boiling water. You can add a little liquid soap and rinse with it. At the same time the soaped soil is thoroughly washed !!! It is worth mentioning that in this article, under the ground, I understand quartz, gravel, sand other "colored chips". Special substrates should not be washed.

- if you are the owner of a new large aquarium, then all of the above manipulations are carried out at the installation site. In this case, flush pumped out with a hose, it is better not to use chemistry.

Planned cleaning and washing aquarium

Planned and global cleaning of the aquarium is carried out by experienced aquarists. Perhaps the most important question here is how often do you need to do it? I hasten to happily inform you that often you do not need to completely wash the aquarium. This cleaning is carried out about once every 5 years. This period is strictly individual and depends on the number of fish and plants in the aquarium.

Planned cleaning of the aquarium is carried out more carefully than washing a new aquarium. Such an aquarium is washed with chemistry several times, growths are mechanically removed and shaken off, the aquarium is subjected to heat treatment. After washing such an aquarium, it is advisable to dry for at least a day.

Wash and clean the aquarium in emergency situations - after illness and treatment of fish

Disinfection Aquarium

Unfortunately, it happens that an infection gets into an aquarium. As a result, the fish get sick and need treatment, and the aquarium needs total disinfection.

In such cases, a simple sink will not do. Infectious aquariums are poured daily with disinfectants to the brim. The easiest way to fill the aquarium with bleach or other household disinfectants. Pay attention - DISINFECTING MEANS !!! Not all household chemicals have disinfectant properties, read the instructions for the tool.

Recommend to use: potassium permanganate solution, chloramine solution, formalin solution, bleach solution, hydrochloric or sulfuric acid solution.

When mycobacteriosis is recommended to fill the aquariums with washing powder at the rate of a pound of powder per 30 liters of water.

In addition, the entire aquarium inventory is subjected to heat treatment - boiling.

After disinfection, I also recommend putting the aquarium to dry for at least 24 hours.

Since some people in the "Aquarium Wash" put the concept of weekly cleaning of the aquarium, we will highlight this issue.

Weekly washing and cleaning of the aquarium

When cleaning the aquarium every week, the following procedure should be strictly followed:

1. Get the equipment: filter, aeration, thermostat. Everything is washed, put aside.

2. If necessary, the care and cutting of plants.

3. Clean the walls of the aquarium. Sponge or special scrapers wipers.

4. If necessary, siphon soil. It is not necessary to clean the soil weekly, especially if there are live plants in the aquarium.

5. Only after that the water is replaced: the old water is drained and freshly added is added.

6. Install the equipment back cleaned.

Do not forget to clean the aquarium cover and the lamps from the inside at least once a month.

After all the manipulations, the aquarium is wiped with a dry cloth, stains can be removed with a window cleaner.

Observing the above simple rules the process of washing an aquarium will not be difficult and tedious, and the result will be as efficient as possible.

Aquarium. how to restart the aquarium?

Irish @

It's all over again ... Rinse well, and if you can, boil it. And be sure to stand without fish 10-14 days. You can speed up the process by adding water from a safe, well-established aquarium to the aquarium. Then the time of "aging" will be about 7-10 days.


An aquarium of this type is primarily an underwater garden. For lovers of aquarium flora. Groups of plants are planted very densely, in levels, tiers and there is practically no space left. Fish in such an underwater garden are not the main characters. Usually a flock of neons, small tetras, rarely large fish, but always bright. Be sure to have cleaners - "suckers": antsistrusov or girinohaylusov, sturiossom or others, but not those that feed on plants.
The main criteria for the selection of fish - do not spoil the look and do not harm the plants. Caring for a Dutch aquarium requires not only knowledge and skills, but also perseverance, commitment, patience, and equipment, fertilizers and a wealth of experience. The aquarium was left unattended for a week, and the garden turned into an underwater windbreak. The beauty of the Dutch aquarium is very fragile, demanding and unstable, but the pleasure of contemplating a beautifully made underwater garden is incomparable. Every year in Holland they hold a competition for the design of freshwater aquariums, in which the artistic part is provided by plants alone. There is a whole set of rules and laws, according to which a strict jury draws its verdicts. The beauty of competitive aquariums is extraordinary; it is not even an underwater garden, but rather an underwater paradise.
Despite the fact that not any aquarium can be given the title "Dutch",. You need to be a good professional who knows aquarium plants in order to create decent compositions. Any Aquariums with live plants require additional care and time, so the price for a real “Holland” is higher than for an ordinary aquarium.

Drain, wash and disinfect the soil equipment. Next, lay the soil, fill, install the decor, equipment, connect and wait 2 weeks to establish biological balance, then you can run the fish.

My aquarium after the restart. How it was and how it became.

I will show now only two photos. how it was 01/17/15 and how it became after the restart 4 .03.15.

As it was

Under the cut, these photos are large and small description.

And we planted it in the middle of a lemongrass bush. We did not grow anything that we would not do. Algae and black beard developed. We already could not look at our aquarium. And the algae develop only if higher plants do not dominate. It is 01/17/15, and it was even worse without lemongrass, anobius was covered in a black beard. And in order to put him in a large aquarium, we had to catch an angelfish, they are cichlids and they love lemongrass very much, they devoured their tops and he died. Yes, lemongrass is still planted here, as it is fast-growing, and we really need such plants to suppress the growth of algae. But everything was already going to restart the aquarium, so nothing helped, nothing. The ground sucked in completely, the water change was frequent, but the algae attacked anyway, and many higher plants died or stopped growing at all. The balance in the aquarium was disturbed.

After the restart, which was done on 01/26/15 In general, a month later we became such an aquarium.

How we came to the herbalist to whom we were so eager, I will tell you later and show you by the day how things developed after you bought a bunch of plants. Did a lot for this. This is where CO2 is required, and soil with soil and fertilizers. And fish that are harmless to plants and, of course, an external canister filter. And of course, we continue to do a lot for the beauty of the aquarium. There is nothing like that. We used to have a bunch of plants, I showed you it was not long and everything quickly turned down, there was no proper power and CO (carbon dioxide), as well as an external good filter, as we now canister.

We adore herbal plants and aquariums, so we aspired for what we came to. Of course, it is better to buy the primer from Takashi Amano, perhaps we will come to this in time.

I think many will be interested in the subsequent big release, as it was. How we pulled the moss to the bark, to the stones and the pot. I will show the fish that are harmless to plants and in general I will tell and show everything.
