BRIEF INSTRUCTIONS AQUARIUM INSTALLATION
By purchasing the first aquarium and creating your underwater kingdom, you unwittingly touched by the mistakes made, incidents and incidents.
What I lacked at that stage was step-by-step brief instructions. After all, I simply did not want to read a whole book or a bunch of Internet articles about the first launch of an aquarium, because there was one “zombie thought” in my head – tomorrow the aquarium should earn!
I HOPE THIS INSTRUCTIONS WILL BE USEFUL FOR YOU, UNDERSTANDING SPEED AND GIVE STEP-BY-STEP ANSWERS TO YOUR QUESTIONS: HOW TO BUY AN AQUARIUM? I WANT AQUARIUM WITH WHAT TO BEGIN?
HOW TO RUN THE AQUARIUM?
OK, GET ON …
1. Determine where the aquarium will stand?
– it is better to place the aquarium in a dark corner so that direct sunlight does not fall on it (from them in the aquarium you can get algae uncontrollable, sunlight creates glare on the glass).
– consider how the power supply will be suitable for the aquarium (for connecting: lighting, filter, aeration, heater).
– if you decide to put the aquarium is not special. stand, but on the furniture you already have, or you want to build an aquarium in a furniture niche – be sure to consider the weight of the aquarium with water so that it does not fall under its weight. The surface must be durable.
– If you have small children, think about their safety and the safety of aquarium inhabitants from children. Children’s access to the aquarium and its equipment should be limited (the principle – “look, but don’t touch”).
2. Pre-dial tap water for sludge.
– this should be done at least a day before landing the fish. The presence of dissolved oxygen in tap water can kill fish.
Although in practice everything can do, especially if you use special tools to improve the composition of the water (for example, Aquaceave from the Tetra series). But it is better not to risk, especially for the first time.
Remember, an aquarium for beginners – the first launch of an aquarium should be carried out “according to a template”, later being experienced you can experiment, for example, if the volume of the aquarium is large and there is no place to defend the water, you can fill the installed aquarium with tap water and defend it, at least 1 day. With this method, need / desirable “Aquaseiv.”
3. Now we run to the pet store and:
– buy a pre-looked aquarium (corresponding to the selected location).
– filter and aeration (must correspond to the volume of the aquarium).
– choose the soil and decor (artificial plants, stones, castles, snags, etc.).
– if it’s winter, you still need an aqua heater.
4. We proceed to the step-by-step installation of the aquarium:
– level the surface special furniture or furniture on which there will be an aquarium. To do this, buy the simplest water building level ($ 3 – then it will still come in handy on the farm).
The fact is that aquarium water creates pressure on the walls of the aquarium. And any even a small angle of inclination creates a very tangible pressure on a separate wall (the pressure will not be uniform). From what the aquarium can “burst”.
Level the surface as carefully as possible. Only small deviations are allowed.
For small aquariums – up to 35 litas, leveling the surface is not necessary.
– we establish an aquarium on a surface. A polyethylene bubble pad (usually sold with an aquarium) is laid between the aquarium and the surface.
Ensure that the edges of the aquarium do not hang from the pedestal or furniture.
– now pour out and distribute the soil in the aquarium. It is advisable to wash it in advance after the pet store, thereby getting rid of excess dust and dirt.
– set the decor.
5. Fill the aquarium with separated water.
Not an easy job I can tell you, especially if the volume of the aquarium from 100l. (10 buckets).
Water is poured gently / slowly.
In order not to wash away the soil and not to scatter the scenery, I recommend to put some dishes or a can on the bottom. Directing a stream of water on the can, the water will spray and your decor and the soil will remain intact.
Fill the aquarium up to the top leaving, approximately, 5-7 cm from the edge.
6. Install filtering and aeration, run.
7. Now we run to the pet store again and buy long-awaited fish, snails, live plants … don’t forget to buy food (preferably wait at least seven days with this, the water should at least “infuse”, aquarium chemistry accelerates this process: AquaSafe, Baktozim , Tetra NitratMinus Perls other).
8. Release the fish in your tank. The package with the fish is lowered first into the aquarium water, a little scooped into the package of water and kept in the aquarium for about 15 minutes (for adaptation).
Then turn the bag over and release the fish.
In the future, all you need is attention and care for your pets.
And with them will gradually come experience!

Starting the aquarium from scratch: step-by-step instructions for creating a new aquarium
LAUNCH OF AQUARIUM
The launch of the aquarium is the most important starting point in the life of the aquarium world! That is why, this issue should be given maximum attention. Due to the fact that Forum FanFishka.ru users regularly ask questions about the proper start of the aquarium, about the first month of its life, it became necessary to supplement this article with this preface, the goal of which is to put the aquarium beginner all in a simple and understandable way and to give a basis for understanding the essence of the aquarium.
The first thing you should pay attention to is that we all have different aquariums: in terms of parameters, in aquatic organisms, etc. In this connection, it is simply not possible to display the standard of launch and further care of the aquarium.
Each “bank” has its own specifics, its own nuances. From this, it is possible to make an important conclusion – before doing something, a novice aquarist should independently read, study information on the specificity of the content of certain aquatic organisms, a beginner should thirstyly absorb information about the nuances of the content of his aquarium.
Without this, nowhere! As they say, you will not help yourself, no one will help you!
A common misconception of people is their understanding of the essence of an aquarium – like a certain can of water and fish. Far from it! An aquarium is not only water, fish and aquarium plants.
This is a whole microcosm – an almost closed biological system, in which, as in nature, everything is interconnected. It should be understood that the aquarium is a collection of hydrobiotic, i.e. of all living aquarium organisms and these are not only fish and plants, they are also mollusks, crustaceans, algae, protozoa, bacteria and fungi.
Can say that The aquarium as such is a compound organism consisting of a chain of “living links”!
From this we can draw another important conclusion that the primary task of an aquarist is to establish a well-coordinated work of all links in the chain. You can often hear the expressions: “aquarium balance”, “biological balance”, “healthy aquarium”, “correct aquarium”, etc. – in essence, this means that the aquarium works like a clockwork, where all the gears are in place and perform their function.
Also, it should be understood that the aquarium is a complex mechanism. The processes that take place in it are complex and diverse. A frequent delusion of a newbie is the thought that: “Here I’ll throw a pill right now, which I’m recommended and everything will pass,” no … no … no and no again!
There are no magic pills. All aquarium hydrochemistry only makes life easier for an aquarist, but is not the key to success.
For a deeper understanding, here are some examples of some processes (chains) that take place in an aquarium.
Example number 1. The so-called “Nitrogen cycle”
Fish waste and dead organic matter (hereinafter referred to as “PJ”) are regularly released into the water.
Under the action of beneficial bacteria – nitrifying, PJ breaks up into poisons:
first ammonia / ammonium (NH3 / NH4),
then nitrites (NO2),
then nitrates (NO3),
and then, by bacteria denitrifiers, nitrates decompose to a gaseous state and are removed from the aquarium.
Example number 2 “Nitrogen cycle with plants”
PJ, regularly fall into the water.
Under the action of beneficial bacteria – nitrifying, PJ breaks up into poisons:
NO3 nitrates (or more precisely nitrogen N) are fertilizer for aquarium plants and are used by them in the process of photosynthesis.
If the process of photosynthesis is adjusted (there is a proper amount of refreshment, CO2 and other fertilizers in the aquarium), the plants “pull out nitrates” take nitrogen (N) and release water H2O and oxygen (О2), which is very useful for aquatic organisms and in general for oxidation processes.
Example number 3 “Negative”
PJ, regularly fall into the water. And in the aquarium there are not enough good bacteria, no plants.
The concentration of poisons accumulates, deadly for all living things.
Aquarium, as a holistic organism “Sits and thinks what should I do? How can I reduce the concentration of poisons … and here he recalls algae disputes, which are always in a state of depression in aquarium water ”
There is an “algal flash” – the aquarium is covered with the lower plant world: green, brown, black algae.
Due to the algae, the aquarium is trying to get rid of harmful substances.
Well, and then, if you don’t remember it in time … the aquarium is overgrown with “greenery”, goes out, turns sour and dies!
You can continue to continue to give examples of the relationship of individual elements of the aquarium chain. A lot of them!
But I think the essence is clear. Additionally, see the material: MUTT AQUARIUM, Nitrates and nitrites in an aquarium.
And here we come to the main task of this article – to the question, how can an aquarist help his family aquarium, at the start and the first month of life?
The most important thing that a happy owner of a new aquarium should understand is that in a young aquarium there is no bioblans at all – that is, in fact, nothing works: there is no proper amount of bacteria, fungi, freshly planted plants have not yet become stronger, etc. … while the fish are already giving out PJ, some leaves of the plants die off, the remnants of the uneaten food are decomposed …
In this connection, below I will cite a set of rules for the care of an aquarium in the first month:
one. As a general rule, in the first month of fish in the aquarium, for obvious reasons, should not be.
Often, newbies ask … well, you can, well, you can already plant a fish))) By myself I know, this is a heel-burning desire to have the first fish! Therefore, I will answer this way – it is possible, but carefully))) … it is desirable to at least wait two weeks … well, at least a week))) At the same time, it is necessary to start populating the aquarium with fish gradually, starting with the most stoic and undemanding. Which often are catfish like fish (for example, Corridors, Ancistrus).
Well, then, if everything is normal, you can already look at and sit down “the main characters of your aquarium theater.”
Often in the vastness of Runet, you can find opinions and statements such as: “You think, I immediately put the fish in the aquarium and everyone is alive!” I note that this attitude is not permissible. Why?
The answer will be given by this visual table about the growing concentration of poisons in the first month of aquarium life.
From this table it is clear that toxic substances simply “climb up” and go off scale, because there are no bacteria, no balance. And now imagine, you bring the first cabin from the pet store!
I note that in most pet stores fish are in poor conditions, and therefore, the health of most of them is not the best. So, from transplantation and transportation of your fish, in addition, stress, here it is still being planted in a new aquarium with other parameters of water, and besides, in water, the concentration of ammonia, nitrite and nitrate is high. What happens to the fish.
A fish with a strong immunity will “tolerate” and it can all go well, a fish with weak immunity will get sick and will need to be treated, the treatment will negatively affect the condition of the aquarium as a whole and complicate the life of the aquarist several times, well, glue together flippers. ”
2 In the first month of the life of the aquarium they try not to bother! What does it mean?
This means: you do not need to constantly climb into it, you do not need to do the cleaning, change the water, or siphon the aquarium floor! Yes Yes Yes.
Exactly. It would seem that if we clean everything thoroughly, siphon and rub everything, then there will be no PJ, and therefore no problems!
But, unfortunately, with these actions we only prevent useful microorganisms from developing.
For example, in water only, only a colony of beneficial bacteria has formed, only a favorable environment has been formed, and we have to change the water again and fill in fresh “empty” water! Or, for example, the bottom of an aquarium … after all, in essence, this is a biological filter – “a house where 90% of our beneficial bacteria live” … for the first, second week, they just started to “occupy a new place”, and we siphon them suck out of the house.
Of course, the above is not a dogma, but as a general rule, it is recommended not to clean the aquarium (and all its equipment) during the first month. Thus, we give the opportunity to the aquarium, which is called “insist”.
3 Since water is not sterile, sooner or later the aquarium will independently “fill” with invisible to the human eye organisms. Nevertheless, it is possible and even necessary to use aquarium hydrochemistry, which helps the aquarium to gain bio-balance.
it Tera safestart and Tetra aquasafe, and Tetra bactozym, and Tetra NitratMinus, Tetra NitrateMinus Pearls, Sulfur nitrivek, zeolite and many, many other analogues, about which you can read the full information on the pages of our site. The essence of their action is simple:
– some drugs “ennoble water”, that is, they make water suitable for aquatic organisms (AquaSafe) and contribute to their reproduction of beneficial bacteria (Bacti).
– others are ready-made concentrate, the most beneficial bacteria that fight poisons (Tetra SafeStart, Sera Nitrivek).
– either at a biological or chemical level, the concentration of poisons is reduced (Zeolite, Sulfur Toksivek, Tetra Nitrate Minus).
All these drugs can be used both individually and together. THE NOTE: In a pet shop or with friends of aquarists, you can ask for a squeeze from a filter that worked in a healthy aquarium. This squeeze – brown slurry contains a huge number of beneficial bacteria, i.e. essentially replaces starter drugs.
You just need to pour it into your aquarium for three hours after squeezing.
1. It is important not only to install the aquarium correctly and connect everything, this is only half the battle.
2. It is necessary, as thoroughly as possible, to understand and understand that an aquarium is a complete organism, a closed corner of nature in your home, and not just a vessel with fish.
3. Aquarium is not a picture, set and forgotten. It requires attention, patience and perseverance. It is necessary to read, learn and try to improve your aquarium – this is the beauty of aquarism.
You need to learn to see the “aquarium on the eye,” you need to learn to “feel it.”
4. At the same time, you should always follow the golden rule – the aquarium does not like sudden movements. Everything needs to be done with the mind, gradually and not from the bay-floundering!

And also, the curious story of our forum member Iren2321, about his impressions when launching the first aquarium
Preliminary preparation before the acquisition of small fish
If you have never had an aquarium and no experience of keeping fish, then it is best to start fish that need minimal care and are not very demanding to the conditions of existence. This will avoid the death of your fish, as well as gain experience and knowledge in the content of the aquarium.
Many tropical fish require the maintenance of a certain water quality (hardness, acidity, temperature, etc.), the presence or absence of plants, a certain brightness of the light or its absence.
For unpretentious fish, the range of comfortable conditions is much wider, which allows them to be kept in a lower quality environment. They are also less susceptible to negative factors (improper feeding, delayed water changes, etc.).
There are several determining factors when choosing a fish:
- aquarium size;
- selection and compatibility of different types of fish;
- the size and temperament of the fish.
If you already have an aquarium, you need to determine what and how many fish you can fit into it. This will avoid overpopulation, which leads to unnecessary fights, oxygen starvation, eating predators of peace-loving fish.
Important parameters for species compatibility are their size and temperament. Of course, it is impossible to contain predators and herbivores in one aquarium, otherwise the latter will become food.
In the wild, larger fish eat smaller ones.
Even if you only have herbivorous fish, you need to check that the size of the smallest fish is larger than the largest mouth opening of the fish in the aquarium. This will avoid unnecessary casualties.
Certain fish are territorial and do not let other species close to their habitat. There can be many reasons:
- suitable food supply,
- the spawning ground arrangement (the couple who carry out the treasure jealously guard the nest),
- the presence of water turbulence with optimal temperature parameters, etc.
Differences in species manifested in modes and methods of feeding. For example, somobraznye eat food from the bottom, petsliiliformnye – from the surface.
Some kind of fast and agile, and some – slow and unhurried. Fish require different food, and if you do not like it, it is better to choose pets with the same way of feeding.
If you do not follow the feeding regime, then some species will be hungry and others will be overfed, which will lead to a reduction in the life span of all inhabitants.
Often, fish are acquired that have not reached puberty, which leads to incorrect judgments about their temperament. Therefore, in order to fully determine whether this fish suits you, it must grow and be in comfortable conditions.
Of course, if any representative is unnaturally pugnacious, cuts off fins or clogs other fish, it should be isolated.
This topic is hot and is discussed in many forums. There are many types of fish that require minimal maintenance.
This allows you to choose the most suitable pets for each novice aquarist both in a variety of colors and in size. The aquarium can be equipped with beautiful relief and plants, and originality will give a contrast to the color of the fish.
Very often, beginners choose viviparous fish such as swordtails, plazii, guppies, mollies, etc. And this is an excellent choice.
They have a good survival rate, are easy to maintain, are active, have a long lifespan and do not require strict conditions of detention.
There are some types that are ideal for beginners.
Guppy – fishes of the Petsiliev family, with a peace-loving character, calm and unhurried in behavior. Coloring is very diverse and beautiful. To the composition of the water does not impose requirements.
Periodically you need to change the water. Viviparous
Easily distinguished by sex. Males are much smaller, more beautiful and brighter. Omnivores.
Overfeeding is not recommended. Easily tolerate a decrease in water temperature to 15 ° C.
Swordtails – Family Peziliye. Have more than 25 decorative varieties. In the male, the tail fin has the shape of a sword.
Very beautiful fish that does not require special conditions and specific size of the aquarium. Viviparous, easily reproduce.
When the fry appear, the parents should be moved to a free container to avoid eating the children.
Gourami – mobile fish, differing in an interesting spotty color, are curious. To other species of fish and inhabitants are tolerant. They can breathe not only air dissolved in water, but also oxygen directly on the surface.
Somics different external originality. Unpretentious, peaceful, eat any food from the bottom.
Clean up the remnants of food uneaten by other inhabitants. Orderlies aquarium.
Prefer bottom-living and easy to get along with other species.
Neon – Representatives of the Kharatsin, there are more than 150 species of fish. The most common among beginners are red and blue. The content is simple, undemanding to water.
They love the space, the length of the aquarium should be at least 50 cm. Excellent jumpers, so you need to cover the surface of the water with glass or a lid.
Danio – schooling, bright, beautiful fish. Aquarium is needed with a length of at least 55 cm. Very mobile and like space.
Requires regular water changes and good aeration. Great jumpers, so you need an aquarium with a lid or glass.
Prefer good lighting and clear, clean water.
Barbusses – schooling fish. There is a huge variety of species (more than 200).
In the schooling content of peace. Very active.
It is not recommended to keep them with fish, the tail of which has thread-like or voile forms. They love floating plants.
gold fish – representative of the carp family. It is very popular, but it requires a large volume of aquarium (per adult of at least 35 liters of water). Prefers clear, clean water and requires its regular substitution.
Very voracious, so you need to be careful with feeding. Prone to overeating.
Antsitrus – somobrazny, herbivore. Very good orderly, nibbles small shoots from the glasses of the aquarium.
The oral opening resembles a suction cup. Males have a large number of mustache.
Peaceful. It is recommended to feed tabletized plant spirulina.
Presents the most common, unpretentious, do not require special care fish that are suitable for beginners. But this does not mean that they do not need to be watched, to know their preferences, the temperature of the water, etc.
Before we talk about the rules of care for an aquarium, it is useful to understand what it is for. Most people keep it for beauty. Many have a rest, admiring the change of pictures behind the glass bank.
Someone keeps him in the apartment to humidify the air. Just listed is enough for the aquarium to take place in our home.
The main thing, probably, lies in the fact that caring for an aquarium opens up for many children the path to knowledge in science, where fish faithfully serve medicine, biology, and fisheries. An experienced aquarist will always find application in this industry.
It is also very important that the aquarium is a model of the terrestrial biosphere. So, in your house decided to start fish. Where to start?
With a choice of aquarium, of course. They are glass, prefabricated (metal frame, glass walls) and plastic.
The first are good because they are always at hand: any jar can be turned into an aquarium. It is better to take rectangular cans. Round and spherical distort the shape of its inhabitants.
In addition, glass aquariums have a small volume. They can not show all the variety of colors of the water world because of the relatively small number of inhabitants, which is provided by larger prefabricated aquariums.
But do not strive to acquire a very large aquarium – more than 10 buckets. In the event of a leak, you can flood your own and neighboring housing. It is accepted to divide prefabricated aquariums into very thin – “pictures”, a little thicker – “screens” and usual ones with a ratio of width to depth approximately one to one, and two to one lengths to them.
Plastic aquariums for the constant maintenance of fish are uncomfortable: plastic quickly loses its transparency. They are only good for transporting fish.
Choosing an aquarium, do not forget to get the necessary equipment: nets, a rubber hose for making siphons, a water thermometer, a basin, a bucket, banks of different sizes for storing feed and temporary keeping of fish, a reflector for lighting and heating water with a lamp not exceeding 10 watts for every 10 liters of volume. To hurry with the acquisition of more complex equipment: thermostats, filters, aerators – novice aquarist should not.
Over time, having gained experience and knowledge, everyone will decide how much, when and what new devices and automatons should be installed.
At home, you need to choose a place for an aquarium, then proceed to the preparatory work on its settlement with plants, clams and fish. First of all, check whether the acquired or made aquarium is flowing. Fill it with tap water to the brim.
If everything is in order, you can do the washing of the aquarium. Putty and glass in a new fish house may contain harmful substances. They are removed during the week, daily replacing tap water.
Water from local water bodies can only be used after pasteurization: two to three times heating to 80–90 degrees, in order not to introduce pathogens or parasites into the aquarium. Last time, wash it with soap and rinse well.
The next stage is laying the ground. It is made of well-washed sand or pebbles.
The soil should be 4 to 5 centimeters thick. Pebbles can be put on its surface, better dark, to create a resemblance to a natural bottom.
Now you can purchase plants. They are bottom and floating on the surface or in the water column. First landing is best done before filling the aquarium with water.
Large dark green plants should be planted in the corners and along the back wall, light – in its center, and along the front glass – plants with beautiful patterned leaves. When planting it is important to ensure that the roots in the ground are properly located.
After planting is completed, the aquarium is filled with settling tap water. She is defended for five days to get rid of chlorine.
A few days later, when the bottom plants take root, you can put floating species into the aquarium and start up clams.
By this time, the aquarium comes to life. It forms the complex world of bacteria, the smallest algae, fungi and protozoa. Plants, releasing oxygen into the water, created favorable conditions for them.
Such an aquarium is ready to meet fish or other large aquatic animals. Aquarists contain not only fish, they have shrimps, turtles and other exotic inhabitants of the waters.
Those who take the first steps in the creation of an aquarium should begin with the most undemanding inhabitants: with cold-water goldfish or some viviparous, such as guppies.
Novice aquarists often do not know the rules for selecting fish for living together. Remember that you should not keep together cold-water and warm-water fish, predatory and peaceful, large and very small.
The density of the inhabitants of the aquarium should be optimal. When determining it, we recommend focusing on the following indicators.
When keeping cold-water fish and very large heat-loving ones, take two liters of water for every centimeter of body length. The rest of the fish need to allocate at least a liter.
What is a healthy aquarium? This is clear water, bright greens, joyful behavior of the fish.
He over the years does not need a complete change of water. In cold-water fish (they are big muddy) need to be cleaned once a week. In warm-water – once or twice a month.
Cleaning begins with cleaning the glass of bacterial algal plaque. Then remove dead and excess plant sprigs (in the event that there are too many).
In a well-lit aquarium, they can take up to half the volume of water. After completing these operations, siphon is removed from the bottom of the sludge, dirt, remnants of food.
Purify water is added to a clean aquarium to the level of the previous level.
For warm-water fish, the constancy of the temperature regime is very important: temperature fluctuations during the day should not be allowed more than one degree. Although, of course, you can gradually accustom these fish to life at unusual temperatures (16 – 18 degrees), but it is still better to maintain 23 – 26 degrees in an aquarium – their living conditions in their native waters.
Very important for the normal health of pets has them proper feeding. Feed the fish should be once or twice a day.
Leftovers after 10 – 15 minutes must be removed. They pollute the environment and contribute to the appearance of putrefactive bacteria in the aquarium. If there are signs of deterioration of water, it is necessary to make a thorough cleaning, replacing up to half the volume of water in the aquarium.
If this does not help, catch fish, take out plants, rinse both them and the ground. In short, start over.
For feeding use dry, live, granulated factory feed. Try to feed the fish last, gradually adding live food.
Best of all, he was homemade.
