How to change the water in the aquarium?

In this article we will discuss a fairly simple, but at the same time, a difficult question regarding the change of water in the aquarium. It is simple because there is no need to replace water in the aquarium.

However, there are a lot of nuances and certain specifics that you need to know on this issue. The matter is further complicated by the lack of complete, comprehensive information on the Internet.

As a rule, information about the change of water in an aquarium is either compressed, or one-sided, or only a certain part is covered.

No exception was our site. Here, for example, article Boiled, melted or distilled water for aquarium.

It seems the article is good, but narrow and concise.

So let’s fix this defect. We will consider the question “How to change the water in an aquarium?” As fully as possible and that, in turn, will enable us to make changing water as simple and effective as possible.

For convenience, let’s break down the article into the following sections:

1. WHY DO I NEED TO CHANGE WATER IN THE AQUARIUM, DO I NEED TO DO IT AT ALL?

2. WHY FOR DEFINING AQUARIUM WATER?

3. HOW IS THE CORRECT AND HOW MUCH ON TIME DO I NEED TO LEAVE WATER FOR THE AQUARIUM?

4. WHAT TO DO IF A BIGGER NUMBER OF AQUARIUM WATER IS NECESSARY TO DECLINE? OTHER WAYS OF PREPARING WATER FOR THE AQUARIUM?

5. HOW OFTEN AND IN WHAT VOLUME DO I NEED TO REPLACE AQUARIUM WATER WITH FRESH?

6. THE RIGHT ORDER IS THE PROCESS OF CHANGING AQUARIUM WATER.

WHY DO I NEED TO CHANGE WATER IN THE AQUARIUM, DO I NEED TO DO IT AT ALL?

Many novice aquarists are faced with different opinions about the need to change the aquarium water. Often on the forums or from friends you can hear the phrase: “That I do not change the water at all and …. all OK “or” I rarely, rarely … and also all OK. “

Here that, at the beginner and there is a stupor! How so?

I’ve decorated the entire balcony with buckets, how do I carry a water carrier from the bathroom to the aquarium, but it turns out that this is “monkey labor” !? Without tormenting for a long time, I will answer you – do not listen to these “uncles and aunts”! They mislead you.

AQUARIUM WATER MUST BE CHANGED!

And the thing is this! In the process of vital activity of all aquatic aquatic organisms (inhabitants), the aquarium itself, or rather, the water becomes clogged. For example, an excess of food, fish feces, dead leaves of plants and other organic matter.

All this “dirt” turns into the most terrible poison – ammonia, which is destructive for all living things in an aquarium. Further, nitrifying bacteria that are in the water, the filter and the soil “decompose” ammonia to nitrite (poison), then nitrates (“weak” poison), and then the remains turn into a gaseous state and leave the water.

So, no matter how many useful nitrifying bacteria are in the aquarium of colonies, no matter how many live plants are in the aquarium, which also partially absorb ammonia, no matter how powerful the filters are … no matter, the above poisons tend to accumulate. And you can bring them ONLY REGULAR REPLACEMENT OF WATER TO CLEAN.

What happens in an aquarium for those who do not change the water for a long time? Many aquarium fish tend to adapt and live in the worst conditions – get used to the poisons. However, this function of “survival in any conditions” is not eternal.

In fish, irreversible changes occur in the internal organs, mucous membranes and gills. Fish weaken, their immunity falls.

And the “Doomsday” comes when an outbreak of a bacterial, fungal or infusorian attack occurs … not many survive!

In total, the change of aquarium water is one of the most important ways to maintain “health in the aquarium”, one cannot do without it. Laziness in this matter is a fatal mistake!

WHY DRAIN AQUARIUM WATER?

HOW IS IT CORRECT TO DO IT?

There is such a non-contagious sore in fish, called Gas embolism. In a nutshell – this is the entry of small air bubbles into the blood vessels and blood of fish. As a result, there is a blockage of blood vessels.

Fishes begin to swim sideways, the behavior becomes alarming, fearful. The fins and the whole body begin to tremble convulsively.

The movement of the gill covers slows down, and then completely stops … further death!

A frequent cause of gas emboli is inadequate settled water for an aquarium. The fact is that tap water (tap water) is excessively saturated with air bubbles that are so small that they are not even visible to the human eye.

Just imagine how much water “poured through the pipes” until it reached your tap!

Thus, filling the tap water in an aquarium with fish – YOU ARE VERY RISK. Yes, in practice, everything can do, but this is a game of Russian roulette.

What happens to water, if it is defended? What happens is that small bubbles gradually merge and come out of the water.

Water saturation by air decreases, the risks are reduced to zero.

In addition, it is worth noting that in the process of settling water for the aquarium, heavy and harmful compounds, for example, chlorine as sediment at the bottom of the container and film on the surface of the water, settle.

HOW IS THE CORRECT AND HOW MUCH ON TIME DO I NEED TO LEAVE WATER FOR THE AQUARIUM?

Everything is simple and should not cause much difficulty. The water in the aquarium should settle in a container with a wide neck: a bucket, a basin, an enamel saucepan.

You understand that in a bottle with a narrow neck, excess air goes out poorly. Container for sludge should not be metallic, rusty or made of toxic substances or paints.

Plastic buckets, perhaps the best and easiest option for defending aquarium water.

About the time. The longer the water settles, the better!

I personally defend the water for 7 days – this is convenient and coincides with my Sunday schedule for changing the water in the aquarium. In general, such terms of water settling 1-14 days roam the Internet.

WHAT TO DO IF A LARGE AMOUNT OF WATER IS NECESSARY TO DECLINE? OTHER WAYS OF PREPARING WATER FOR THE AQUARIUM?

But this is really a problematic issue for owners of large aquariums and not large apartments! How to defend 50, and then 100 liters of water?

If this is a new aquarium and the first launch of the aquarium is made, you can immediately fill in the aquarium with tap water, defend it and at the same time add air conditioners to improve the quality of water.

If water is needed for replacement, then our first glance is the only rational option is to purchase construction containers (plastic buckets for mixing mixtures) for 50, 100 liters.

Other ways to prepare aquarium water in the first place include: boiling, freezing water, as well as its purchase of water in the store. See more about this. HERE.

Also, aquarium water can be prepared using special air conditioners such as: Tetra AquaSafe, AMMO-LOC, Sera aqutan and others.

Here is a video about one of them:

HOW OFTEN AND IN WHAT VOLUME DO I NEED TO REPLACE WATER IN THE AQUARIUM?

Almost in all books, on all sites, they write standardly what needs to be changed weekly? part of the water from the total volume of the aquarium. This is a generally accepted norm, BUT NOT DOGMA.

Here, look, please statistics of the survey, which is conducted on our site.

How often do you change the aquarium water to fresh?

As you can see, everyone changes the water in different ways and the weekly replacement of aquarium water is not a dogma! Why? It’s very simple – everyone has different aquariums, different fish, plants, and so on.

For example, there are fish that love the “old” water and the frequent change of water only annoys them (the family of labyrinth fish). The abundance of living plants, also reduces pollution in the aquarium.

In the end, someone has a large aquarium, someone has a small, someone has a big fish, and someone has a small one.

All this individual specificity of the content of fish excludes the concept dogma number and frequency of substitution of aquarium water. And there is only one advice – you should adapt yourself and you should come to the conclusion about how often and how much water you need to change in your aquarium.

In this case, you must take into account the volume of the reservoir, the population of the aquarium, the individual characteristics of the fish, the presence or number of plants, the filter power, the presence of ion exchange resins in the filter, and so on.

THE RIGHT ORDER OF CHANGING AQUARIUM WATER

Finally, I want to give attention to the beginner aquarists, that it is only necessary to change the aquarium water after cleaning the aquarium, and not before.

That is, first we:
– clean the filter and other equipment;
– wipe the walls of the aquarium;
– we thin and cut the plants;
– siphon soil;
– perform other manipulations and permutations;
– and only then we replace part of the water with fresh one;

If you have any questions, any comments on the article, please leave them in the comments – we will discuss.

Replacing the water in the aquarium is an obligatory process for its maintenance. There are partial substitution and complete replacement of water.

Partial substitution in a freshwater aquarium is necessary to maintain the balance of the formed environment due to the fact that it evaporates and changes its composition. However, before changing the water in the aquarium, time should pass from the day of its launch: at least 2 months.

The frequency of partial replacement procedures is once every 1-2 weeks. Replace recommended 1/5 of the total.

Beginner aquarists face the question: how much to defend the water for the aquarium? If tap water does not contain chlorine and phosphates, then it can and not be defended.

Check for the presence of harmful substances necessary tests. If these compounds are in tap water, then you can defend it for day 3. Also, the preparation of water for the aquarium can be carried out using special compositions to change the chemical composition of the water.

With a sufficiently large volume of the aquarium (more than 150 liters) without special preparation, you can replace up to 20% of water in it.

Deciding what kind of water is needed for an aquarium when carrying out a partial substitution, should be guided by the capriciousness of the species of fish and plants that inhabit it.

Substitution implies a weekly replacement of the third, fourth, or fifth of fresh water, preferably settled. To prevent the fish from getting shock, it is recommended not to allow a large temperature drop, which may adversely affect the health and behavior of residents. Some aquarists change the water in small portions, pouring it directly from the tap.

Most often, this method is practiced by owners of large aquariums, adapting to their pets and having a normal liquid performance.

Complete replacement of water in an aquarium is extremely undesirable, so it should be carried out only according to a special need – for example, if the aquarium needs to be repaired or disinfected.

In order to drain all the water, prepare a bailout, where you need to catch all the fish – it will become a temporary aquarium for them. If there is no spare aquarium, you can use a bucket or basin.

In case there are a lot of small fish, make them the right aeration.

If possible, all plants are also removed from the aquarium. If the reason for the complete replacement lies in plant diseases, then they need to be disposed of, and after changing the water, plant others.

Once you have removed all the fish and plants, you can begin to drain the aquarium. Take a bucket or basin, which will pour water, bring it to the aquarium.

To complete the replacement of water in the aquarium, first drain all the old water with a hose into a basin or bucket.

As soon as the aquarium is empty, it must be washed, sanitized and dried, and then filled with new water. Remember that after that the ecosystem should be normalized and the balance should be adjusted, therefore in the first 2-3 days a bacterial outbreak will occur, which will pass by itself.

The water will grow cloudy, but as soon as it becomes transparent again, you can plant the plants, and it is better to start the fish in 7-9 days.

Remember that to abuse the full replacement of water is not worth it. If, for example, one fish died, this is not a reason for panic; if several of them are sick, then they need to be transplanted and tried to cure; and only if there is an outbreak of any infection, and drugs do not help, then you need to change the ecological environment, that is, water.

Replacing the water in an aquarium is sometimes considered the most effective tool in the fight against bacteria, because they do not react to drugs due to their protective mechanism. But still, before changing the water, think more than once – this is a huge stress for fish.

To change the water in the aquarium, instead of a hose, you can use a vacuum or electric pump. The simplest device is a siphon, which consists of a narrow tube and a cylinder.

With its help you can clean the bottom and walls of the aquarium from the plaque and food debris.

Electric pumps have recently become quite popular, but they are used to pump water from small containers, and in other cases it is better to use a regular siphon.

❶ How to change the water in the aquarium fish :: how to change the water in the aquarium with fish :: Care and education

The quality of water directly affects the health of fish and other inhabitants of the aquarium. You need to change it several times a month, each time topping up a small part.

Water from the tap must be defended, and only after that it can be planted algae and underwater plants, as well as run your pets.

The question “How does a little girl retrain to go to the tray (she is 4 months old)? “- 3 answers

  • -water tank;
  • -siphon nozzle or plastic tube with a diameter of 1-1.5 centimeters;
  • -additives to neutralize harmful substances (optional).

1. Get the right amount of water and defend it for at least 5-7 days. In the event that time is tight, after 1-2 days, filter the water through activated charcoal or boil for 10 minutes. However, you must remember that in the process of boiling water loses oxygen and it must be aerated.

Defend water only in an enamel or glass container (the enamel must be intact). It is undesirable, but still you can use plastic bottles to stand on them.

Put the water in a place where the sun will not fall on it.

2. If there is soil in your tank, drain off some of the old water using a special siphon nozzle. Otherwise, you can also use a plastic tube of small diameter (1-1.5 centimeters).

At the end of the tube, dipped into the water, be sure to wear gauze so that the fish do not suck into it. Do not forget about the walls of the aquarium, if they are very dirty, you must clean them before changing the water.

Water replenishment is carried out only partially, at a time you can change no more than 1 / 3-1 / 5 of the volume of the aquarium. You should carry out a complete change of water only in extreme cases, such as: the appearance of fungal mucus, entry of unwanted microorganisms, high soil contamination, etc.

3. To fill the aquarium, defend the water for at least 5 days, then pour the prepared it into the aquarium, plant the plants and run the fish. If you want to speed up the establishment of a normal environment, add a little water and soil to it from an already established, safe aquarium in which there is a ready-made complex of microorganisms.

If desired, you can purchase special supplements that neutralize harmful substances in the store; you will not need to defend water when using them.

Do not overfeed the fish, it is the erroneous feeding that often causes damage to the environment in the aquarium.

In order to check whether the water in the aquarium is good or not, inhale some air from its surface. The smell should be light and unobtrusive.

Odor impurities indicate that adverse processes are occurring in the aquarium. It is best to refill water once a week.
