How To Change The Water In The Aquarium

One of the keys to successful home fish farming is maintaining the water in an aquarium with fish in constant composition. Biological balance in the amount of organic compounds in the structure of water can be achieved thanks to its filtration and systematic renewal. The health of the fish and the well-being of the mini-ecosystem of the home aquarium directly depend on the observance of all the rules during the last procedure.

Is it possible to completely change the water in the aquarium

During the life of absolutely all aquatic inhabitants, the aquarium environment is polluted by fodder surplus, fish excreta, dead leaves of plants and other organic matter. This means that it is necessary to change and purify the water in the aquarium, but this must be done very carefully, following certain rules.

First of all, it should be said that there are two types of updating a home aquarium: partial (incomplete) replacement and absolute replacement of water. The first type of water renewal in a freshwater artificial reservoir maintains an equilibrium of the biological components of the aquatic environment, despite the constantly changing structure of the fluid.

Thus, in case of a disease of one or several inhabitants of a water reservoir, they can be moved to quarantine in another container, but if the disease has spread to all, the old water should be drained and replenished with a new aquarium.

Absolute replacement is often a necessary measure, since pathogenic microbacteria multiply very quickly, making water unsuitable for living organisms.

A full water update is also carried out with a planned restart of the aquarium, that is, if necessary, a drastic reduction in the level of organic compounds accumulated in the liquid.

How often do you need to update the water

Depending on the volume, aquariums are often divided into small and large. The first type includes tanks with a total displacement of 5 to 50 liters, and the second. glass containers from 50 to 100 liters. The smaller the aquarium, the more often it is necessary to change the water and carry out cleaning.

A water update in the amount of 1/5 of the liquid of the total volume will naturally affect the balance of the biosphere, but after a couple of days the recovery process will occur. The rate at which equilibrium is acquired depends on the size of the aquarium: the larger it is, the faster it will happen.

A half water change will disturb the stability of the aqua sphere, with some inhabitants (both fish and algae) having the risk of dying. In this case, the process of normalizing biospace will take several weeks. Absolute water renewal will completely destroy the habitat and you will face the task of starting the aquarium from scratch.

How to change the water in the aquarium

The main task of a novice aquarist is to learn how to maintain a healthy state not only of the individual inhabitants of the reservoir, but also of the entire aquifer.

That is why it should be borne in mind that the aquarium life activity is divided into 4 stages according to the level of formation of biological equilibrium:

  • new (fish and plants just launched and planted);
  • young (2 months after launch);
  • mature (semi-annual "age" of water);
  • old (one year after the first launch).

A phased breakdown is done for the reason that each of these stages has its own rules and methods for replacing water in the reservoir. The water space in the new aquarium is rather unstable, which is why to establish a certain biological regime and balance one should refrain from invading aquarium life during the first two months.

After 60–90 days, you can proceed to a water change of 20 percent of the total volume of the aquarium. It is necessary to carry out this procedure once in 14 or even 30 days. If you have such an opportunity, the ideal option would be a 10 percent water recovery once a week.

It must be said that for the inhabitants of an artificial reservoir this does not matter much, however, to prolong the period of maturity and go to the stage of a young aquarium, these actions are simply necessary.

How To Change The Water In The Aquarium

At the initial stage, the aquarium aquatic environment will come to a certain degree to equilibrium, and the full establishment of a biological balance will fall on a 150-day period from the day of launch. The maturity of the aquarium comes after 6 months from the moment of its first launch.

At this stage, it is very difficult to disturb the biological balance in the reservoir. At this stage, a partial replacement of water is used in the amount of the same 20% of the total volume, but already with a one-time monthly frequency of completion and mandatory ground revision and surface cleaning of glasses.

After a year of residence of the fish in the aquarium, the liquid sphere begins to age. For the return of youth and the improvement of the aquatic environment, the interval between renewals should be increased to such an extent that water renovation takes place in the same volume, but every 14, not 30 days.

How To Change The Water In The Aquarium

Perform these actions must be for two months after the aquarium reaches the old age. Thus, avoiding the global cleaning of the reservoir, which can be life-threatening for pets, you will warn the degradation of the aquasphere and return it to its former youth.

Due to improper substitution of water, and, more precisely, its unsatisfactory condition, fish are exposed to a disease such as a gas embolism (air accumulation in the tissues and vessels of aquatic vertebrates).

The tap liquid is excessively saturated with small bubbles that are invisible to the naked human eye, which is why before pouring such water into the aquarium, it must first be defended. The most suitable container for settling is a bucket or a basin made of plastic, since products made of zinc, aluminum and other metals, especially the rusty ones, will poison the water.

The enameled pan is also safe for this purpose. The process of settling must be carried out for at least 3-4 days, while avoiding contact with the container of direct sunlight.

Partially (water change)

For a partial water upgrade, you will need:

  • tank for pumped liquid (you can take the usual bucket);
  • scapula or glass scraper;
  • hose, preferably transparent, with a special siphon nozzle.

The last tool (hose) should not be made of rubber, as products from this material can release substances that adversely affect the livelihoods of aquarium dwellers (both fish and plants).

Then one of the ends of the hose (the one on which the siphon is attached) you need to lower into the aquarium, and through the second, gently and quickly suck in your lips with air, after which you sharply lower the hose into the bucket.

If this method is unpleasant for you and you are afraid to take a sip of water, then the following method will be optimal: the whole hose is lowered into the aquarium, both ends are clamped with your fingers, after which one of them is sent to the water extraction bucket, and the second is fed to the aqua-ground, accumulations of dirt and residues of uneaten food.

Following these actions, it is necessary to release both ends of the hose and drive it with a siphon nozzle along the bottom, as well as at the corners of the tank, pumping out water and pollution. Thus, the tube to replace the water blows the bottom of the aquarium, clearing it, after which the walls of the glass tank are washed with a special liquid, the purpose of which is to remove the pathogen plaque.

By the way, for laying out the soil to the aquarium it is better to take stones, not sand, since the latter can clog the hose when cleaning the tank. For the success of the procedure, you must accurately guess the size of the tube: length and diameter.

The first indicator should not be large and in each case is individual, but its length should be enough for one end to sink to the bottom of the aquarium, and the other for the edge of the bucket, which is located very close to the tank. The rate of the second indicator should be not less than 10 and not more than 15 mm.

Too long and wide hose can cause excessive pumping of water, as well as sucking the equipment of some fish. In the absence of a special siphon equipment, for greater convenience of pumping fluid, you can use a funnel or wrap gauze on that end of the tube, which is lowered into the tank.

For aquarium cleaning and partial water changes, the volume of pumped out liquid should be no more than a third part, in the extreme case. half of the total mass.

Full replacement

If you are faced with the troubles mentioned in the first paragraph of the article, and are forced to make an absolute water upgrade, then you must first get all the fish from the aquarium, as well as snails, if they also exist, and arrange for them a different habitat for a while.

After that, thoroughly drain the old liquid, and thoroughly clean the soil, algae and aquarium decorations. Do not forget about the need to disinfect the walls of the tank.

Only after all the above actions have been done, can we pour in new (pre-settled) water, spread the soil, carefully plant the plants, set the scenery, and only a week later run the fish.

What distinguishes the replacement of water in large and small aquariums

The main difference between a water upgrade in a large aquarium and a replacement in a small tank is that in the latter it is much easier to do this, but it is also necessary to perform this action due to the smaller volumes more often.

Thus, given the frequent discussions around the issue of the frequency and feasibility of replacing water in an aquarium, we can conclude: frequent water renewal may be a factor preceding the disease and death of fish.

For each aquarist, the most appropriate solution to the issue of akvazameny will be an orientation to the dimensional characteristics of the household tank and other individual factors indicated in this article.
