Today, in order to change the water in the aquarium, you must first carefully prepare. Here it should be noted that preparation of water for the aquarium – this is a very important job, the implementation of which must be taken very seriously. After all, the use of conventional running water without prior preparation, can lead to extremely negative consequences. Let’s look at this issue in more detail.
Why do you need to defend the water?
The main reason for this is harmful impurities that can harm the inhabitants of our aquarium. After settling, solids sometimes appear in the sediment. Initially clear water after a while can grow turbid.
Many aquarists leave the water for substitution to breathe for a few days, and so that all harmful suspensions evaporate for a week. This assumption is partly true, but it cannot guarantee the quality of the prepared water.
Before we do something, we always know why we need to do it. By keeping tap water outside the pipeline, we are trying to improve its performance so that it does not harm our fish. In other words, when defending water, we get rid of most of the malicious components.
Conditionally harmful substances in the water can be divided into:
- solid (precipitates to the bottom);
- gaseous (volatilized from water to the environment);
- liquid (initially dissolved and remaining in water).
The process of settling can affect only solid and gaseous mixtures, and it does not affect liquid substances in any way.
What should be the temperature of the water in the aquarium?
Water temperature for the aquarium plays a crucial role. It depends on the health and ability of fish to breed. For each species of fish, a completely different water temperature is suitable. Conventionally, all the inhabitants of the aquarium can be divided into heat-loving and cold-loving.
By heat-loving include fish living in the water, the temperature of which is not below 18 degrees. Cold fishes are individuals that easily adapt to low temperatures. They can safely live in the aquarium, the temperature in which, will not exceed 14 degrees. The maintenance of cold-loving fish is possible only in large and spacious aquariums.
It is noteworthy that if the heat-loving fish are planted in cold water, then they practically stop swimming. This suggests that significant damage has been done to their health. Preparing water for the aquarium, you should use the tips for beginners, which can be found in the special literature. So, it is possible to choose the optimum temperature for water only after it becomes known exactly which species of fish will live in it.
The thing is that in the literature for each type of fish is given the permissible threshold of the highest and lowest temperatures at which the fish will feel comfortable. In accordance with these parameters, you can choose the future inhabitants of the aquarium so that they all feel comfortable in the same temperature conditions. This will avoid a huge number of problems associated with the maintenance and care of the fish.
How much to defend the water for the aquarium?
Is there a need for water settling?
In order for the tap water to be normalized for replacement in an aquarium, it is necessary to remove from it all the harmful components – solid, gaseous and liquid.
Today, upholding is very rarely relevant. Solid components in the water supply system have isolated cases, chlorine water derivatives must be removed by air conditioning (chlorine gas is also removed), and liquid ones – only by special air conditioning. Polluted water settles for several hours, and with strong aeration much faster.
From all of the above, it is clear that it is best to use special additives for water. Settling water does not completely remove harmful substances, and in some cases it may even be harmful (a dusty film appears, stuffiness, etc.).
From personal experience:
- I collect the necessary amount of water for the substitution;
- add air conditioning according to the instructions;
- perform aeration for 15 minutes;
- I bring the temperature of fresh water (with air conditioning) into accord with the aquarium one;
- I fill, and that’s it.
The advantages of this method of water preparation: all harmful substances are removed, no need to wait until the water settles, the pots do not harm the interior of the room.
How to prepare the water?
Freshly tap water is not suitable for animal settlement. Reptiles, fish, amphibians and snails can adapt to it, but on condition that it infuses for several days.
Fresh, domestic water from the tap will destroy animals, because chlorine compounds are toxic to the sensitive organism of small creatures. On certain days, tap water contains different amounts of volatile substances, experts recommend turning on a shower and checking the steam and the presence of chlorine to check. If the smell is harsh, water should not be collected on this day.
Regardless of the season, weather and air temperature, domestic water will be different. Be observant if you want to settle the animals in clean water from impurities. Infused tap water is recommended for many pets and plants, it has an acceptable level of acidity: pH 7.0.
It is filled with small aquariums, but with an experienced razvodchiki warned that such water is poor in the mineral components necessary for animals. Rarely use a liquid from another aquarium, in which there is a stable biological equilibrium for normal life.
How to prepare water with permissible hardness?
Reduce stiffness by filtering and infusing. Sometimes, infused water (time – 2 days) from the tap add distilled, thawed or rain water. Plants such as roach and elodiea, reduce stiffness. There is another way – freezing. The collected water is frozen, and then thawed, defended and poured into the tank.
Increases the rigidity of the aquarium water by adding brine, pieces of chalk or limestone, coral chips to it. Coral crumb is recommended to boil (2 hours) to soften and prevent parasites. Only after all the procedures it is lowered into the tank.
It is better to run the fish in a day or two, until the water has acquired the necessary parameters. The temperature of the water in which the purchased fish, animals and plants lived should be identical to the aquarium. Again, use a thermometer, litmus paper to test. Do not neglect the recommendations that the life of pets was healthy and safe, because when kept in poor-quality aquatic environment, they may suffer.
What does water temperature affect?
Aquarium water that has a certain temperature can stimulate spawning. This applies to elevated water temperatures. However, this is not always useful for fish. So, the fish that spawn, you should not constantly keep in such conditions. Otherwise, to get offspring from them in the future will be simply impossible. Thus, when harvesting water for an aquarium, it is better to ensure that it is one degree below the norm.
Gaseous constituents of water
This type of substance evaporates through the surface of the water. Here one can consider the quantitative and qualitative compositions of dissolved gases in water. Gaseous substances in natural water enter into chemical reactions with other dissolved elements, due to diffusion they constantly circulate through the water mirror and are harmless and harmless to fish.
The method of water disinfection for your area can be found in the local water utility, this information will not be superfluous. At new water treatment plants, ozone and ultraviolet cleaning is applied, and such water can be added without fear (it is pointless to defend against oxygen and photons).
The outdated chlorine cleaning method is gradually becoming a thing of the past, but is still in use. Chlorine and its derivatives are poisons. They allow the destruction of both harmful bacteria and beneficial ones, as well as depending on the concentration of large animals and even humans.
Method of elimination of gaseous chlorine from water
Unpleasant smell of chlorine coming from freshly poured water, everyone knows. Water, being in a cup, ceases to smell after a while, and this means that chlorine molecules have evaporated.
Having made some observations on settling, it can be seen that chlorine evaporates quite quickly. It is not necessary to stand for water from the tap for more than a day, since the residual chlorine cannot affect the health of the fish.
The important point is the choice of dishes. The greater the area of contact of water with the environment, the faster the gas exchange occurs, and chlorine disappears. From this it follows that when settling water in a large-diameter basin, it will become suitable for an aquarium much faster than using a plastic bottle.
Ozone and its effect on fish
With ozone, things are somewhat different. It does not have a pronounced smell, although it carries freshness. Under natural conditions, we feel it during a thunderstorm, during the operation of air conditioners (ozonizing) and laser printers. Before water is supplied to the drinking pipeline, the process of its ozonization takes place, the ozone molecules are unstable and quickly pass into a stable compound – oxygen. Well, oxygen is not dangerous to fish.
What is pH and hardness?
pH is a pH indicator of the acidic environment. A pH of 7 is considered neutral because it is more favorable for most aquarium dwellers. In the case when it is less than 7, the water is alkaline. In order to easily determine the pH of water, it is necessary to purchase litmus papers with a color table, or specialized aquarium tests.
The second parameter of water is hardness. It is divided into temporary and permanent. Water hardness may also affect aquarium inhabitants.
In order to avoid unpleasant consequences, aquarium water should also be checked for permanent and temporary rigidity. It is measured in degrees and is calculated by adding the temporal and constant rigidity.
In the case when spawning of a certain type of fish is necessary, for example, such as neons, in which caviar can survive only in very soft water, water with low hardness content is used. However, for most avkarium fish species, water with a hardness content of less than 5 is not suitable for life and breeding. At the same time, too high water hardness, such as 25 degrees and above, is also destructive for most aquarium species. Of course, there are exceptions.
The norm, it is considered to be hardness from 5 to 25 degrees, which is favorable for the vast majority of different types of aquarium fish.
Aquarists who do not want to bother themselves with various dimensions can simply pick up certain types of fish that feel great in ordinary tap water.
