There is no absolutely pure water in the world, it is mined in laboratories using step-by-step distillation. Water from a water supply system or natural source always contains impurities of various substances that play an important role in the ecosystem. Considering that many modern people keep fish at home, everyone wants to use the highest quality water for them. But what should be the water so that it can fill the home aquarium?

What you need to know about spring water
For a long time it was believed that spring water, recruited from a crystal clear stream, is best suited for ornamental freshwater fish. Perfectly clean, transparent, odorless and dirt free. that’s exactly the kind of tank you can fill! It turned out that typing this is not always safe. Its difference from tap water is high rigidity. Even the soap in it is difficult to dissolve, what can we say about fish food. Due to the high content of magnesium and calcium salts, it has a detrimental effect on the health of the fish and their offspring (eggs). Unfortunately, the water from the spring is not recommended to add to an artificial aquarium. Occasionally it is mixed with water to increase rigidity.
Distilled and rainwater
Since the springs have increased hardness, can it be better to pour soft water into the tank. rainwater or distilled water? Again, not always. just mixing it with the plumbing. There are fish that love the environment with softened water, but many freshwater species still prefer medium, neutral water. Such water flows in domestic rivers and lakes. you can pour it purified into the aquarium, filling it with not all the space.

What habitat most love aquarium fish
What water is needed for an aquarium? Combining water from different sources, it is impossible to achieve the ideal parameters. How many fish, so many requests. Some fish can live in the melt water of mountain lakes, others. in the brown marsh. In the first case, the water is very hard, in the second. soft. Fish have to settle in a different environment. It turns out that some fish are orderlies who love rotten water, others do not tolerate such parameters. Rotten environment is detrimental due to humic acids. Many freshwater biotopes of our country have pH neutral water, medium acidity, low alkalinity. For most aquarium fish, it is suitable.
Aquarium water for unpretentious fish
Water that must be prepared for not very capricious ornamental fish requires preliminary preparation. In the general aquarium it is necessary to fill in soft (sometimes medium hard) pH-neutral water. This can be plain tap water. In it, live-off and viviparous fish, which perfectly adapt to different conditions, take root well.

The degree of hardness can be measured using litmus paper, the temperature of the water. with a thermometer. Water of high degree of hardness is recommended to be mixed with soft rainwater (filtered) or distilled. Also, water from clean, melting snow or ice. The listed types of water can be collected in a clean container only after prolonged precipitation; it is enough to pour 30% soft water into infused water from the tap.
Water from the tap can not be poured immediately. It is better to pour it into a glass, and see if the glass is covered with bubbles, whether a strong smell will emanate. Such water is saturated with compounds of gases that fell into it during filtration at the treatment plant. Having let the fish in such a liquid, the pet’s body will instantly become covered with bubbles, which will penetrate into the gills and internal organs. As a result, the fish will die. In addition to gas, chlorine is added to water for disinfection, it will also poison living beings.
To get rid of gases, tap water can be poured into glass containers, and let it settle there for several days (2-3 days). There is another quick way: pour water into enameled ware, bring it to the stove to 60 or 80 degrees, set aside and cool. Boiled water is harmful. it leaves on the walls of dishes scale calcium carbonate and magnesium. Boiled water can be poured into spawning, but in extreme cases. To fill the entire area of the aquarium with boiled water will take a long time. Another nuance. boiled water kills all the useful microflora.
If you do not have water supply (this occurs in our time), you should go to a clean river or lake (where there are no signs “No swimming!”, Etc.), and take water from there. If it is clean, river fishes (perch, bream, roach) really live and flourish in it, there is a water grid plant, which is a good sign. To destroy parasites, such water is heated in an enamel pot to 80-90 degrees, but not to make boiled water out of it. The parameters it will be different from the liquid from the tap, so think about whether to take such a risk. You can go to another house, and get running water there.
In addition to thawed, spring, rain and distilled water, it is advisable to pour 30% of the water from the old aquarium to the infused liquid from the tap. If he was kept safely, the fish and plants did not hurt there, the water in him was not muddy. this is a find. In the old (residential) aquarium water, whether it has been poured from a tap for a long time, there are many useful microbacteria that will create in the new dwelling the natural biological environment. In a residential aquarium environment contains a number of organic impurities that are very useful for the aquatic environment. They make the water more acidic, do not allow the putrefactive and pathogenic bacteria to multiply. If high-quality and proven water is poured into the tank, all its inhabitants can be healthy.
