Tap water without boiling is suitable as aquarium water, if it does not contain impurities of any metals, magnesium salts, calcium and other constituents that are harmful to fish and plants. All the air and chlorine contained in such water will evaporate in just a week of settling. Looking ahead, we note that you need to add or change the water also separated or boiled.
If you have access to a spring with spring water, you can use it. Just for safety, hold some cheap fish in this aquarium water and follow their well-being. if something goes wrong, it will not be particularly expensive.
If possible, before pouring water into the aquarium, take a portion of the soil and water used in another aquarium. Thus, you will bring the necessary microorganisms and accelerate the process of formation of the aquarium mode.
One of the most important parameters of aquarium water is its hardness. From the rigidity depends on the possibility of keeping and breeding certain types of fish and the cultivation of plants. Later, the water hardness in the aquarium is naturally stabilized: it will increase due to the evaporation of water, the vital activity of plants, fish and snails, since they absorb calcium from the water. By the way, it is believed that distilled water has zero hardness.
If the aquarium water is too hard, it can be softened. To do this, there are two simple ways: freezing and boiling. In the first case, the water is poured into a low-frost-resistant vessel of large diameter and put in the freezer. As soon as the water from the sides freezes, the ice is punched and the unfrozen water is poured into the sink. The ice remaining in the pot is melted. The water thus obtained has a much lower hardness. For the second option, water should be boiled for an hour, cool and drain 2/3 of the upper layer.
The value of pH (pH) is subject to certain fluctuations. For example, long-term solar illumination of an aquarium with a large number of plants increases its level to 9. At night, the amount of carbon dioxide in aquarium water increases (fish and plants breathe, absorbing oxygen), the pH drops to 6, which is not very good. Watch for aquarium water with liquid indicators. tests for aquarium water.
Now you can proceed to the actual filling of the aquarium with water. Fill the aquarium to a level of 10-15 cm, plant the plants and equip the aquarium. When the planting is completed, continue filling the tank to a level of 3-5 centimeters from the top edge of the aquarium.
After pouring water into the aquarium, complex processes will begin: rotting of broken plants may begin, the rapid development of microorganisms. Water from clear can become whitish-muddy. Do not confuse, after a while most of the microorganisms die, not getting enough nutrients, the water will again become transparent. To purify water from turbidity, you can settle in a daphnia aquarium, tadpoles, snails.
To protect the aquarium water from dust, the aquarium must be tightly closed.
The temperature regime of water in an aquarium should be constantly monitored, since many species of fish and plants have their own parameters, most favorable for their growth and development. The temperature in the aquarium depends on the location of the reservoir: for example, sunlight entering through the window of the room heats the water. Therefore, the more light, the higher the temperature of the water. The temperature difference of the aquarium water is undesirable, and its sharp fluctuations are generally unacceptable. Perhaps a smooth change in water temperature at 2-3 ° C, depending on the time of day.
