Water for an aquarium has to be the clean, transparent, containing all minerals, necessary for life of fishes and plants. To prepare aquarian water, time and special means will be required. So, take usual tap water …
Tap water without boiling will approach as aquarian water if does not contain impurity of any metals, salts of magnesium, calcium and other components harmful to small fishes and plants. All air and chlorine which contain in such water all for a week of upholding will disappear. Running forward, we will notice that it is necessary to add or change water also otstoyanny or boiled.
If you have an access to the spring with spring water, it is possible to use it. Only for secure take in this aquarian water of some cheap small fishes and see to their health - if something goes not so, then it will not be especially unprofitable.
If there is an opportunity, before filling of water take a part of soil and water in an aquarium, used in other aquarium. Thereby you will bring the necessary microorganisms and will accelerate process of formation of the mode of an aquarium. One of the most important parameters of aquarian water is its rigidity. The possibility of maintenance and cultivation of certain species of small fishes and cultivation of plants depends on rigidity. Later hardness of water in an aquarium stabilize naturally: will raise due to evaporation of water, activity of plants, small fishes and snails as they acquire calcium from water. By the way, it is considered that the distilled water has zero rigidity. If aquarian water too rigid, it can be softened. For this purpose there are two unpretentious ways: freezing and boiling. In the first case water is poured in a low frost-resistant vessel of large diameter and put in the deep freeze. As soon as water from sides freezes, ice is punched and not frozen water is poured out in a sink. The ice which remained in ware is melted. The water received thus has much more smaller rigidity. For the second option water should be boiled within an hour, to cool and merge 2/3 top layers. The value of a pH value (rn) is subject to certain fluctuations. For example, long solar illumination of an aquarium with a large number of plants increases its level to 9. At night in aquarian water the amount of carbon dioxide (fishes and plants breathe, absorbing oxygen) rn increases falls up to 6, it is not really good. You watch an indicator of aquarian water by means of liquid indicators – tests for aquarian water. However, for acceleration of process of preparation of aquarian water it is enough to buy in pet-shop the aquarian water conditioner - special means which neutralizes harmful impurity and does water suitable for settling in 10 minutes. It is necessary to observe a conditioner dosage strictly. Now it is possible to start actually filling of an aquarium water. Fill an aquarium to the level of 10-15 cm, plant plants and equip additionally an aquarium. When landing of plants is finished, continue filling of capacity to the level of 3-5 centimeters from the top edge of an aquarium. After filling of water in an aquarium difficult processes will begin: rotting of the broken-off plants, rapid development of microorganisms can begin. Water from transparent can become whitish and muddy. Be not confused, after a while the majority of microorganisms perishes, without receiving enough nutrients, water will gain transparency again. For water purification from turbidity it is possible to occupy in an aquarium of a water flea, tadpoles, snails. For protection of aquarian water against dust, the aquarium needs to be closed densely. Temperature condition of water in an aquarium needs to be controlled constantly as many species of fish and plants there are the parameters, most favorable for their growth and development. Temperature in an aquarium depends on the location of a reservoir: so, for example, the sunlight getting through a room window heats water. Therefore, the more light, the water temperature is higher. Temperature drop of aquarian water is undesirable, and its sharp fluctuations in general are inadmissible. Perhaps smooth temperature change of water on 2-3os depending on time of day.
