What water to pour into the aquarium
If you are a beginner aquarist, then you have to perform a lot of preparatory work for the launch of the aquarium. Even if you can not wait to start admiring the beautiful aquarium, remember that the rush here will only hurt. The volume of the aquarium is too small for it to be possible to create an independent ecosystem, so prepare for the fact that you will have to support it.
Features of tap water
In addition to regular feeding of fish, the aquarium requires lighting, heating, soil cleaning, Bay and water renewal. At the same time with the purchase of all necessary accessories and the study of the aquarium equipment, it is necessary to prepare the water. Once you have learned how to do this, you can apply this skill in any other setting of the aquarium.
All professionals agree that water should be poured into the aquarium tap. This is true if the only unnecessary element in the water is chlorine. Its rate for humans is 0.3 mg / l, and for fish the rate of 0.25 mg/l is already the limit. During the time from the Bay of water to planting the first plants in the aquarium, the water has time to settle, and the chlorine evaporates. During the second week, the introduction of microorganisms into the water in the form of bacterial ferments will help to create the necessary flora for the life of fish.
If you are not sure about the quality of water or want to be as accurate as possible in the calculations, you will have to find out the data on the composition of water in the reference Department of the water station. In addition to the presence of unnecessary impurities that do not fit the selected species of fish, the water can be disinfected:
Ozonation, which is already in most cases favorable.
Chlorine. Too chlorinated water should be additionally passed through a carbon filter or dechlorator.
With chloramine, which does not disappear on standing. In practice, its use is extremely rare, but it itself is able to form in water when chlorine is combined with ammonia.
The preparation and updating of water
Ignoring the renewal of water in the aquarium leads to its slow death with a decrease in the number of its inhabitants-old fish get used to the old water and become its hostages, and new fish can not take root in such an environment. Regular update of 20-25% of the water in the aquarium should be held necessarily once a week. During this time, the water has time to evaporate noticeably, and the remaining-clogged with waste. The exact amount of water replaced at a time, you need to adjust to the whimsicality of the fish you breed.
Fresh water is defended for at least 3 days, bringing it by special purification to the properties of water in the aquarium, so that the fish do not experience stress and do not get sick:
water from wells or boreholes is not suitable, as it may be too different hardness;
water from a lake or river should be heated to 70 degrees to remove harmful microorganisms;
rainwater is only applicable to rural areas and requires cleaning through a filter;
the water to be poured should be at room temperature of 22-25 degrees.
It is necessary to check water on three chemical indicators: pH, nitrites and ammonia. They are able to form the correct bacteriological parameters of water. In softer water, a friendly ecosystem develops faster. And fresh water, which has more oxygen, has a beneficial effect on the activity of fish and plant growth. Water is drawn from a cold tap and settled in a container, preferably with a maximum area of contact of water with air-for example, in a basin. To protect against dust, the dishes are covered with gauze and placed in a warm place. The quality of settling water is determined by the smell — it should be fresh and pleasant.
A large replacement of old water, when it remains less than 20%, is rarely carried out. This is a necessary measure that should be carried out with the appearance of fungus, flowering water, unwanted microorganisms and strong soil contamination. They indicate serious violations of the aquarium ecosystem, which can only be restored by replacing it.
