Tip 1: Why water is needed

Water - a chemical substance without color and odor with a fairly simple formula H2O. Meanwhile, it is difficult to overestimate its importance in the life of each individual in particular and the whole planet as a whole.

First of all, it is necessary to say about the role of water on our planet. Water on the Earth is present at once in three aggregateStates: liquid, solid and gaseous. Liquid water in the form of oceans, seas of rivers and lakes covers about 70% of the earth's surface, actively participating in the formation of the terrain, climate and weather on the whole planet. Water vapor is a part of the Earth's atmosphere, and ice cover, mostly represented in two regions: the Arctic and the Antarctic (although not only there). Water Is an indispensable substance on the planet, namelyin water, according to the generally accepted opinion, life originated. It is the biological role of water, because it is the substance that determines the possibility of the existence of all living things on Earth, playing the role of a universal solvent in which the basic biochemical processes of living organisms occur. Water Sufficiently dissolves both organic and inorganic substances, ensuring a high rate of chemical reactions in cells. Water remains liquid over a fairly wide rangetemperatures, and precisely in the one that is widely represented on the planet Earth at the present time. Covering a significant surface area of the planet, water is a natural habitat for hundreds of thousands of species. Without water, all living things on earth will immediately perish. The human body contains between 55% and 78% water, depending on weight and age, with a human body loss of more than 10% water can lead to death. A person needs to consume about 3 liters of water per day. As already mentioned above, water is a solvent for many substances, which is why it is used as an industrial solvent, as well as for cleaning objects of human activity. In addition, water as a heat carrier is used in heat networks and nuclear power engineering, and in some reactors it is also used as a moderator of neurons, which provides an effective course of the nuclear chain reaction.Water Actively used in fire fighting, ruraleconomy, also as a lubricant (for lubrication of bearings made of wood, plastics, etc.) and tools for splitting, loosening and cutting of rocks and materials.

Tip 2: Why does the water in the home aquarium flourish?

Aquarists often face the problem of water flowering. Such a plague affects home aquariums mainly in the summer, or if the container is in an excessively lit area.

Why the water in the home aquarium is flowering

The causes of flowering water in domestic aquariums

Aquarium water is oversaturated with variousMicroorganisms. They are on par with fish and other visible inhabitants of the aquarium participate in the life of the common house. Useful bacteria actively try and process the allocation of fish and surplus food, which is already starting to deteriorate. They also prevent the beginning of putrefactive processes in water and soil. If there are many useful microorganisms, the biological balance is established in the aquarium, and the water in this case remains very clean and transparent for a very long time. But the owner of the aquarium must take care of the water microcosm. If it does not clean the ground and does not change the water, the balance is broken. The amount of dirt in the ground gradually increases, the processes in the aquarium from the beneficial turn into putrefactive, and the water becomes acidic. That is, without the help of a person, the inhabitants of the aquarium can not cope with cleaning the habitat. As a result, all conditions for the growth and development of green filamentous algae have been created, which make water turbid. When the water blooms and becomes mucous-green, harmful microorganisms begin to multiply in it. Rotifers, ciliates and other similar creatures are colored green. From their incredible amount of water in the aquarium becomes more like a liquid jelly. The putrefactive processes that are inevitable during the flowering of water adversely affect the health of the aquarium's cultural inhabitants. Diseases and even death of fish are not excluded.

What to do to prevent water from blooming

Once in 10-15 days, you need to changeone-fifth of the water in the aquarium. Note that in small containers, water often blooms, so you need to clean them more often - every 8-10 days. Biological balance in aquariums with a volume of more than 100 liters is established for a long time. But you still have to keep a close eye on the state of the water, for it is more difficult to cure the water world than to maintain cleanliness. Whenever water is replaced, collect the waste of fish and excess fodder from the soil surface. This is done with a hose that sucks in all the dirt and the right amount of water. If the sun's rays fall on the aquarium, move it to another location. Blossoming water in this case needs to be changed completely. When changing water, carefully inspect the soil. If there are putrefactive processes there, it will smell strongly and become mucous. Such a soil should be discarded and put a new one.

Tip 3: Why you need to sterilize the banks

Save vegetables and berries for the whole winter can be, if they can be preserved. Jam, compotes, pickles and other preparations for a long time will remain tasty if the banks are carefully sterilized.

Sterilization of tare is necessary in order toKill macro- and micro-organisms. Even if the banks are thoroughly rinsed, some bacteria will not die. This can lead to product damage. Often mistresses notice how the brine becomes cloudy and starts to foam, which threatens with bombing. If you have not sterilized the jars, but there are no visible signs of souring, it is not a fact that canned fruits can not be poisoned. Microorganisms are not as scary as the products of their vital activity. With long storage, poisons can be formed that are deadly to humans. To avoid unnecessary problems, take some time to sterilize the container. To do this, thoroughly wash it with a detergent, rinse under running water and roll with boiling water. Pour a little water into the pan and heat. Top with a sieve or some kind of grate. Put the jars down with their necks and wait about 15 minutes. Carefully remove, taking a clean towel. Start to laying vegetables or pour ready-made jam. Sterilize the cans and in the microwave. In a clean glass container, pour 1 cm of water and put in the oven for 5 minutes. But this method has one and a significant disadvantage - high and large cans are not always placed in the electric appliance. Do not forget to sterilize the lids, because they can also have various microorganisms that can spoil your workpieces. Do not use old sealing gums - they are usable only once. Then air can enter through them. Iron lids with rust thrown without regrets. Even after sterilization, bacteria can be on them. When properly processed, the cans will be fragrant and useful for several years. The main thing is to observe simple rules of sterilization and never miss this stage of processing because of time saving.

Tip 4: Why you need to drink green tea

Green tea with regular use rendersA positive impact on human health. But few know exactly which and on which systems of organs. So why is it really worth drinking green tea?

Instructions
