At my summer cottage there is a pond in which water has bloomed. Water bloom is the active development of microscopic algae that cannot be seen with the naked eye. In a short period of time, they covered the entire surface of the reservoir, as a result of which even the fish were not visible. I want to share my story of how I managed to cope with this problem.
First of all, I cleaned the water with an iron rake. This is how I selected all the debris floating on the surface. Then I used live bacteria. For my pond, I needed 2 g of the preparation per 1m². The bacteria have contributed to a decrease in the content of ammonia and nitrogen in the water. With the introduction of bacteria, I also achieved a reduction in the nitrate content, which is dangerous for the life of fish. Then I resorted to aeration - this is the saturation of the water with oxygen artificially or naturally. This process is necessary for the vital activity of bacteria, since they settled on algae, stopped their respiratory system and as a result died.
In this process, a 60-liter aerator helped me. in sec.
The main representatives of my pond are water lilies. To prevent them from dying during cleaning, I had to remove them from the reservoir. I put on a waterproof suit and collected all the water lilies that I took care of for 2 weeks - so much time for me to clean.
Any artificial pond needs a beautiful, competent plant design. I want to share with you some useful tips.Plants with large leaves look fascinating in any lake. Among these, the main decoration will be a water lily. In addition to the main representative of the pond, the rates will be decorated with a plant with white flowers and a wonderful aroma called "aponogeton". In addition to the listed "inhabitants" will serve as an orontium and a yellow egg capsule.
Don't forget about oxygenator plants that prevent fluid contamination. Representatives of this species include marsh turcha and water buttercup. They live under water. Before planting, the plant must be placed in a plastic container containing clay soil. Then add a layer of gravel to the container and place it on the bottom of the pond. Plant oxygenator plants in June.
Plants that do not take root in the ground, but float freely on the surface, for example, duckweed, vodokras, zerushnik, will help prevent water bloom.
Choosing on these representatives, you need to know some of their features. The duckweed will very quickly cover the entire area of the reservoir, so it is preferable to decorate large bets with it. Vodokras, on the contrary, grows very slowly. It is best used in small backwaters.
The coastal zone requires special attention during the improvement of the reservoir. Its representatives are water-loving plants with beautiful flowers, for example, calendula, forget-me-nots and primrose. Calamus and sedge will be a bright spot of such a composition. We must also remember about the usual reeds, which will give naturalness to your lake.
Water can be needed in any situation. Thirst can catch a person by surprise anywhere, and then the need for purified water becomes the number one problem.
Water can be needed in any situation. Thirst can catch a person by surprise anywhere, and then the need for purified water becomes the number one problem.
If we talk about clean water, which is needed in case of emergency, for example, during a hike in the forest, then you can use an exotic method and purify the water with a snake.
You can take water from any body of water or swamp, but it will be full of pollution and pathogenic bacteria. Accordingly, drinking such water is strongly discouraged. But the plus of the forest area is that you can catch snakes there.
If you seriously expect to catch a snake, then first of all you need to know what it looks like so as not to run into a reptile dangerous to humans - a viper or other poisonous snake.
Given the fact that most people do not have great skill in catching snakes, you will have to try hard to get this snake in your hands.
And the most important thing is to never try to catch a snake if you do not understand snakes and cannot distinguish between them!
Snakes pass water through themselves, thus filtering it. Snakes are their own natural filter. The use does not require much effort and, accordingly, purify water with a snake won't be a big problem. To do this, you must perform a number of the following actions:
Although the water will become clean and not be harmful to health, it may not be so pleasant for someone to drink the water in which the snake was sitting. Besides, the snakes smell very unpleasant.
It is also important to note that you need to be careful when catching snakes.
These reptiles bite quite hard. Despite the fact that they are non-venomous, their bites are quite painful. It would be better to protect the body with clothes, and cover your face with a handkerchief or cloth, since snakes can throw themselves in the face.
Carrots are not a picky culture. But for a good harvest, you need to follow some recommendations when growing it, in particular, the rules of crop rotation.
In order to make kvass at home from dry kvass, you first need to prepare all the ingredients necessary for kvass, then make a leaven, and make kvass on its basis.

Ecology. This word now flashes in our everyday life much more often than arguments about the conquest of nature.
Polls have shown that those who are more or less versed in mushrooms are a minority. The overwhelming majority of people who go with baskets to the forests are poorly versed in mushrooms.
Algae and their spores, millions of microscopic microorganisms live in the water. In the spring, the water begins to warm up from the warm sun. It also triggers the processes of algae reproduction. And at the height of summer, when it’s time to swim and sunbathe, I don’t want to get into the reservoir because the water in it is not clean and not fresh, as we would like and, rather, resembles sorrel cabbage soup. Of course, algae themselves are harmless. Therefore, you can take water to water the garden. However, swimming in such a pool will not be very pleasant. In addition, sometimes so much algae accumulates that water foams on the surface. Each underwater plant participates in an active gas exchange process with the environment. As the algae grows and develops, they are surrounded by bubbles and rise higher to the surface.
There are several ways to deal with the bloom of a reservoir. One of them is the use of special drugs. The second is constant water replacement or good filtration. There is also another method - water shading. But it has one significant drawback. Yes, the pond will not bloom, but the water will not warm up either. And who will swim in cold water, even in the heat?
The use of chemicals in a water basin is also not always correct. It so happens that the reservoir is inhabited by fish, frogs. Living things are unlikely to tolerate such bullying well. At the same time, it will be unsafe for a person to swim in such water. Especially if you assume that little children will also perform water procedures in this reservoir. Inadvertently, you can sip a little water that has experienced chemical attacks, and the consequences will definitely not please.
The price of chemicals also plays a significant role. Therefore, everything is relative here. For example, if you need to prevent the bloom of a small, exclusively decorative reservoir, this is one thing, you can spend money, and it will not cost very much. Now imagine a pond of several hundred cubic meters of water - the kind in which fish can be found. It will turn out to be very expensive.
Continuous filtration of water will also cost a pretty penny. If the reservoir is small, then you can simply replace all the water or make sure that it is not completely standing, but running. When it comes to a large pool, it is important to ensure that the filtration takes place faster than the growth of algae. Otherwise, the system will simply be meaningless: the reservoir will still bloom. Therefore, the filtration must be high-power, and this will be very expensive. In addition to the question of price, it needs to be delivered somewhere, serviced, and carried out communications. As a result, the amount will be in the hundreds of thousands - which will turn out to be even higher than the cost of the reservoir itself. This is unjustified.
It often happens that when arranging garden ponds, the owner of a summer cottage or a country house rarely thinks about how to take care of it later. The main thing is the embodiment of the idea itself - a pool in the country or on the territory of a country house. And everything else is secondary. But this is not at all the case. You need to understand that a pond in a garden is not just a pool buried in the ground. And it doesn't even matter what material it is made of - plastic, concrete or PVC film. The most difficult thing is to ensure the functioning of the reservoir in its normal form.
Is the water in a decorative pond often polluted and blooming? Our tips will help you solve this problem quickly and easily.
Blooming water - the result of active reproduction cyanobacteria (as in science it is customary to call blue-green algae), which not only spoil the appearance of the pond, but also disrupt its ecosystem. The water becomes greenish and acquires an unpleasant odor, waterlogging of the reservoir begins. It is dangerous because the overgrown algae do not allow light and air to penetrate deep into the interior, hindering the growth and development of other aquatic plants. Lack of sun and oxygen leads to the death of fish living in the pond.
Excessive cyanobacteria is the main cause of water bloom
Spring water bloom is a natural process that serves to restore the ecosystem of the reservoir after the winter period. The alarm should be sounded only if the spring flowering continues. more than 10-14 days... In the summer period, start the fight against waterlogging as soon as the first signs of it appear. There are several reasons for this process:
Spring water bloom should not last more than 10-14 days
Timely cleaning of the reservoir is a guarantee that over time it will not lose its appearance and turn into swamp... Full purification of the reservoir consists in draining all the water, relocating the inhabitants of the pond to reservoirs and mechanical cleaning of the bottom and walls of the reservoir from silt and algae. So that you do not have to carry out this procedure too often, use our tips:
Remove duckweed regularly from the pond surface
There are several ways to clean your pond:
Remove leaves, twigs and other organic debris from the pond surface
If, despite all the measures you have taken, the water in the pond does not become clear, you will have to resort to the very least - complete draining of water.
Draining the water completely is a radical measure for cleaning a pond
Timely pruning of trees and shrubs growing at the water's edge will help to avoid additional water pollution in the pond.
Installation filter Is one of the most popular ways to maintain a balanced ecosystem of a water body. This device not only purifies water from harmful impurities, but also helps to saturate it with oxygen.
The filter not only cleans the water from harmful impurities, but also helps to saturate it with oxygen.
In standard filters for artificial reservoirs, a three-stage cleaning system is used: mechanical, biological and ultraviolet. Such a device not only cleans the water from mechanical debris that causes waterlogging of the pond, but also leaves harmful plants without nutrients. All filters are divided into 2 large groups:
Please note that using a filter will not save you the hassle of manually cleaning your pond.
Skimmer Is a device designed to clean the surface of a reservoir from debris. At its core, a skimmer is a pumping device that filters out water and sends the remaining dirt into a special basket. Depending on the place of installation, these devices are divided into:
The floating skimmer is very effective in cleaning the surface of the water from duckweed and silt
The main disadvantage of the skimmer is that it cannot clean the pond from the accumulated silt. That is why skimmers are most often used as an additional, rather than the main, means of cleaning a reservoir.
Principle of operation water vacuum cleaner practically does not differ from a conventional vacuum cleaner. This device draws in water from the bottom of the pond and filters it, sending the accumulated dirt and sludge in the pond bowl into a specially designed dirt collector.
The water vacuum cleaner is convenient and easy to use
Vacuum cleaners are divided into manual and automatic... They differ from each other in that the automatic device moves along the bottom of the reservoir independently, without human assistance.
Water vacuum cleaner it is convenient to clean the bottom of a film or concrete pond. It is categorically contraindicated to use it for the care of a reservoir, the bottom and walls of which are covered with pebbles with a diameter of less than 10 mm.
This cleaning method requires great care, as careless handling of chemicals can lead to the death of cultivated aquatic plants and fish living in the pond. Therefore, experts recommend using this method in exceptional cases. Purchase chemical to clean the pond, you can in a specialized store.
The safest will be to use chemicals in the spring, before pouring fresh water into the pond and launching fish into it (2-2.5 weeks before the expected date of the bay). Instead of special products, you can use solutions potassium permanganate or brilliant green (0.1-0.2 g per 1 cubic meter).
Disembarkation cultivated aquatic plants - a very effective way to combat waterlogging of a reservoir:
Water lilies not only decorate the pond, but also interfere with the growth of green algae
The faster cultivated plants grow, the less nutrients they leave for blue-green algae in the water and weeds on land.
Large-leaved aquatic plants such as lilies and water lilies also protect the water in the pond from overheating.
It is not so difficult to avoid waterlogging and blooming of a reservoir. Remember, preventing contamination is much easier than fighting it.
In natural reservoirs, the water level often varies greatly throughout the year. That is why you must first study what level of water fall in your reservoir, otherwise you can not guess and then in a summer drought all plants may die or coastal plants will flood in the spring.
In addition, in an artificial lake, most often as such, there is no zone No. 5 (a group of moisture-loving, growing well in a humid environment), since water does not leave the created bowl. This means that you can plant any kind of plants around the lake. Also, a lot will depend on what kind of fish and in what quantity is found in your natural reservoir.

Preliminary work: Analysis and synthesis of literature, development of long-term planning, a selection of experiments with a description of the conduct. Learning with children proverbs, sayings and poems about water reading stories, fairy tales of a cognitive nature, viewing illustrations on the topic of a conversation on the topic: "Where can you find water?", "Who lives in water?", "Who needs water" observations in nature in different ways seasons of the year didactic and developmental games, games with water, observation of puddles during a walk (reflection of objects, experiments with water (flows, spills, has no shape).
Children, many guests have come to us today, let's say hello to the guests. (Say hello)
Today I brought a jar with an extraordinary substance. What is in it, what substance, you will find out by guessing the riddle:
Who then is our first friend
Remove dirt from your face and hands?
To rain from the sky
Slides showing the sea, river, lake and stream appear on the screen. A record of the murmur of a brook sounds.
- What do you see on the screen? (answers).
- How can all this be called in one word? (Water)
- That's right, water. All rivers, seas, lakes are composed of water.
- And here is our planet. This image was taken from space. Earth is a blue planet.
- Why is it called that? (Because there is a lot of water on it.)
Guys, who do you think needs water? (Answers of children.) That's right, people, plants, animals and birds need water.
Speech game "Finish the sentence": "People (animals, birds, plants) need water in order to ..." (Children's answers)
-Water is made up of many small drops. Look at the screen, it is a drop of water.
Fluffy cotton is floating somewhere
The lower the cotton wool, the closer the rain. (cloud, clouds)
Let me be small, well, so what!
I'll spill all over the yard! (puddle)
I run like a ladder ringing pebbles,
You will recognize me from afar by the song! (Creek)
To the right is water and to the left is water,
Ships sail here and here and there
But if you want to get drunk my friend
Every sip will be salty. (sea)
It is necessary to conserve water, because the supply of fresh water on our planet is decreasing, due to the poor environmental situation, rivers become polluted, dry up, some small rivers disappear, and deep-water rivers become shallow.
Remember the proverb: close the tap tighter so that the ocean does not flow out.
Educator: Let's repeat it together.
Look at the picture: when the sun heats up, the surface of the reservoir turns into steam and rises into the air. High above, the moisture-laden air cools, and clouds and clouds are formed, which, with the help of the wind, move in the air and fall to the ground in the form of precipitation: in the summer in the form of rain, in the winter in the form of snow. Water droplets in nature walk and move in a circle.
I will be mother Cloud, and you will be droplets. Do whatever I tell you.
It's time for the droplets to hit the road.
Drops flew to the ground, let's jump. It became boring for them to jump one by one. They got together and flowed in merry rivulets (the droplets make up rivulets holding hands). Streams met and became a large river (streams are connected in one chain). Droplets float in a large river, travel. Flowed, a river flowed and fell into the big ocean (children are rebuilt in a round dance and move in a circle). They swam, the droplets swam in the ocean, and then they remembered that mother Tuchka told them to return home. And then the sun just warmed up. The droplets became light, stretched upward (crouching droplets rise, then stretch their arms up). They evaporated under the rays of the sun and returned to mother Tuchka. Well done, droplets, they behaved well, they did not climb the collars of passers-by, did not splash.
So, we learned that water can be different: sea, river, etc.
And we will now check some of its properties with you. (The teacher invites the children to go to the tables for the experiment).
Experience 1 "Water is a liquid".
Water is liquid. It flows. It can be poured into anything: into a glass, into a bucket, into a vase. It can be poured, poured from one vessel to another.
I suggest trying to pour water from one glass to another.
Experience 2 "Water has no smell".
Now, I suggest you smell the water. Does the water smell like anything?
Conclusion: water does not smell, it has no smell.
Guys, what color do you think the water is? (Child's answer). We will check it now
What color is the milk? (white). Can we say about water that it is white? (Answers of the child). Dip a small toy into a glass of milk, whether it is visible or not. Then into a glass of water.
Conclusion: water has no color, it is colorless
And I know that water can change its color. Do you want to be convinced of this?
Now I will add a magic crystal (potassium permanganate) to the water and we will see what happens to the water. Has the water changed its color? And now I will add a magic drop (brilliant green) to the water. Let's see what happens to the water. Has the water changed its color? (Answer).
Conclusion: water can change color depending on what is added to it.
And now, I suggest you taste the water (the child is offered boiled water). What is she like? Sweet? Salty? Bitter?
Conclusion: water has no taste, it is tasteless.
Let's do a little experiment with you. Put in a glass of water the substance that is on your table (an adult demonstrates). Stir, now taste the water. How did it taste? (Answer). What do you think you added to the water? (Answer).
Conclusion: it turns out that water can take on the taste of the substance that was added to it.
And now we will conduct an experiment. Here are 2 glasses of water. Are they the same water?
Children: No clean and dirty.
Educator: Would you like to drink this water? Why? And this one? Why? Let's try to clean dirty water together. To do this, take a funnel, put cheesecloth in it and start passing dirty water through this funnel. Let's see what we get?
Educator: What did the guys do?
Educator: What happened to our gauze?
Educator: Yes, we cannot live without clean water. We only need clean water.
"Can paper be glued with water?"
We take two sheets of paper, move them one to one another in the other direction. We moisten the sheets with water, lightly press, squeeze out excess water, try to move the sheets - they do not move.
Conclusion: Water has an adhesive effect
Air is lighter than water - bubbles
Water is able to hold objects on the surface.
You recently asked me a question: how do plants drink water?
Experience 10 "How plants drink water."
Children, how do you think plants drink water? (Using the roots).
We place the “trunk” of a tree cut out of blotting paper into a vessel with water and observe how the water rises to the “twigs”.
Conclusion: in nature, plants receive water from the soil, so they need to be watered.
Educator: Guys, what did we do with you today? What new things have you learned about water? Did you enjoy working in the laboratory? What seemed the most interesting? (Answers of children.)
The teacher thanks the children for their participation in the experimental activities and presents them with the "Young Researcher" badges.

If you do not fight the duckweed, then it can fill the entire reservoir, turning the pond into a swamp
Sometimes the owner of the pond notices that the duckweed and reeds are taking over more and more space and turning the artificial reservoir into a sloppy puddle or even a swamp. Duckweed is difficult to remove - it tends to fill all the free space. However, with regular and careful maintenance of the reservoir, its growth can be limited.
Floating plants can also help.They also want to receive oxygen and nutrients, so they will take part of the area from the duckweed. You should not populate the pond with plants and animals taken in natural conditions. New residents may well bring duckweed with them.
The shallow part of the reservoir (0.5-0.7 m deep) should not be too large - experts advise that it occupy about a third of the surface area. The fact is that with the onset of spring, shallow water quickly warms up and bottom sediments - dead plants, waste products of fish and animals - release phosphorus and nitrogen compounds, the so-called biogenic substances, which enter the water column and cause an outbreak of microalgae bloom. This bloom is sometimes very violent, as a result of which the supply of nutrients is depleted and microalgae begin to die off quickly. Dead organic matter rots, absorbing dissolved oxygen from the water. And due to the lack of oxygen, fish are killed and the pond rotted. This process of bursting flowering and subsequent death can be repeated several times during the summer. And the shallower the pond, the more often such phenomena will be. To soften and stretch the bottom heating in time, it is necessary to make most of the reservoir deep enough - for the climatic conditions of central Russia it is more than 2.5 m.In order to clear the pond of greenery and reduce the development of unicellular algae, the reservoir should be protected from too large the amount of sun (shade with plants with leaves floating on the surface or build a pergola or gazebo on the south side). It is not recommended to shade the pond with duckweed - it grows rapidly and begins to prevent oxygen from entering the water. Then you will have to think about how to clear the duckweed from the pond, and not use it for good. The shallow part of the pond is usually occupied by submerged aquatic vegetation, which also feeds on nutrients and resists the active growth of algae. In addition, filter-feeding organisms live in shallow water.
