Wildlife reservoirs
The fauna of reservoirs in its habitat is divided into two main groups. The first is zooplankton, and the second is benthos. Zooplankton lives directly in the water column, and…

Water Treatment Equipment

It so happened that for most people, proper rest means a more or less close contact with water, because water for us has been a necessary condition for life itself and even for simply comfortable existence since ancient times. And therefore, an artificial pond in the country or in the garden near the house is becoming more and more common in the modern world. After all, how nice it is to come home from work or come a few days to the country to get the opportunity to complete relaxation.
Turning to the experts, you can order the construction of a pond of any shape, any design and size, but that’s not all. After all, an artificial reservoir is like a pet, which requires proper care.
An artificial pond is not an isolated system, it is in contact with the environment and therefore is significantly exposed to external influences that significantly affect its appearance and condition. This contact leads to the fact that the decorative pond loses the transparency of the water, and hence its beauty.
There are several causes of water deterioration. Often, water blooms occur due to active reproduction of algae, due to reproduction of unwanted bacteria and other protozoa in excess of the norm, which occurs in stagnant water and during hot periods of the year. Also, the deterioration of water quality is due to fallen leaves and fruits of trees, due to living creatures that inhabit an artificial reservoir, and products of its vital activity. Also, a decorative pond can be contaminated by animals living near it and drinking water from it.
You also need to remember about chemicals that fall into the water with rain and with the help of storm streams from the surrounding artificial reservoir area. As a result of all these processes, the water becomes turbid, dirty, begins to smell bad and look unpleasant.
In this case, it becomes necessary to clean the pond. To do this, you need to flush the water and clean the walls and bottom of the reservoir from sludge and dirt, while not forgetting the need to relocate the living creatures living there, another place for the cleaning period.
And for fish, and even for plants, cleaning the pond is stress, after which they will have to get used to new clean water and new microflora. Stress slows development, increases the risk of disease and can cause the death of fish and plants.
Filters are used to preserve the transparency of the water and its normal state. There are several types of filters: mechanical filters that filter and retain large particles and smaller debris; biological treatment, which decompose pond organics and neutralize the action of harmful substances; chemical cleaning, when harmful substances are decomposed into safe components by a chemical reaction method; ultraviolet cleaning when small algae, unwanted bacteria and other protozoa are sterilized with ultraviolet radiation.
The easiest way to rid your decorative pond of debris – fallen leaves, fruits, branches and other things – is by mechanical cleaning of the pond. Mechanical filters act in such a way that water, passing through a container with a porous material, is cleaned, as particles of debris stick to the filter material and remain in the filter.
Biological purification of the pond is based on the decomposition of substances to methane, carbon dioxide and hydrogen sulfide. This is done with aerobic and anaerobic bacteria. Usually, biological treatment of the pond is combined with mechanical. In the biological filter is placed a foam sponge or another porous material, on which bacteria settle, which feed on the organic matter that passes through the filter.
Pond chemical cleaning is done by adding chemicals to the water. This way you can neutralize algae, maintain the level of oxygen in the water and the level of acidity.
Also one of the possible methods of water purification is ultraviolet disinfection, which sterilizes microorganisms by acting on their DNA.
In order for the pond cleaning to be the most efficient and high-quality it is necessary to apply a filter system that combines several types of water purification. Modern equipment also often includes additional devices that allow you not to buy them separately later – for example, a device for aeration (water saturation with oxygen). To additional devices that will help cleaning the reservoir – this is a water vacuum cleaner and a skimmer. A skimmer is a device with which you can catch debris from the surface of a pond, and a water vacuum cleaner will help keep it clean.
So we told you how to keep your artificial pond or reservoir clean.
