Blooming is the main problem of any artificial reservoir. This inevitable process is caused by the rapid development of phytoplankton, and it occurs especially rapidly in the middle of summer, when the water temperature in the pond reaches 20 degrees or more.
In a static and closed reservoir, algae grow even faster, preventing the full functioning of plants and other inhabitants of the reservoir.
As a result, in just a few weeks a pond with clean water can turn into a real fetid swamp. In order to maintain the purity and transparency of the water in an artificial pond, as well as create favorable conditions for the life of its inhabitants, it is necessary to organize a filtration system for the reservoir.
The modern market offers a huge selection of pond filters, which differ not only in their operating principle, but also in their performance.
The most widespread are pressure and flow type filters, as well as UV filtration systems. Let's look at the advantages and features of different filters for artificial reservoirs in our review.
Submersible, pressure or flow-through pond filter - which is better?
When choosing the most suitable filtration system option, there are several factors to consider:
- dimensions, depth and volume of the reservoir;
- presence/absence of fish and other living creatures in the pond;
- local climatic features;
- power of existing pumping equipment.
Pressure filter - a practical solution for a country pond. It is an effective water treatment system, which includes a deep-well pump and a container with filter media.
The pump takes water from the bottom of the pond, after which it goes through several stages of mechanical and biological treatment and returns to the reservoir.
The filter itself can be easily hidden in the ground next to a reservoir, for example, disguised as an alpine hill or stream. The tightness of the device allows it to be partially immersed in a body of water.
After passing through filter sponges and other media, the purified water naturally flows back into the reservoir. The advantage of flow-type filters is ease of maintenance and relatively low price.
For small-volume reservoirs, a submersible (floating or underwater) filter will be quite sufficient.
These are small mobile water treatment systems that do not require stationary installation of pressure hoses and installation of additional pumping equipment - the filter itself and the pump are located in one compact housing.
Simply place the device in water and connect to the power supply to obtain a clean and balanced aquatic environment.
- UV filter is a useful addition to mechanical cleaning
Modern filter models, in addition to a multi-stage mechanical cleaning system, are often equipped with ultraviolet sterilizers - a special UV lamp.
Such sterilizers are the most effective equipment today for combating bacteria, viruses and fungi living in the water column.
Protection from such negative factors is extremely important when keeping and growing fish and underwater plants that are demanding on living conditions in a pond.
UV sterilizers irradiate water with ultraviolet light, killing harmful microorganisms and preventing the formation of all types of blue-green algae.
By equipping an artificial pond with an ultraviolet sterilizer, you can forget about the need to purify the water with chemical reagents.
Bottom line - which option to choose for a decorative pond with fish
Fish (especially ornamental breeds) are very demanding on the oxygen content in water, and they actively excrete waste products.
Therefore, it is extremely important to install a productive filtration system in your garden pond to maintain a healthy biological balance.
When choosing a filter, you should be guided by the characteristics of the reservoir, as well as the number of aquatic inhabitants.
- So, when choosing a filter for a large fish pond with a volume of 100-150 cubic meters, we recommend paying attention to pressure pond filter Clear Control 100SE produced by VELDA (Holland). This filtration system is installed on the shore of a reservoir and includes three levels of purification: ultraviolet sterilizers (2 lamps of 55 W), mechanical and biological purification filters.
- A good alternative for a large pond would be flow filter Biotec ScreenMatic 140000 from OASE (Germany). It can easily clean a pond with a volume of up to 60 cubic meters.
- For a pond of medium volume (12-15 cubic meters), a compact pressure filter Clear Control 50/2 from VELDA (Holland) or a flow filter BioSmart set 24000 from OASE (Germany) will be sufficient.
- For a miniature decorative pond with fish, a submersible filter will be quite sufficient "OASE" Filtral UVC 2500 or Filtral UVC 5000. All Oase pond filters offer reliability and performance. Thus, the models listed above, with their compact sizes, will effectively clean a pond with a volume of up to 2.5-3 cubic meters.
The dacha pond resembles a small world in which its own special life is seething: plants develop and bloom, underwater inhabitants scurry about, something new happens every day. To ensure the vital activity of a reservoir, it must be cleaned at least occasionally using one of the generally accepted methods - using a skimmer, vacuum cleaner, pumping station or homemade device. To gently clean water from silt, it is enough to assemble a pond filter with your own hands and connect it to the power supply.
There are several conflicting opinions about whether an additional treatment device should be installed in a pond. Supporters of natural cleaning believe that there is no point in filtering a natural reservoir, since everything inside it is already provided for by nature itself.
A picturesque, beautiful pond with clear, crystal clear water - the result of considerable work to clean it of debris, silt and algae
Balance is established thanks to useful “swamp” plants, which perform a number of useful functions:
- deliver oxygen to water;
- block the development of harmful algae;
- enrich the environment with necessary chemical elements;
- increase water transparency;
- are wonderful decor.
For small ponds, elodea and hornwort are suitable. Representatives of underwater fauna are also peculiar cleaners. For example, crayfish and grass carp feed on duckweed and other polluting algae.
The dark green hornwort, a popular aquarium plant, has proven itself to be an excellent pond keeper. Grows well in any climate and grows quite quickly
In reservoirs created artificially on film material, biological treatment agents containing cleaning bacteria are often used. They kill algae but are not suitable for fish ponds. One of the gentle solutions is the use of peat mixtures, which make the water less hard and prevent the development of algae.
Many are sure that it cannot be done without human intervention. Be sure to remove dry twigs and grass, fallen leaves and other debris from the surface of the water. If the water is too cloudy and contaminated, it is necessary to use special ones, which will be very expensive, or homemade devices, which are much cheaper and more accessible. Let's look at two options for homemade filters for a garden pond, which can be made quickly and inexpensively.
Option #1 – filter from a grocery basket
What kind of things do dexterous summer residents not adapt for their inventions! Any container with holes in which you can put filter components will be suitable as a filter container. The homemade filter has proven itself remarkably well when cleaning a pond with a mirror size of 2.5 m x 3.5 m.
The top of the case is hermetically sealed with a piece of durable plastic or thick film folded in several layers and secured with self-tapping screws, wire or clamps
List of required materials:
- a medium-sized plastic grocery basket as a body;
- drain siphon;
- submersible pump Atman AT-203;
- silicone sealant;
- gasket tape;
- fitting + nut (brass set);
- 2 clamps;
- pieces of foam rubber;
- 4 hard washcloths;
- PVC hose (1 m).
Many of the listed materials can be easily found in the country, others are sold in the construction supermarket. There is a chance to buy the Atman AT-200 series pump in the “Everything for Aquariums” store. The pump perfectly cleans the water and at the same time enriches it with oxygen. Several devices are included to adjust the power. The submersible motor operates safely and has low noise levels. The device operates on a 220V network and has a power of 38W. For a small unit it has an acceptable performance of 2000 l/h. Perfect for ponds up to 2 meters deep.
A pond half cleared of algae. The water is still cloudy and has a greenish tint, but no harmful plants are observed, and the bottom is cleared of silt
Any material that absorbs or retains dirt can be used as filter components: expanded clay packed in agrofibre; foam mats, rolled into rolls; plastic mats with holes; old washcloths.
For ease of use and further cleaning, filter materials should be large in size, ideally the size of a basket
All this is loaded in layers into a container (basket), then the siphon and hose are attached using sealant.
The hole for the siphon is drilled on the side so that water flows freely into the filter. The connection between the siphon and the body must be thoroughly coated with sealant.
The pump is immersed in water and connected to the network. For safety reasons, the socket must be packed in a waterproof casing.
Any network connections must be tightly closed from the outside environment. The casing can be made of durable plastic, a thick piece of rubber or leather
It is not necessary to overflow - if the filter becomes dirty, the water will naturally overflow and go into the drain.
Material on how to clean a pond or small reservoir yourself will also be useful:
Option #2 – plastic bucket filter
The second homemade pond filter is a submersible device that must be installed at the bottom of the reservoir. The volume of the pond is about 5 m³, the depth is from 1 m. The design can be any, but the chosen option is the cheapest and most functional, reminiscent of factory filters sold in stores.
General view of a homemade filter device: a capacious housing with filter material (foam rubber) and a lid with a rigidly fixed aquarium pump
Anyone involved in, or at least interested in, aquarium hobby knows several popular pump models. One of the most successful is the Polish device AQUAEL FAN 2. The advantages of the device lie in its technical characteristics: reliability, creation of the desired flow, excellent air supply and atomization.
The pump has two main parts: a housing for the filter; housing with motor (plus speed controller and pipes). Power is supplied from a standard 220 V network, power – 7.2 W
What is the frame made of?
You will need a plastic bucket with a capacity of 10 liters, which acts as a housing for the filter element. It is desirable that the plastic be relatively durable and withstand a load of at least 15 kg. For decorative purposes, the color of the “underwater” bucket should match the color of the bottom, that is, be brown, gray or black.
A little modification is required for full functionality. It is necessary to drill holes of small diameter (4-5 mm) in the side walls of the bucket - water will flow into them for cleaning. Some types of plastic are fragile, so you need to drill very carefully. You need to cut a large hole in the lid to secure the filter in it. You also need a little ventilation for air to escape - another hole in the lid, but this time small - 3 mm.
When calculating the diameter of the passage holes, you should take into account the size of particles of silt or debris that may block the flow of water for filtration
Filter assembly procedure
Foam rubber is ideal as a filter material - it perfectly absorbs moisture, traps dirt and is easy to clean. The optimal layer thickness is 50 mm, but other formats can be used. Foam mats are used several times.
Assembly instructions:
- We fix the filter housing to the pump cover using sealant or hot melt adhesive.
- Attach the pump housing to the cover.
- We lay foam mats along the walls of the bucket. We put two or three stones with a total weight of 5 kg on the bottom - as a weighting agent.
- Fill the rest of the bucket space with foam rubber.
- Secure the lid using wire or clamps.
A thick layer of waterproof sealant or hot melt adhesive will protect the connection between the cover and the pump body from water penetration into the top of the device
Connection and installation of the unit
To operate, the device must be connected to a 220 V power supply. The connection between the plug and socket must be protected from any moisture. To do this, you can use a casing made of moisture-repellent material. An RCD installed on the line will trip if there is a current leak and turn off the network.
The diagram shows the water cycle during the purification process: under the influence of the pump it enters the filter, and then, already purified, back into the pond
To install the filter, you need to select a flat section of the bottom, preferably in a deep place. We lower the filter into the water, after which it will naturally sink to the bottom of the reservoir.
Then we connect the power supply and arrange a place for water outlet after cleaning. For aeration, a thin hose should be attached to the pump, the other end of which will be above the water surface.
There are many modifications of self-made filters for cleaning a pond, and to increase productivity, each craftsman can bring something of his own, functional and useful.
In order for living organisms of different species, fish and plants to exist in an artificial reservoir, you will need to take care of the purity of the water in it. The rate of water pollution in a pond is influenced by many factors: leaves, dust, debris, rainwater, and exposure to sunlight. According to experts, the main factors in this negative process are excess nutrients and the accumulation of silt in the bottom layers. The reason for the appearance of a large amount of organic matter is the vital activity of fish and the natural decomposition of the remains of dying plants. The sludge that settles at the bottom gradually becomes a medium for the development of harmful bacteria and fungi. Naturally, against this background, there is a significant decrease in the level of oxygen in the water.
Proper design of a decorative pond - we provide a filtration system when designing
Changes in the reservoir will ultimately lead to the active colonization of it by algae, which are microscopic blue-green thread-like formations; when they decompose under the influence of bacteria, a large amount of oxygen is consumed. At the same time, fish and plants begin to feel the lack of the latter, and there is a threat of infection by infectious diseases.
This suggests the need to use water filtration systems or biological agents. The choice in favor of one or another option can be made only by studying in detail the relationship between the dimensions of the reservoir and its population of vegetation and fish. The design of a filtration system should be done during the construction of a reservoir: the small size of the pond can become an insurmountable obstacle to their installation.
A properly selected and installed filtration system for a decorative pond will turn the pond into a biologically balanced system that can decorate the landscape of the site in any style.
Pond filtration using minerals
A very effective option is water purification using zeolite, which is placed directly into the pond, placing it in special nets or placing it in filters. As liquid passes through, minerals retain all organic particles and microalgae.
Zeolite is valued for its ability to extract and absorb harmful breakdown products of biological substances from water. To purify each ton of water throughout the season, 1 to 3 kg of zeolite will be required.
How to clean the surface of the water
The question of cleaning the surface of the water is indeed very important - fallen leaves, settling to the bottom, will lead to the formation of silt and cause putrefactive processes in its thickness. The natural ecosystem of the pond will be disrupted; shading of the lower layers of water will lead to a significant difference in temperature between the transparent upper layer and the darkened lower layer. The easiest and cheapest way to clean the surface of the water is a special net, models with a metal edging that prevents damage to the mesh seem to be very convenient.
In autumn, when leaf fall is very active, it is recommended to stretch mesh.
A more expensive, but effective and easy-to-use device is a surface filter called skimmer. Debris of different fractions located in the upper layer of water falls into the skimmer basket thanks to the suction action of the pump with which the device is equipped.
The smallest fragments clogging the surface of the pond are captured by a system of high-quality filters. The mixing of water layers that occurs during the operation of the skimmer leads to equalization of temperature, which is a serious limiting factor in the development of algae.
Based on their operating principle, skimmers can be divided into three types:
- with fixed stand,
- free floating on the surface of the pond,
- mounted on the shore of a reservoir.
Cleaning the bottom of the pond
Even with systematic cleaning of the surface, over time a considerable amount of silt will accumulate at the bottom of the pond. You can get rid of it using a special sludge cleaner - a device that works on the principle of a vacuum vacuum cleaner. It draws in everything that is at the bottom - remnants of algae, debris, bottom silt.
An important condition is that the suction pump can only be used in ponds with a concrete or film coating.
UV filters
An ultraviolet filter has a completely different principle of operation - under the ultraviolet radiation it emits, single-celled organisms and algae die, stick together into lumps, which are easily retained by a mechanical filter operating in a reservoir. The result of UV operation becomes noticeable after about a week, the water becomes much clearer and cleaner, in addition, pathogenic microbes dangerous to fish die in it.
Such a filter is installed outside the water; it can be used to clean a reservoir whose capacity does not exceed 230 thousand liters. The service life of a UV lamp reaches from 8,000 to 10,000 hours; its installation and operation are not particularly difficult. Different models differ:
- installation method,
- operating rules,
- power,
- dimensions.
Not long ago, another device appeared that allows you to quickly get rid of small algae. The death of blue-green filamentous algae causes water ionization, caused by current pulses emanating from the microprocessor to a mineralized copper anode and stainless steel cathode. This type of ionization is completely safe for animals, people, fish and plants. The I-Tronik device can be used in reservoirs with a volume of 5-75 thousand liters.
Multi-chamber filtration systems for ponds
Multi-chamber filter systems are popular: among the many models, it is easy to find ones that can be used for reservoirs of different sizes, inhabited by algae or fish. Such devices purify water in three stages:
- remove mechanical impurities,
- treated with ultraviolet light,
- remove biological components.
- ultraviolet radiation will kill, but will not remove algae from the water,
- If the biological filter operates alone, heavy loads will result in frequent clogging.
Since multi-chamber filters consist of several chambers, the water along its route passes through the membranes that separate them and is cleaned of various types of impurities. Dirty, organic-enriched water, which is removed through the filter drain pipes, can be used for irrigation or fertilizer. The purified water is immediately returned to the pond.
In practice, pond filtration systems turn out to be more effective in which, at the first stage of treatment, water enters a round filter chamber - the flow moves slowly and most of the dirt settles in the mud chamber below, then the purified flow passes through the filter mats.
For the normal functioning of the system, it is very important that the pump has optimal performance; too powerful a pump causes water to overflow from the filter, therefore reducing the efficiency of the system.
No less relevant are multi-chamber filters that include UV, disinfection and biopurification. The number of chambers in them should correspond to the volume of water and the presence of fish and vegetation in it. Such systems are small in size and easy to assemble and maintain.
Filtration of pond water using containers
The most natural method of filtration can be considered the use of special containers. The principle of water purification in them is the passage of liquid through a layer of gravel. The use of zeolite or lava granulate can significantly improve the efficiency of the treatment system. The amount of mineral substance is taken at the rate of 3 kg per 1 cubic meter of liquid.
The cleaning process is completed by cattails or other marsh plants planted in baskets on the top layer of gravel. Such a system is installed either in the bed of a stream or at the very edge of a pond - clean water must flow back into the reservoir. To circulate water in such a system, it is sufficient to use a pump with a capacity of about 3-4 thousand l/hour. Do-it-yourself pond filtration, equipped in this way, will work quite effectively.
Pressure filters
The simplest and most economical solution to the problem of pond filtration are pressure filters. This three-stage filtration system can be used for ponds with a capacity of up to 20 thousand liters. Professional pond care is provided by a three-stage system, including:
- UV cleaning,
- biological treatment,
- mechanical filtration.
Such systems have the following advantages:
- they are easy to install and maintain,
- when using a pressure filter, the source of a stream or waterfall can be located above the installation site of the filter; the difference should be calculated according to the parameters of the model used,
- the filter can be integrated with a water heater,
- The filter can be installed by burying it three-quarters of the way into the ground (both of its valves are located directly on the lid) - with this installation option, the task of masking is greatly simplified.
- When choosing a filter for an artificial reservoir, you should take into account many important factors; before purchasing, you should study in detail the characteristics of the selected model and consult the manager of a company that sells filters about the advisability of choosing it specifically for your conditions.
- The filter size should be determined taking into account the fact that improving water quality will lead to more active growth and an increase in the number of fish in the pond, i.e. for a reservoir in which fish live, the volume of the pond should be doubled, the result should be used in calculating the size of the filter.
- Experts recommend taking into account the importance of oxygen saturation of water and using aeration pumps in filtration systems, or installing waterfalls or cascades along the water path.
- Pumps should be selected carefully, taking into account the technical characteristics of the filter; it is better to give preference to models designed for dirty water. The pump should be installed in such a way as to ensure water circulation over the entire area of the reservoir.
- Filters are turned on in the spring, when the water temperature reaches +12 C, and turned off in early autumn, taking into account weather conditions. The filters must operate continuously and should only be turned off for the cleaning period.
- In order to save money, you can adjust the water flow in the system using valves or rotation speed regulators - this will help avoid the system running idle or overflowing. Thin hoses should not be used as they will cause loss of pump performance.
- Masking of filtration systems can be done using stones of different types, differing in beautiful color or original shape.
For the healthy life of all living things, clean water is necessary. Animals will not drink musty, dirty water; they look for sources of clean drinking water. Inhabitants of natural reservoirs can swim away from a polluted area to a cleaner area. It’s harder for fish and other living creatures that inhabit an artificial pond that is not cared for carefully enough. Various debris gets into the water, in the form of leaves, twigs, dust and other things, which pollutes the pond. In addition, waste products of fish and fallen parts of aquatic plants remain in the reservoir. All this rots and falls to the bottom as dirty silt. It actively develops harmful bacteria and fungi. This whole process greatly reduces the amount of oxygen in the reservoir.
An excess of fish in the pond, a lack of plants, as well as rainwater lead to the appearance of a large amount of nutrients in the pond, due to which small green algae grow rapidly on the surface of the water. In the process of decomposition of such algae, putrefactive bacteria actively participate, which also begin to actively multiply and consume significantly more oxygen. Accordingly, there is too little oxygen left in the water for the normal life of fish, ornamental plants and the entire pond as a whole. This condition of the reservoir can cause diseases in both fish and plants, which will lead to unexpected costs for their treatment or even replacement.
If you love your pond and its inhabitants, do not allow water pollution that disrupts the normal natural balance. Use biological agents for this, as well as water filtration systems.
To choose a filter that is suitable specifically for your pond, you need to know its size and the ratio of the number of fish and plants to the volume of water in the pond.
Filtration systems for ponds are usually quite large, so it is advisable to think about their location and installation when designing the pond. It is very difficult to install a filter into a finished decorative pond without disturbing the design of the recreation area.
Your artificial pond will exist as a natural one, created by nature, with its own ecosystem, if you have a properly selected and installed filtration system.
Means to combat algal blooms in artificial reservoirs
Currently, numerous products have been developed and produced for purifying water from small country ponds. With their help, you can get rid of flowering in a pond without harm to ornamental plants and living creatures. It is enough to use these remedies periodically, only when a problem arises. Depending on what you want to improve in your pond, different products are used. You can not only remove harmful algae, but also neutralize ammonia and increase the amount of oxygen in the water. If the dosage is carefully observed, these products do not harm either the biological system of the pond or the surrounding area. After use, they break down into carbon dioxide and water. When using these drugs, it is necessary to ensure water circulation to maintain a normal pH level and better oxygen saturation of the water.
In large ponds with a significant volume of water, such drugs are ineffective. They are used to prevent pollution of a reservoir, and as an additional purification of water before turning on a complex filtration system, which is equipped with large ponds.
Natural minerals – zeolites – are used to purify water in ponds. They absorb harmful substances, preventing water pollution. This quality of zeolites is based on the porous crystal structure. To ensure the normal biological condition of the pond for the entire summer season, you will need only 1 - 3 kg of mineral per 1000 liters of water. Zeolite is placed in special nets and lowered into a pond.
Mechanical filters to protect against large and small debris
A mechanical filter is a lattice container in which a porous sponge is placed or special granules are poured. Water passing through the filter is cleared of sand, small stones, algae and plant debris that get stuck in the sponge or granules. Such filters are used to protect pumps in fountains, as well as in filtration systems for decorative ponds for preliminary cleaning.
Skimmer – a device for cleaning the water surface
On the plot of land, the pond is surrounded by green spaces. Leaves, twigs, seeds and other small debris from them are blown by the wind to the surface of the water. If it is not removed, all the garbage settles to the bottom and rots, forming silt. The water stagnates, its upper part overheats in the hot sun, while light does not penetrate to the muddy bottom, and the water becomes cold. This condition of the pond is dangerous for the health of its inhabitants.
A water surface filter – skimmer – can help your pond avoid this condition. This device sucks up debris floating on the surface of the reservoir, which has not yet had time to get wet and sink to the bottom. When the pump is turned on, the entire surface layer of water begins to move towards the upper part of the skimmer, which floats freely on the surface of the pond and draws in water and debris. First, the dirty water passes through a basket, in which the largest debris, such as twigs, leaves, wood chips, etc., gets stuck. Then it goes into a filter, which purifies the water from the remaining small debris. The skimmer not only purifies the reservoir water, but also improves its circulation. The upper, sun-warmed layers of water, passing through the filter, sink to the bottom, displacing the lower cold water to the top. Thanks to the skimmer, the water in the pond becomes clean and mobile, which prevents the formation of duckweed on its surface.
Skimmers are available in three versions. The skimmer, the upper part of which floats on the surface of the pond, is in no way affected by fluctuations in water level caused by either heavy rain or dry weather. Another skimmer is installed on the bottom using a stand. Small stones are poured into the rack to fix it well. The top of the skimmer protrudes above the water. This type of skimmer is equipped with an automatic adjustment device when the water level changes within 16 cm. A skimmer on a stand is installed in reservoirs with a depth of at least 80 cm. The third version of the skimmer is a side skimmer. It is placed on the edge of the pond. A special feature of this skimmer is the need for a separate pump.
If you have a small pond, for example from an old bathtub, you can simply clean it with a net.
At the bottom of any open reservoir, sooner or later, silt forms from garbage that has rotted in the water. It needs to be removed. To do this, use a special device - a sludge extractor. It can be compared to a home vacuum cleaner. The difference is that the suction pump is much more powerful and serves to suck up not dust, but water with silt, debris, and the remains of the life of pond inhabitants and plants that have settled to the bottom. The sludge pump is suitable for use in any artificial reservoirs with a hard surface.
Ultraviolet filters – protection against organic compounds
Filters based on ultraviolet radiation help protect pond inhabitants, including fish and plants, from various diseases. They can be used for fairly large reservoirs, the volume of which reaches 230,000 liters. Such filters are installed outside the reservoir. Ultraviolet rays have a detrimental effect on harmful algae and microorganisms, which, after treatment, are collected in small lumps. These lumps are easily collected by a biomechanical filter, which is best installed next to the ultraviolet filter. By installing this type of pond cleaning, you will see results within 5 to 10 days. The water will become clear, plants and fish will look healthy.
The advantages of ultraviolet filters include ease of assembly. They are equipped with connectors for all types of hoses. The lamps have a service life of 8000 – 10000 hours. Once the filter is installed, it does not require special care. Many companies produce ultraviolet filters for ponds. The principle of their operation is the same, but there are differences in design, power, and installation method. German ultraviolet filters are especially valued. They differ in that they are equipped with a built-in tube cleaning system, which operates automatically or using an electromagnet. This system protects the UV filter lamp from contamination, which increases the efficiency of irradiation and extends the life of the lamp.
T-Flow – anti-algae devices
T-Flow is a device consisting of a microprocessor, an anode and a cathode. The anode is made of mineralized copper alloy, and the cathode is made of stainless steel. When the microprocessor creates electrical impulses, copper ions are produced, which kill thread algae and other types of harmful algae. This device has no effect on other plants, as well as people and animals, since the amount of copper ions produced is very small. T-Flow devices come in various modifications. They are used for medium and large reservoirs.
Application of multi-chamber filter systems
A lot of multi-chamber filter systems have been developed. You can choose a system that suits your pond. To do this, you need to know the volume of your pond, its purpose, what plants you will plant in it and in what quantities, and also decide whether fish will live in the pond. All of these factors influence the choice of a multi-chamber filter system.
The multi-chamber system consists of three types of filters assembled in one housing. The body is made of fiberglass or polyethylene. These materials tolerate low temperatures in winter and ultraviolet rays in summer. To ensure that the water is completely clean and transparent after purification, three stages of purification are carried out. First, ultraviolet irradiation of the water is carried out, after which lumps of dead algae and microorganisms are formed. These lumps, as well as debris from the reservoir, are drawn into a mechanical filter by a pump. This is how mechanical cleaning occurs. After this, biological filtration of water is carried out. Each filter alone cannot fully clean the reservoir. Ultraviolet destroys algae, which remain in clumps in the water. Therefore, there is no way to do without a mechanical filter. The biological filter is not suitable for cleaning water from large debris. Therefore, all three filters combined are most effective.
Center Vortex multi-chamber filters
Center Vortex filters include several chambers with filters, each of which is designed to purify water from a specific type of contaminant. Water enters the mud chamber from below, where the largest amount of debris is retained. The water then passes upward through the filter media. At the top it flows over the edge of this filter chamber into the next chamber. After the last chamber, clean water flows back into the pond through the drain pipe located in the upper part of the body. The contaminants that collect in the lower part of the chambers are removed through drain pipes into the sewer system or, together with dirty water, are used to fertilize and water the summer cottage.
Features of the vortex chamber
If there is a round vortex chamber at the beginning of the filter system, then this is a big plus for it. As a result of the rotation of water along the inner walls of the chamber, the bulk of debris and dirt falls into the lower chamber to collect sediment. Therefore, significantly purified water enters the filters, which extends their service life. In these systems, it is very important to choose the right pump for your filter. If the pump is too powerful, water will flow faster than necessary. As a result, the filter chambers will be filled with water above the required level, which will affect the quality of filtration.
These filtration systems use pumps of lower power than other systems, so they can be considered more economical, since all filters are constantly running and consume a lot of electricity.
Distinctive features of BIOTEK filters
BIOTEK multi-chamber filters carry out ultraviolet irradiation and biological purification of pond water. It is important to choose the right system specifically for your pond, since the set of filters in it depends on the size of the pond, the presence of plants, fish and other features in it.
The positive qualities of these filter systems include relatively small dimensions, convenient and uncomplicated connection of various types of filtration, which greatly facilitates the maintenance of the system. The disadvantage of some common models of these filters is the low drain hole, which makes it difficult to disguise. The latest filters do not have this drawback.
Systems with pressure filters
If your pond is small, up to 20,000 liters, it is better for you to purchase a filtration system with a pressure filter. It includes all three types of purification - ultraviolet, mechanical and biological, which will provide you with high-quality filtration of water in the pond and protect its inhabitants from diseases. These systems are easy to use and economical.
- Buy a pressure filter and get:
- Professional water purification in three stages using a pressure filter;
- Filter with ultraviolet lamp;
- Convenient and easy operation of the unit;
- Possibility of creating a cascade above the place where the filter is installed;
- Possibility of including water heating in the filtration system (Druk filter system);
- The filter can be easily masked, since it can be buried up to the lid in the ground (water pipes are on the lid).
Please note the following notes:
All information about filters described above is intended as an overview. To responsibly choose a filter system, you need to take into account more detailed features of the reservoir, its qualitative and quantitative characteristics.
If there are fish in the pond, selecting a filter based on power and volume becomes more complicated. It is necessary to take into account that in good water the fish will multiply intensively. Therefore, when calculating a filter for a fish pond, the volume of water in your pond must be doubled.
For the normal state of the ecosystem of a reservoir, sufficient oxygen content in the water is essential. To achieve this, use aeration pumps in filtration systems, create decorative waterfalls that will saturate the water with oxygen and decorate your pond.
In order for the filtration system installed in your pond to be durable, work smoothly and efficiently, you need to pay special attention to the choice of pump. It must be selected based on power and other technical data that are suitable for the filter you are installing. Small solids should pass through the pump easily without clogging it. The pump must be placed in such a place in the reservoir that all the water gets into its area of action.
Filters in open reservoirs operate constantly throughout the warm season. Switching on is carried out at the beginning of the season, when the water temperature is not lower than 12 degrees. Shutting down is possible in the fall, when it gets cold enough. It is allowed to turn off filtration systems during the warm season for cleaning.
The water pressure in the filtration system is determined by various factors: the size of the hose, the number and diameters of connecting elements, the presence of an ultraviolet emitter and other reasons. To prevent water from overflowing from the top or, conversely, there is not enough water for the pump to operate efficiently, the water pressure must be adjusted. For this purpose, valves or speed controllers are used.
After familiarizing yourself with all the properties, advantages and disadvantages of various filtration systems, you may decide to independently choose the appropriate system for your pond. We recommend that you contact a specialist who has knowledge and experience on this topic.
Filtration systems and electrical equipment do not decorate the landscape of a summer cottage. You have to disguise them using your imagination. These can be picturesque artificial stones, sculptural compositions or green spaces.

Animals will not drink musty, dirty water; they look for sources of clean drinking water. Inhabitants of natural reservoirs can swim away from a polluted area to a cleaner area. It’s harder for fish and other living creatures that inhabit an artificial pond that is not cared for carefully enough. IN...Near the house [email protected] Administrator Near the House
