Equipment for ponds and reservoirs

To keep the water clean, transparent and healthy, it is necessary to ensure its circulation, oxygen saturation, cleaning from garbage and harmful organisms and to organize the processing of harmful substances in water into safe compounds. Besides, you can also decorate a pond with a small fountain, build a beautiful full-length waterfall, a cozy creek or all of this together, but also correctly illuminate all this beauty. To do this, you will need to pick up properly all types of equipment for ponds and reservoirs, which is divided into groups corresponding to its purpose.

Filters for ponds

The selection of necessary equipment for the pond should start with the filtration system. The correct selection of the type of filtering system and its efficiency will serve as a guarantee of the health of your reservoir and its inhabitants. It should be noted that there are many different systems for treating stagnant water, and if one submersible filter with a pump is enough for a tiny decorative pond, then for a large pond with fish, a combination of all types of filtration systems will be required. The filter is selected to circulate the entire volume of water in reservoir through the filter in 2 hours.

Submersible filters

are used for small decorative ponds, which do not have fish, and represent a simple mechanical filter to protect water from garbage particles in water. Submersible filters usually consist of filter in a single body with a pump and equipped with fountain nozzles to decorate the reservoir with a small fountain. Often, manufacturers install ultraviolet sterilizers of low power into submersible filters.

Pressurized filters

for ponds represent a sealed container with filtering materials, water in which is under pressure. They are used in small reservoirs, both with fish and without, especially if you need to put water on a waterfall, mountain or creek. In pressurized filters, a combination of a mechanical and biological cleaning method is commonly used and there are a built-in ultraviolet sterilizer in many models of pressurized filters.


filters are installed on the shore of small reservoirs with or without fish, so that water flows out of the filter directly into the reservoir under the influence of gravity and it is pumped in the filter with pond pumps. Such filters are a mechanical and biological filter in one body. As filter materials, special sponges for mechanical cleaning and mats for biological cleaning are used. In addition to the frequent built-in ultraviolet sterilizers, some manufacturers equip such filters with a metal mesh and other additional functions.

Sieve filters

serve for preliminary mechanical cleaning of water and a special stainless steel mesh with a cell size of 50-300 microns is used as the filter material. Such filters are used in medium and large bodies of water, as well as in fish farms. They are able to provide a substantial flow of water and since they provide only mechanical filtration, they are always used in combination with a biological filter. A minor disadvantage of such systems is the need for frequent maintenance.

Drum filters

are currently the most advanced and efficient systems for mechanical water treatment. In drum filters, as in the sieve filters, a stainless steel mesh is used as the filter element, but in this case, it is in-built in a rotating drum. This design is used to automate the cleaning process. The drum filters are rinsed automatically and do not require any intervention to maintain it. To clean the filter drum from the growing of bio-membrane, built-in ultraviolet sterilizers are often used. Such filters serve as the basis for creating a powerful and automated filtration system and are usually used in combination with biological purification systems.

Biological filters

serve to purify water from harmful substances and waste products of pond inhabitants with the help of bacteria. With the help of biological filters, dangerous ammonia contained in water is processed into nitrites, and those in turn into safe nitrates. The most common, effective and popular biological filters are filters with moving biological filter media. Bio media is set in motion by air and serves as a home for beneficial bacteria. Bio-filters with moving bio media are always used in conjunction with other filtration systems to ensure the optimum quality of water treatment.

Shower filters

can be identified as a separate group of filters, although in fact they are one of the types of biological filters. Such filters do not require the use of aerators to saturate the water with oxygen, as it breaks up into small sprays and irrigates the bio filter media placed by the tiers. Optimal oxygen saturation is achieved with this method of water flow and an imitation of a natural method of water purification in high-mountain springs is created.

Combined filters

are systems of two or more different types of filters assembled in one body. Combined filters are usually based on drum or sieve filters. The first stage of purification in combined filters is mechanical, and the second is biological purification. Combined filters also include modular filtration systems, in which the system is built of several independent modules, interconnected by flexible, rubber connections.

Ultraviolet Sterilizers

Ultraviolet sterilizers are used in all kinds of ponds and reservoirs, including fish. Sterilizers with ultraviolet radiation disinfect and purify water from viruses, bacteria and even fungus. The use of sterilizers is necessary if you want to see the water in the pond clean and transparent. In doing so, it must be remembered that the resource of effective work of the ultraviolet lamp is limited and it is recommended to change it at the beginning of each season.

Pond pumps

It is impossible to imagine a decorative pond, even the tiniest, without a pond pump. Even in ponds with gravity filters, pumps are used to pump water from the filter into the pond. Moreover, pump provides circulation of water in pond, at which the layers mix with each other. Pumps supply water to waterfalls and fountains, with the help of pumps streams flow and filters work. Thus, the pump is truly the heart of any water body. It is important to choose the pump of the required capacity to ensure sufficient flow of water through the filter and other connected equipment, and in some cases, you can use two or more pumps. It is important to remember that pond pumps are designed for continuous operation and consume very little power, but they do not create pressure.

Skimmers for ponds

Pond skimmers perform very necessary work of collecting floating debris in ponds. Such storages of fallen leaves, small branches, remnants of floating plants prevent the settling of such debris on the bottom and its further decomposition with release of harmful and toxic substances into the water. Skimmers are of several types: stationary ones – they are built in the shoreline at the stage of its construction, skimmers on the stand – are installed on a special stand in any convenient place in the pond, floating skimmers – freely move over the entire surface collecting garbage. The debris in the skimmers accumulates in a special basket and during maintenance this basket is cleaned by hand.

Aerators for ponds and reservoirs.

Aerator is a device that is used to saturate water with oxygen, pumping air through it. The aerator consists usually of two parts – an air compressor that pumps air and an aeration element (atomizer), this air is sprayed in water in the form of bubbles. It should be remembered that the smaller the bubbles of the sprayed air, the more efficient the saturation of water with oxygen. With the help of aerators, the bio filter media in the biological treatment units is set in motion, and in winter, the bubbling water does not freeze, forming holes. Aerators help to circulate water in the pond and increase the efficiency of the beneficial bacteria, stimulating their growth.

Lights for ponds.

Lights are used to organize decorative lighting in ponds, fountains, waterfalls, water slides and other garden objects. With the right selection of fixtures and a creative installation of such equipment, the pond can completely transform in the dark. All pond lamps are protected from water and moisture, and most can be installed at shallow depths under water. In addition, they are often equipped with light-sensitive sensors that automatically turn the illumination on and off when the outdoor illumination level is changed.
