Pond filtration system without the need for constant sponge cleaning and pressure filters
The CrawTec FS 20–30 m³/h pond filtration system has been developed as an alternative to domestic pressure filters, which quickly become clogged and require constant maintenance. Many ornamental and koi ponds use compact filters with sponges or scrubbers, which need to be rinsed daily. When the load increases, such filters can no longer cope with the cleaning, the water becomes cloudy, and sludge begins to accumulate at the bottom.
The pond filter in this series solves this problem by using mechanical drum cleaning and a separate biological filtration unit with integrated UV lamps. The system is supplied as a ready-to-use kit, with the drum filter and biofilter factory-connected. This allows for comprehensive water filtration in the pond without the need to select individual components or carry out complex adjustments.
This pond filtration system is particularly relevant for owners of ornamental ponds and koi ponds who face typical water pollution problems. When switching from a domestic filter to a drum system, the amount of mechanical debris is reduced, water parameters are stabilised, and the need for manual maintenance is significantly reduced.
The drum filter for ponds as a replacement for pressure systems
The main component of the system is the drum filter for ponds, which performs automatic mechanical water purification. Unlike sponge filters, where contaminants accumulate inside the housing, the drum removes them directly from the system. This prevents the decomposition of organic matter and reduces the load on biological filtration.
When using pressure filters, pond owners most often face the same problems: the water remains cloudy, the filter clogs quickly, and the sponges have to be rinsed several times a day. As a result, pond filtration becomes unstable, and water quality depends on the frequency of maintenance. Mechanical drum cleaning eliminates this factor and ensures consistent system performance.
Using a drum filter for a pond is particularly effective where fish are present. Uneaten food, suspended particles and organic matter are removed before reaching the biological unit. This allows the pond water filtration system to operate consistently even under increased load.
Pond biofilter with integrated UV water purification
After mechanical filtration, the water flows into the biological filtration unit. The pond biofilter processes dissolved pollutants and stabilises water parameters. A colony of beneficial bacteria develops in the filter media, which breaks down ammonia and fish waste products. This is particularly important for ornamental and koi ponds, where stable water filtration is required.
Additionally, the system is equipped with integrated UV lamps. UV treatment reduces algal blooms and decreases the amount of suspended algae. As a result, the pond filter not only provides mechanical and biological purification but also improves water clarity. This combination makes the system a versatile solution for private ponds.
Combining biofiltration and UV treatment in a single unit results in a compact pond filtration system. This simplifies installation and makes the equipment convenient to install next to the pond.
For which ponds is the 20–30 m³/h filtration system suitable?
The CrawTec FS 20–30 m³/h pond water filtration system is designed for ornamental ponds, garden ponds and koi ponds with a moderate biological load. The kit allows you to replace domestic filters and switch to a more stable water purification system. Thanks to automatic mechanical cleaning, there is no need for daily maintenance.
This pond filtration system is particularly effective in cases where owners are faced with the constant cleaning of sponges and unstable water clarity. Once the drum filter and biofilter have been installed, the system begins to operate as a single integrated purification unit, and water quality becomes more predictable.
The system can be used in the following types of water bodies:
- ornamental garden ponds with water circulation
- small and medium-sized koi ponds
- private ponds with fish
- upgrading existing filtration systems
- replacement of pressure filters with sponges
Under such conditions, the pond filter ensures stable water purification and reduces the accumulation of organic matter. This allows for reduced maintenance frequency and improved water clarity.
Ready-to-use water filtration system for ornamental ponds
The CrawTec pond filtration system is supplied as a ready-to-use kit, including a drum filter and a biofilter with UV. This solution eliminates the need to select individual components and ensures stable operation of the equipment. All components are designed for joint operation and are connected as a single treatment line.
A pond filter of this configuration can be used as the main filtration element in ornamental and koi ponds. Mechanical and biological treatment operate in sequence, ensuring consistently clear water and reducing the maintenance burden. This is particularly important for private ponds, where reliable filtration is required without the need for daily cleaning.
The use of a drum filtration system allows you to move from simple DIY solutions to a fully-fledged water purification system. As a result, the amount of contamination is reduced, water parameters are stabilised and the reliability of the pond’s operation is improved.
