Why a pressure filter is the right choice for you:
A pressure filter is characterised by its compact design and closed-system architecture. With the help of a pond pump, water is forced under pressure through various filtration stages. The major advantage of this is that the purified water can be easily redirected to higher-positioned water features or watercourses. Since these filters are highly flexible and can be installed almost invisibly if required, they are perfectly suited for:

  • Ornamental ponds and small to medium-sized garden landscapes.
  • Ponds where there is only limited space for technical equipment.
  • Ponds with moderate fish stocking levels or a watercourse element.

Tips for operation and regular maintenance:
To guarantee permanently stable water parameters in your pond, you should run the filter in continuous 24-hour operation throughout the entire season. This is the only way to keep the biological filtration active. As the weather turns colder, you can reduce the intensity or winterise the system, depending on your region and the depth of the pond.

Regular maintenance is essential to ensure filtration performance remains high. Depending on the biological load and fish stocking levels, plan to clean roughly every 2 to 6 weeks. Please note that cleaning more frequently is necessary during the height of summer due to the intense summer sunlight as compared to the shoulder seasons.
