HEISSNER Pond Filters

For biotopes, garden ponds & compact fish ponds

Pond filters perform a vital function within every garden ecosystem. They ensure crystal-clear water, decompose surplus nutrients, and maintain the biological equilibrium essential for both flora and fauna. The HEISSNER portfolio features high-efficiency pressure and flow-through filters, catering to everything from compact ornamental ponds to high-specification koi habitats. Engineered for permanent outdoor installation, all systems are UV-stable, frost-resistant (with appropriate maintenance), and designed for seamless technical integration with HEISSNER pond pumps.

The functions of a pond filter
A pond filter performs mechanical filtration by removing debris and suspended particles, while simultaneously facilitating the biological degradation of pollutants. This ensures crystal-clear water, suppressed algae growth, and balanced water parameters.

Optimal filter runtime
During the active pond season, the filtration system should operate continuously, 24 hours a day.
Perpetual operation is essential to maintaining stable water values and preserving biological filtration efficacy. Depending on the pond depth and regional climate, the filter may be paused or the flow rate reduced during the winter months.

Pond filter maintenance intervals
Depending on the nutrient load, fish stocking density, and the time of year, maintenance is recommended approximately every 2 to 6 weeks.
During the peak of summer, cleaning requirements typically increase, whereas they tend to subside during spring and autumn.

Overview of filter types

  • Pressure filters: These sealed, compact units offer flexible installation optionsā€”even below the water level. They are the ideal choice for small to medium-sized ponds.
  • Flow-through filters: Open-concept systems designed to handle high water volumes. They are primarily suited for large ponds or aquatic environments with high fish populations.

Key selection criteria

  • Select a filter size appropriate for the total water volume and stocking density of your pond.
  • Ensure the filter's capacity is precisely matched to the output of your pond pump.
  • Guarantee consistently high water quality through regular maintenance and care.

For smaller ornamental ponds, space-saving pressure filters are often the preferred option. For expansive installations or ponds with high fish stocks, you should rely on a high-performance flow-through filter in combination with an appropriately dimensioned pump.
