Frequently asked questions about filter plants
Although the two terms are often used interchangeably, there are some subtle differences. A plant filter is a general term for a filter made of plants that purify water. A helophyte filter is more specific and refers to a filtration system in which helophytes, or Sumpfpflanzen, are used to purify water. Helophytes have the unique ability to purify water by absorbing pollutants in their roots.
The choice of plants depends on what you want to achieve. In our opinion, the top 6 best plants for a natural pond filter are: flag iris, sweet flag, water mint, dwarf licorice, needlewort and parrot feather. These plants can also be ordered from us as a complete package, a plant filter mix of 64 plants, specially formulated for optimal filtration and clear water.
A helophyte filter requires relatively little maintenance. It is important to check the plants regularly and trim them if necessary. Also remove dead or rotted plant parts to keep the filter working optimally. Check the water quality periodically to make sure the filter is functioning properly.
To prevent algae in a plant filter, you can put low-growing oxygen plants among the tall plants. These oxygen plants improve oxygen levels in the water, which helps control algae growth. In addition, they provide shade, which reduces light penetration and thus limits algae development.
The amount of plants depends on the size of your pond and the specific needs of the ecosystem. In general, the larger the pond, the more plants you need. A good rule of thumb is to have at least 12 plants per square meter of water surface, but this can vary depending on the plant species and the specific requirements of your pond.
Loose filter plants, also called plugs, are robust plants that you can place directly in a layer pond substrate . Place these plants in the shallow end of the pond or in the plant filter so that their roots are in the water. This allows them to contribute optimally to the natural filtration of your pond.
Loose plugs that can go down to -10cm deep:
- flag iris (Iris Pseudacorus)
- Blue Lis (Iris Kaempferi)
- Dwarf glade (Typha Minima)
Loose plugs that can go down to -20cm deep:
- Large great reedmace (Typha Latifolia reedmace)
- flowering rush (Butomus Umbellatus)
- Pied sweet flag (Acorus Calamus Variegatus)
- pickerel weed (Pontederia Cordata Swamp hyacinth)
