Pond Plants

Filter plants

Simon van der Velde

Filter plants are important for biological balance in the pond. They are especially useful in swamp areas, where they help keep the water clean. You have two types of filter plants: loose filter plants and those in pond baskets. Loose filter plants you place directly in the pond substrate and are good for large swamp filters. Filter plants in pond baskets can be placed either in or outside the substrate. These are often the first choice for smaller plant filters or containers. Thereby, low-growing oxygen plants are a must in the plant filter. Not only do they provide more oxygen to the water, but they also help prevent algae growth. Because they grow low, they cover the shallow water and reduce light, which helps prevent algae growth. In short, for a pond with biological balance, it is important to place both filter plants and low-growing oxygen plants in the right place.

Loose tall filter plants

Loose plant filter plants are placed directly into the pond substrate and are ideal for larger swamp filters.

  • Why. These plants have a natural ability to filter the water, contributing to a clear pond and maintaining the balance of the ecosystem.
  • How many? The recommendation is to have a minimum of 12 individual plant filter plants per 1 m².

Frequently asked questions about filter plants

Pond Advice

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: Sumpf schwertlilie, calamus, water mint, dwarf licorice, needlewort and featherweed. 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.

Other supplies for the pond

Plant filter plant function

The main task of plant filter plants for a helophyte filter and swimming pond is to help purify the water. Pond bacteria play an important role here. Sumpfpflanzen have the ability to transport oxygen to the roots, allowing oxygen-loving bacteria to settle there. In contrast, aquatic plants absorb nitrate and phosphate, which are end products of the purification process. Therefore, it is important to prune plants in the fall and remove dead leaves to prevent excessive nutrients from entering the water.

Plant filter pond

A plant filter is the ideal addition to a swimming pond or normal garden pond. It uses aquatic plants to purify the water naturally, without chemicals. It creates an ecological balance, beautifies the pond and dampens sounds. In short, a plant filter provides effective and natural water purification and creates a harmonious and pleasant environment to enjoy while swimming.

Pond filter plants

Yellow Lis (Iris pseudacorus), Lisdodde (Typha), Calamus (Acorus calamus), Lidsteng (Hippuris vulgaris) and Aarveder (Myriophyllum brasiliensis) are excellent plants for a plant filter. They help filter water, purify it by absorbing excess nutrients and produce oxygen. Their strong growth and filtering properties make them ideal for maintaining a healthy and balanced water environment in the filter.

Filter plants pond

A helophyte filter is suitable for any type of pond. This type of filter uses helophytes, or Sumpfpflanzen, to purify the water. It filters organic matter, nutrients and contaminants from the water, keeping it clear and healthy. Whether you have a natural pond, formal pond, swimming pond or koi pond, a helophyte filter can be customized to the specific needs and size of your pond. It provides a natural and sustainable solution for water purification without relying on chemicals. So whether you have a small ornamental pond or a larger water feature, be sure to consider the benefits of a helophyte filter for effective and ecological water purification in your pond.
