Purifies the water

The roots and leaves of pond plants absorb waste products from the water.

Plant filter as a natural water filtration system in the pond

To optimally purify a pond, a good plant filter important, combining the right types and amounts of pond plants. It is important to use the right pond substrate so that the plants can adhere well to and within the substrate. In addition, oxygen plants such as hornwort, crabgrass and waterweed should be added to properly purify the pond.

Summary of the YouTube video: "Wetland Filtration for Pond Health" by Ed Blue from Aquascape

In this YouTube video, Ed Blue of Aquascape discusses the concept of wetland filtration, which mimics the natural process of filtering toxins from water through wetlands. The wetland filter consists of a snorkel and centipede module to slow the velocity of water and settle sediments at the bottom. Aquatic plants and pond substrate in turn remove nutrients and create a living ecosystem that requires high levels of dissolved oxygen. The size of the wetland filter can be adjusted according to the volume and pollution of the water. The video provides a step-by-step guide on how to create a natural plant filter for all kinds of types of ponds or water features.

Your contribution to the environment and biodiversity through a plant filter in the pond

In this YouTube video, Ed Blue of Aquascape discusses the concept of wetland filtration as a natural and effective way to purify water. Wetlands are known as the "kidneys of the earth" and filter toxins from the lifeblood of the earth, which is water. A wetland filter is a type of filter used in ponds to naturally keep water clean. The filter causes the water to flow slowly so that dirt and sediments sink to the bottom and can be easily removed. The filter also has aquatic plants and substrate that remove nutrients from the water, keeping the pond clear and clean. Aquatic plants play a crucial role in the pond's purification process because they absorb nutrients produced by algae and other pollutants in the water. This reduces the ability of algae to develop and keeps the water clearer and healthier. In addition, pond plants provide oxygen to the water, which is essential for maintaining a healthy and balanced ecosystem. Using a plant filter is a sustainable solution for purifying water because it does not place a burden on the environment. It is a completely natural solution and can be adapted to the specific needs of the pond. By improving water quality using a plant filter, pond owners can create a healthy and aesthetically pleasing ecosystem that helps maintain biodiversity.

Wetland filter researcher: Ed Blue of Aquascape

Ed Blue is a representative of Aquascape, a company that specializes in designing and building water features and ponds. In the link video, he discusses the concept of wetland filtration and offers a step-by-step guide on how to build a wetland filter/natural plant filter for ponds or water features.

Pond specialist and naturalist: Simon van der Velde

Since 1986 Simon van der Velde as a pond specialist and helps people realize their dream pond with his company "Van der Velde Water Plants". His vision is to restore biodiversity in the Netherlands, Europe and eventually the entire world, by inspiring people to build a natural pond in their garden. When designing these ponds, he avoids the use of pumping systems and filters, because these are not necessary if the pond is designed in the right way. This way, nature can do its job as it was originally intended.


Advice for a natural swamp plant filter

Buy Plant filter

A plant filter is a natural filter where the plants themselves purify the water without the use of a pump. The cooperation of certain plant species and pond bacteria ensures that harmful substances are broken down from the water and the pond water is purified. For optimal filtration, we offer specially formulated plant filter packages.

Helophyte filter pond

A helophyte is a perennial or biennial plant whose submerged buds alone survive the winter; everything above the water's surface dies off. When a helophyte is too deep below the water table, it can die from lack of sunlight. Well-known helophytes that can be used as a helophyte filter include: yellow iris, calamus and bulrush. In proper composition, helophytes provide very good purification of pond water.

Making plant filters for the pond

A good plant filter is a combination of the right species and quantity of pond plants. For optimal purification, use the right pond substrate (so the plants can attach well to and in the substrate ) and add oxygen plants, such as hornwort, crabgrass and waterweed. Learn all about a plant filter in the pond.

Biological swamp filter pond

A plant filter or swamp filter is a natural filter where plants and bacteria provide water filtration. Some plants are helophytes, that is, perennials where only the buds survive under water during the winter.

An organic pond or natural pond requires little maintenance and has minimal environmental impact. This is because pumps and filters are unnecessary in it, as the aquatic plants provide a natural balance. An organic pond is a pleasant place for insects and amphibians.

Natural filter build yourself in the pond

When building a natural filter, there are a number of factors to consider. The first is where you are going to build the pond. Plants grow best in a sunny spot. To keep the water from heating up too much, water lilies are an excellent solution. The large leaves of the water lily ensure that the sun has less chance of extremely raising the water temperature. Also, the leaves provide a good hiding place for marine life. Second, the pond depth is important. Provide a depth of at least -80 cm so that fish have the opportunity to overwinter. Third, a bottom of the right substrate is important. In this substrate can grow bacteria that purify the water and plants can easily attach themselves in and to a bottom of substrate. All pond packages include a proper composition of plants and the proper substrate.

Clear water without a filter pump

A pond can remain clear and balanced without a pump or filter when the right composition of plants is present in the pond. These plants, along with bacteria, ensure that the water is purified of pollutants and remains clear and healthy.

A plant filter or helophyte filter provides water filtration. Plants carry oxygen to the roots, where the water is more oxygenated. The supply of oxygen allows bacteria located at the base of the stems to grow well. These bacteria purify the water of pollutants. Marsh plants absorb wastes such as nitrate and nitrite from the water, purifying the water.

For an organic pond, it is important to establish a good marsh zone. Most aquatic plants grow well in depths down to -20 cm. It is important to create a large marsh zone. The larger the zone, the better the water will be filtered. In addition to the size of the zone, the composition of the plants is also important, think marsh plants, oxygen plants and water lilies.

Dig a filter area and lay the pond liner in it. Then apply a layer of substrate of about 10 cm. This is where the marsh plants can be planted. Use enough plants, you will have enough with this natural filter. Then secure the plants with another layer of substrate of about 10 cm. Finally, place the floating oxygen plants, which also keep the sun out of the water. This reduces water heating and inhibits algae growth. Read all the explanations to make a plant filter.

The size of a plant filter is best to be as large as possible. This is because the larger the plant filter, the better the filtration and the lower the water load.

A good plant filter is about -40 cm deep. Most aquatic plants grow well at -20 cm depth.

The top 6 best plants for a natural pond filter as far as we are concerned are: yellow lis, 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.

This depends on the season. In the spring, plants will grow rapidly and during the summer the growth slows down. We allow for approximately 16 plants per m2 in our specially formulated plant filter packages.
