How does a plant filter work in a swimming pond?
A plant filter is a shallow marsh area adjacent to your swimming area. Water flows through the substrate, where filter plants absorb nutrients. This naturally purifies the water without the use of chlorine or UV light.
Step 1: Setting up the filter zone
The filter zone is a shallow area (10 to 20 cm deep) next to your swimming pond. First, lay down the STEP ONE here to serve as the filter bed. This porous material provides a base where bacteria can colonize and plants can take root.
- ✓Shallowzone, 10–20 cm deep
- STEP ONE as filter media
- ✓At least10–15% of the pond’s surface area
- ✓Separatefrom the swimming area
Step 2: Add filter plants
Plant the individual cuttings directly into the substrate. Place the plants in baskets at the desired depth. The combination of marsh plants and oxygenating plants ensures the most effective filtration. Each plant has its own role in the purification process.
- ✓Looseplugs placed directly in the substrate
- ✓Plant in potsat a depth of 10 to 20 cm
- ✓Marshplants filter nutrients
- ✓Oxygen-producing plantshelp control algae
Step 3: Nature does the work
After 6–8 weeks, the plants have taken root and the filtration process is in full swing. The bacteria in the substrate break down waste, the plants absorb nutrients, and the oxygenating plants keep algae under control. The result: crystal-clear swimming water without any mechanical equipment.
- ✓Visible results after6–8 weeks
- ✓Nochlorine, no UV, no pump
- ✓Clear water year-roundwith proper maintenance
- ✓Safefor people, plants, and animals
Common mistakes with swimming ponds
Many owners of swimming ponds face the same problems. With the right approach, you can avoid these mistakes.
Lava instead of Pond substrate
Many landscapers recommend lava as a filter medium. However, lava has a structure that is too coarse, preventing plants from rooting properly and hindering the optimal establishment of bacteria. STEP ONE has been specially developed as a filter medium: it is porous, has the right grain size, and provides an optimal environment for plants and bacteria.
Plants from the garden center
Plants from garden centers are often Grown potting soil and are not suitable for a plant filter. Our plants are specially Grown pond use: they are hardy, rooted in clay, and ready to be placed in the water right away. The difference in growth and filtering performance is enormous.
Not enough plants for the space
A plant filter only works if there are enough plants for the volume of water. Too few plants means insufficient filtration, which leads to algae and cloudy water. Our kits are precisely tailored to the filter size, so the system works optimally right from the start.
Proven results in real-world applications
Owners of swimming ponds notice a difference after just a few weeks with a well-designed plant filter.

How does a plant filter work?
A plant filter is a shallow marsh area next to your swimming pond. The water flows through the substrate, where filter plants absorb the nutrients. This naturally purifies the water—without a pump, without a filter, and without chemicals.
- ✓Filter plants remove waste from the water
- ✓Oxygen-producing plants compete directly with algae
- ✓The substrate provides a habitat for bacteria to break down organic matter
- ✓Result: swimming water without chlorine or UV treatment

A little paradise for frogs
I really wanted native plants to help support the local ecosystem. This package is fantastic. Everything is growing like crazy, and after just two months, I already had salamanders and frogs in the pond. The water is crystal clear.
