Part I. Pond construction step-by-step plan
By listening carefully to the prospective pond owner, Simon can provide customized advice on how to best design the water feature. But getting started with building a pond yourself is also possible, of course. If you want one with pond liner, follow this step-by-step plan.
Step 1. Determine pond type and proper location
A good start is half the battle. Think carefully in advance about what kind of pond you want and where it will be located. If you dig your own pond, you can do so without a permit. However, you may need a permit for a construction such as a reflection pond. Find this out in advance. Furthermore, a spot in the garden is suitable where there is four to six hours of sunlight a day. This allows the pond, filled with the right plants and bacteria, to maintain a constant temperature and biological balance.
Step 2. Create a floor plan
In the next phase, we recommend making a floor plan and a cross-section of the pond. On this you will indicate the different zones where the aquatic plants will be placed. A pond can contain up to five zones. If you are going for a small pond, keep two to three zones to place plants. The pond should be at least -80 to -100 cm deep. The most important zone is the swamp zone (-10 to -20 cm) where many plants will be placed. Be careful not to make the zones too narrow, because then there won't be enough room to place aquatic plants.
Step 3. Excavating and lining the pond
Good, the dimensions and shape of your pond are determined, the execution can start. Before you start digging, check the groundwater level. Drill a hole at the deepest point of the pond. Will this stay dry? Then you can excavate a pond at that spot. Keep in mind that there will be a lot of soil coming out of the hole that will need to be drained. If the pond hole is ready, then it is time to line it with pond liner. Before you start laying, remove protruding stones and sharp points. Simon recommends finishing the edges by laying stones on top or screwing the liner against a wooden edge.
Step 4. Make sure you have a good pond planting plan.
With a well-developed planting plan, there is no need for a filter or pump in the pond. The natural plant filter, proper bacteria and location together do the job. Water improvers become unnecessary and maintenance is minimal. For a medium-sized pond, pond owners spend an average of €200 to €300 per year on water testing and on KH and GH products, in order to get the water values even. You don't need all this if you use enough and the right aquatic plants. On the map you can indicate where you want to place which plants. In Part II on this page we explain which aquatic plants you need for a healthy pond.

Part II. Setting up a pond in 6 steps
After your pond is dug and the liner is laid, it's time to start decorating the pond. Simon's step-by-step plan ensures that you can enjoy a clear, biologically balanced and low-maintenance pond all year round. All required products are listed by step so you can easily put together your own pond kit.


Step 1
Provide a layer of pond substrate at the bottom of the pond. Apply these porous stone granules in an 8 to 10-inch layer to the bottom of the pond. The bottom is the foundation of the pond, so don't skimp on this. The bottom with pond substrate ensures that any pump and filter need to be cleaned less often, because they are hardly burdened. This is because the substrate acts as one large filter.

Minimum 1.5 bags of 20 liters per m²
Pond substrate
Step 2
Sufficient oxygen plants are vital for natural balance and clear water. They also provide shelter for marine life and block out sunlight. Many oxygen plants take root in the pond substrate and absorb silt. They use this as nutrition so that these aquatic plants grow better.

Simons consulting
Minimum: 5 to 6 loose oxygen plants per m³ ( 1000 liters of water) and 1 basket with 4 plants per m²
Loose oxygen plants
Planting depth pond: 0 to -120 cm
Oxygen plants in baskets
Pond planting depth: -10 to -40 cm
Step 3
It is important to provide the pond with plenty of water lilies. The plant species provides shelter for the fish and other animals present. The water lily foliage also blocks the sun, reducing water heat and algae growth.

At least 1 water lily per 0.5 to 3 m²Â
Large water lilies
Pond planting depth: -20 to -100 cm
Small water lilies
Planting depth pond: -20 to -40 cm
Step 4
Aquatic plants with a good root system will filter the water while reducing the amount of waste in the water. Thanks to our experience, we know exactly which plants work best and are also hardy. We have selected the right species for you.

Step 5
Bog plants also have a function of their own. They absorb waste products, reducing nitrate and nitrite concentrations in the water. In our assortment we have included only the strongest hardy species.

At least 1 basket with 4 plants per 1 m²Â
Marsh Plants
Planting depth pond: 0 to -20 cm
Step 6
Bacteria are added to give a new pond a good start. In addition, an existing pond gets another boost each spring by adding good bacteria. The bacteria attach themselves to the pond substrate present and excrete enzymes that filter the organic particles in the water. Thus, they contribute to clear water
