Integrating a pond in the garden is not rocket science in itself. However, it is more difficult to plan it correctly. There are a few things to consider here.Think carefully about what you want
A pond is really more than just a visual highlight in the garden. Depending on the type of pond, you can also swim or use animals in it. Both are of course a fine thing. Unfortunately, many rush to choose a garden pond. There is no real thought about the equipment or the costs, and your eyes widen when, for example, the fish die in the pond due to a missing filter system or the bill for pond construction turns out to be much higher than expected.
So if you want to integrate a pond in your garden, then you shouldn't rush it under any circumstances. Make sure you have some important thoughts beforehand. Of course, choosing the right size and depth is not everything. There are many more points to worry about. These relate to planning, implementation and cost calculation.
Important points when planning
Design and size of the garden pond:
How expensive a garden pond is depends on your individual wishes. Smaller objects usually cost a few hundred euros, for larger ponds the costs can be in the four to five-digit range. Basically, the pond size primarily depends on the local conditions. To determine the size, you must first clarify what you want to use the pond for. Should it be a near-natural pond, which should serve as a biotope for animals and plants, or should the pond be used for swimming?
Location of the pond:
Depending on the size of your garden, you need to choose the location of the pond. If you want to keep an eye on the garden pond from the terrace or from the living room, then create the water near the apartment or house. If it is to become a near-natural pond that attracts many animals, then it is better to build it a little further away. If the garden is a bit sloping, it is advisable to create the pond at the lowest point, as this looks more natural.
The right ratio of sun and shade is also important: on the one hand, water plants need a certain amount of light, on the other hand, too much sunlight promotes algae growth. For your orientation: five hours of direct sunlight are sufficient. The garden pond should be laid out so that it lies in the shade of a larger tree or building at lunchtime. Trees with a flat root system, e.g. Birch trees, but not near water, as the roots can pierce the pond liner.
Maintain minimum depth:
A pond should not be too small if fish or other living things are to live there permanently. Larger ponds are ultimately subject to lower temperature fluctuations, which is fundamentally better for the ecological balance. It is also important that you pay attention to a minimum depth when creating a near-natural pond so that the animal inhabitants can survive the winter without any problems. As a guideline, you can stick to a minimum depth of 80 cm. This should be enough in this country so that the water doesn't freeze completely. You can of course create a smaller pond without fish.
Install filter system:
If you want to have fish in the water, you also have to be aware that their excretions overwhelm the natural sewage treatment system, and they also eat the natural sewage treatment plant. In this case, the installation of a filter system for maintaining the water quality is absolutely necessary so that the pond ecosystem remains healthy.
2 options for implementation
1. Create a pond using a plastic pool:
The quickest and easiest way are garden ponds made of finished plastic pools. In addition to the simple structure, their robustness is another advantage. On the other hand, the small size sooner or later leads to a deterioration in water quality. This requires continuous maintenance and a general overhaul after a few years. The latter involves changing the water and removing the sludge.
2. Create pond with pond liner:
A little more craftsmanship is required to create a garden pond with pond liner. It is advisable to excavate the floor in a step shape. It is important that the pit has a slope ratio of 1: 3 from the center of the floor to the top. You then have to apply a layer of sand on the redesigned (modeled) surface to compensate for unevenness. If necessary, attaching a protective grille against mice and other rodents is advisable.
The next step is to place a pond fleece on the previous layer before you can insert the pond liner. Lay these as wrinkle-free as possible. You also need to make sure that the edge of the film is facing up to prevent roots from growing into the pond. The cheap material is plastic, the variant with rubber has an ecological advantage. In addition, plastic films give off substances that also get into the water.
When the prefabricated pool is installed or the pond liner is laid out, the construction of the garden pond is not yet complete. Important technical accessories are still missing. This primarily includes the pump and the filter. Which type and size are required depends on the size and the planned use of the pond.
Overview of important cost factors
Choosing the right pump is not easy because it takes on a variety of tasks in the pond. Together with the filter system, a pump on this website ensures that the ecosystem in the garden pond is maintained. Other tasks are the conveying capacity as well as water aeration and circulation. A pump must therefore be of appropriate quality so that it runs as long as possible and ideally requires little maintenance.
It is also important that it does not use too much electricity. So think carefully about what kind of pump you are going to buy. It is definitely worth investing a little more money here. You can save money with a cheap pump model, but they often also consume more electricity. Modern, technically more up-to-date pumps, e.g. are offered at www.amazon.de, so they are cheaper in the long run. I found a good example of how expensive a cheap pump can become over time at www.naturagart.de. It's really amazing how much you have to pay if you really want to save money.
The next important point follows from the previous point: always keep an eye on the electricity costs. In addition to calculating the expenses for the operation of the filter system and the pump, there are also electricity costs for the operation of lamps for pond lighting. So if you don't want to fall over when the electricity bill flutters into the house, I advise you as a pond owner to check the electricity tariff regularly. The easiest way with the usual suspects on the Internet, such as Verivox & Co. (www.verivox.de/stromvergleich).
By the way:
Also plan enough money for decorative items such as Statues, ornamental plants or decorated stones. On top of that, maintenance also costs a lot of money.
