Regardless of the indisputable statement that a waterfall in the garden pond is one of the most beautiful design elements that visually enhances the oasis of calm enormously, the splashing water brings another very practical one Advantage. With the bubbling water, the oxygen supply and its quality improves significantly and even the smallest Stream already ensures a better biological balance in the pond.

Size and effort
While the financial outlay for the self-built waterfall at the garden pond will not cost immense sums preparing the watercourse and making it as natural as possible are a little more complex in terms of time. Even if it is the size of the garden plot and the of the pond If possible, plan your waterfall at the pool in such a way that disturbing noises for the fish stock and the neighboring properties are kept to a minimum. Several small, not too steep gradients are more labor-intensive, but look particularly attractive with natural lines.
Location for the self-built waterfall
Commercially available brook bowls can be used as storage containers for the water flowing down into the valley. Such tanks are usually made of sturdy plastic and are already equipped with the necessary inlets and outlets, sometimes even with pumps and the associated water filters. The size of the storage container you require depends (among other things!) On how far the line is in the pond and whether you want your waterfall to run continuously or for a limited time flows. Depending on the funding height and depending on HOW, i.e. in which form the cool water should splash along, the system needs a certain and not insignificant water supply, which our table in liters shows:
| Delivery head (cm) | 30 | 50 | 60 | 100 / 125 | 150 / 200 | 250 |
|---|---|---|---|---|---|---|

The optimal pump size
In addition to the size (length, width and depth) of the course of the stream and its terrain-dependent routing, the volume The brook shell also includes the required design and performance of the feed pump in the planning of the waterfall flow in. If the installation of cascades in the water supply is also desired, a considerable amount of water is generated relatively quickly, which demands maximum performance from the pump. Even with a low delivery height of 200 cm, it must be expected that the Pump delivery rate can be between 700 and 2,000 liters per hour, the value moves at 330 cm even at 4,500 liters.
Tips
It is not uncommon that, especially after very ambitious waterfall projects, the flow velocity in the stream is suddenly too high. One or more big stones help with a reduction and even cause turbulence in the water, which in turn helps with the additional enrichment with oxygen in the pond water.
