A waterfall in your pond
If you want a waterfall in your pond, you may choose from a natural waterfall. Natural waterfalls flows downwards, for example through natural stone or rock boulders. A straight waterfall from stainless steel is an other option. Waterfalls usually flows into a pond, however that is not a must. It is also possible to create running water in the garden, without pond being there in the neighbourhood. Waterfalls can also flow for example into a digged in container or into a pit equipped with pond liner. The pit has to be filled with boulders and or gravel, in which the water is draining away and will subsequently bubble up again in a different place. Then you need a pump. Which you place in the catcher container. From there it will pump up the water again.
A waterfall is useful
Waterfalls are not only for your own pleasure, but it also has added value for the pond. Owing to the water circulation the oxygen content in the water will rise, which benefits life in the pond.
If a stream is involved, between the rock bacterial growth is taking place, which helps waste material in the water to be converted into nutrients which are useful for plants. If you pass on to provide (part of the) the stream with strongly nitrate absorbing marsh plants, you will be disposing of a strongly biological and beautiful natural filter.
