It should be the highlight in your garden, but then it becomes cloudy and green - the stream. Find out here what you can do against algae in streams, what causes it and how you can efficiently prevent algae.
What can I do against algae in the stream?
First you shouldfish the algae with a net. Temporarily dry the stream and wash the stones well. A high-pressure cleaner is also suitable for this. Then add enough clear fresh water to the stream circuit.
Why do algae form in streams?
In a stream, the shallow water depth meanswarmer temperaturesThese promote algae growth. Black pond liner also warms the water. Algae need many essential nutrients, such as phosphate and nitrate, which they get from the water. Therefore,nutrient-rich waters are infested with algae. This is the case, for example, if you integrate pond water into the water cycle of the stream. A good water filter system in the garden pond is therefore essential to avoid algae formation.
How can I prevent algae in the stream?
Make sure there is a constantflow of fresh water and the draining of used water into the collecting basin or pond. When designing, use cleaned gravel to avoid spreading dirt or plant matter. If you use a pond at the end of the stream, it should be kept clean regularly and natural algae growth should be reduced to a minimum. Use aquatic and marsh plants in the stream. These filter the water naturally. Use a suitable pump with an integrated filter.
What remedies can you use against algae in streams?
The first step in combating algae should be mechanical fishing using a landing net. This frees the stream from the largest amount of algae. However, you can also lower thepH of the water to prevent algae from spreading. For example, you can hang a jute bag with untreated peat, oak bark or oak leaves in the collection container or pond.
How does the location affect the formation of algae in the stream?
Basically, you should find a partially shaded or shady place for your stream so that as little water as possible evaporates. In addition,strong sunlight promotes the formation of algae. However, a place under trees is also unsuitable. Here a particularly large amount of leaves, needles and small branches fall into the stream and contribute to greater contamination. A leaf protection net can provide some relief here.
Tip
Easily build a fine network of algae yourself
The thread algae is easy to fish. Floating algae, on the other hand, are much finer and difficult to catch with a standard landing net. Just use an old pair of tights. Using a thick wire, bend a large loop and stem. Cut the tights to size and place them over the wire frame. This means you can fish out even small components effectively, quickly and thoroughly.
