Microorganisms | The importance of bacteria in the pond
Microorganisms, also called microbes, are organisms that are too small to be seen with the naked eye. This includes a wide range of organisms, such as bacteria, viruses, algae and fungi. Read all about the importance of bacteria in the pond, regardless of the type of pond you have.

Bacteria, what are they?
Bacteria are microorganisms found in large numbers in nature and can be both beneficial and harmful to humans. They are important for various biological processes, such as breaking down organic matter in soil and aiding in our digestion.
Why are bacteria important for the pond?
Adding pond bacteria is important for the pond because these bacteria play an important role in the pond ecosystem. They help break down organic material such as leaves, plant debris and fish waste, making the nutrients available to other organisms in the pond. In addition, good pond bacteria can help prevent algae growth and maintain healthy water quality, which in turn provides a healthy environment for plants, fish and other pond animals in the pond. Also pond plants should not be missing from the pond, as aquatic plants help keep the pond clear and clean. Choose plants with different functions so your pond stays healthy. Oxygen plants provide pond water with oxygen so fish stay healthy and aquatic plants can continue to grow. Also marsh plants With their colorful flowers they also attract insects and other animal life to the pond, which enhances biodiversity. biodiversity in the garden.
Pond plants as natural pond filterers
If you are interested in a natural pond in the garden, it is important to choose sufficient and different types of aquatic plants. After all, they all have their own special and important function. - Simon

Which fungi are useful?
Fungi are a specific group of microorganisms that feed on organic matter and reproduce through spores. Although some fungi can be harmful and cause infections in humans and animals, fungi can also be useful to humans, such as in making foods like cheese and bread. In nature, fungi play an essential role by providing the necessary breakdown of dead organic material. For example, they process dead leaves or fallen tree trunks and are thus nature's clean-up agents. They are used in crop protection and are ideal objects of study for genetic studies.
What are algae?
Algae, also called algae, are a collection of several groups of simple organisms that extract energy from sunlight through photosynthesis, producing oxygen, similar to plants. However, unlike aquatic plants, algae do not have complex structures such as roots, stems and leaves. Although some types of algae have benefits, such as producing oxygen and serving as a food source for pond fish and other organisms, excessive growth of algae can lead to undesirable effects, such as reducing available oxygen in the water and creating toxic blooms (large amounts of algae, which form a thick floating layer on the surface of the water and cause a lack of oxygen in the water). In the pond, it is important for algae control care, to maintain clear water and healthy plant growth. Water lilies help prevent algae formation and offer aquatic animals protection from danger due to their large leaves.

The difference between thread algae and floating algae
Thread algae and floating algae are types of algae found in all kinds of ponds and ditches. The main difference between filamentous and floating algae is their physical structure and growth pattern. Thread algae have long, thread-like structures that float on the surface of the water or grow on the bottom of the pond, while floating algae float in the water as individual cells or small groups of cells and create a cloudy, green color in the water. Both types have undesirable effects on water quality and pond life.
Frequently asked questions about microorganisms
In general, microorganisms need three essential elements to multiply, namely moisture, food and suitable temperature. When these three conditions are present, microorganisms can thrive and flourish.
Besides the aesthetic aspect, algae can be harmful to the plants and even fish in your pond or aquarium. The presence of algae can be caused by several factors, but often occurs when there is an imbalance in the ecosystem of the aquarium or pond.

Pond specialist and aquatic plant grower since 1986
Simon's vision is to let nature do its work in your pond. No need to buy all kinds of measuring equipment and water improvers. If the fish are swimming nicely and the plants are growing well, then the water in the pond is of good quality. With a good planting plan and the right approach, you can save a lot of money and maintenance, and ensure a clear, biologically balanced pond that becomes more beautiful every year.
