How to use it correctly

No garden pond without algae growth

Algae are of course not bad in themselves. Algae grow in every garden pond and usually pose no risk, neither for the appearance of the water oasis nor for the biological balance. The most important garden pond algae are:

• Blue and green algae
• Thread algae

Usually unproblematic: blue and green algae

Tiny blue and green algae, for example, are present in every water, even in chlorinated pools. If the population is limited, they do not even cloud the water. In warm conditions and nutrient-rich water, however, they can multiply explosively and deposit as an unsightly slime carpet on the surface of the water.

Thread algae

The pond water can be completely clouded by thread algae when it comes to algae bloom. This is particularly problematic for ponds with fish stocks, because those that die after flowering and sinking algae can cause the animals to suffocate due to the associated deprivation of oxygen bring.

What can be done against algae?

In order to keep algae formation as low as possible from the outset, a constantly low nutrient content must be ensured in the pond water. This deprives the algae of their livelihood. On the one hand, it is advisable to regularly fish off nourishing algae deposits on the water surface and to cut back the marsh plants regularly.

You can take action against algae very effectively, naturally and free of charge by letting the pond planting do the work for you. Species rooted deep in the pond floor draw nutrients from the soil and also from the water, so that less is left for the algae. On the other hand, they give off oxygen, which also keeps the algae away.

Plants against algae

Basically, you should put a lot of plants in your pond so that they absorb the water nutrient content. Heavy eaters are of course best suited.

Easy care

• Horn leaf: The horn leaf, swinging gently like a soft fir branch in the water, has the ability to absorb many nutrients directly from the water.
• Cattail: The cattail is not only an imposing and very classic pond edge inhabitant. It is also a very effective algae inhibitor due to its great hunger for nutrients. In addition, it is easy to care for and not too vigorous.
• Water feather: It reproduces independently on the pond floor and enchants on the surface of the water with its delicate white flowers

Flower beauties

• Water lilies: With their beautiful, large flowers, they are the classic pond romance. They help against algae insofar as they shade the lower layers of water with their flat, ornate floating leaves and make it difficult for the algae to grow.
• Frog bite: With its small, round swimming leaves, it also shades the surface of the water. Its flowers on the water delight in snow-white with a yellow heart
• Swamp iris: With its size and artistic, yolk-yellow flowers, the swamp iris looks very attractive in the garden pond. It is also very effective against algae.
