In order not to disturb the ecological balance in the pond, it is important to act.
We'll tell you how here.
If you have a pond in your garden and discover algae in it, you don't have to panic.

Algae in the garden pond: how to fight them naturally
First of all, it is important to distinguish whether it is
thread algae
or
floating
algae
.
Thread algae are greenish slimy islands.
They are mainly found on the surface of the water.
As the name suggests, the floating algae float through the pond.
These algae are small and lead to green water once they have multiplied a lot.
The
use of other aquatic plants
helps to keep algae in check or to push them back
.
Because the fewer nutrients there are for the algae, the harder it is for them to multiply.
Duckweed, for example, multiply very quickly and thus offer competition to the algae.
Another variant is to use water lilies.
They deprive the algae of the light they need for rapid growth.
A fountain also interferes with the multiplication of algae - after all, the water is constantly in motion.

good water quality in the pond
, but should always be kept in check. It is best to do this regularly with an algae net. It is worth cleaning the pond every few days from mid-April. In the summer months of June and July you only need to treat the pond every three to four weeks.

This means that the pond should be cleaned regularly.
Because excess fish food or even leaves offer more nutrients than necessary.
In addition, a sturdy oak branch can be placed in the pond.

pH value in the water
.
The only important thing is to remove the branch before it decomposes.
Otherwise, it would reverse the process.
