Relatively simple, they still require a particular interest in the health of the basin and its small ecosystem.

Controlling Your Pond's Nutrient Intake: A Sure Way To Kill Algae Through Starvation

Algae management is in the interests of the health of your fish, not to mention the clarity of your water. Why ? Algae feed on the nutrients available in the water.

We are talking in particular about nitrates and phosphates which, in abundant quantities, contribute to the rapid development of algae. The idea is therefore to think about eliminating these nutrients gradually, in order to stop their proliferation.

To do this, you must not have enough fish in the same basin. It should be remembered that the nutrients, which we were talking about above, are mainly derived from the decomposition of the waste released by the fish. And it is the property of your fish to never be satiated!

The alternative is therefore to continue to feed them, but intelligently. In other words, it will have to be done in small portions of food, several times each day. In the same vein, this is also why we recommend using good quality food.

Doing so will meet their nutritional needs, while keeping the algae issue in mind. The most important thing is not to damage your pond ecosystem because you don't want algae.

Provide enough oxygen to your pond: a better asset to say no to algae

Well-oxygenated water gets rid of algae more easily. Indeed, the latter will not have the possibility of increasing because of the inconvenience caused to them by oxygen. One of the easiest ways to do this is to plant aquatic plants.

There are therefore categories of plants whose presence is a factor in the production of oxygen. In this case, plants like pisties and water lilies have huge benefits in the fight against algae.

However, you should avoid choosing the wrong plants. Finally, your fish themselves also guarantee a significant supply of oxygen.

In the same vein, to have oxygen, you can set up devices allowing a rapid circulation of water. And for good reason, water that circulates well has an adequate concentration of oxygen.

All in all, these different approaches are ways to get plenty of oxygen in your pond.

Deprive your pool of sunshine: a good way to drive away algae

Each plant species has its living conditions. Algae have special living conditions that can be deprived of to promote their death. The presence of the sun greatly facilitates the development of algae.

In its absence, their survival is threatened. This is why you must act on the sunshine in your pool.

But the pool should not be permanently sheltered from the sun. What is needed is to put a large part of your pond out of the sun. To achieve shade, you can decide to install a tree.

Be prepared though, the tree in question may work against you at some point. That is to say, he may ask you for extra work. In particular, you will have the leaves to pick up, and the roots to control. It's normal.

Afterwards, you will have to be content with the shade that it will give you. Some aquatic plants, like those mentioned above, can help you in this regard.

Clear the pool of waste of all kinds: reliable trick to destroy algae

The cleanliness of the basin is of incredible importance in the success of your project. Care must be taken to ensure that all rubbish is cleaned up. As per our previous tip, you should be ready to clear your pond of tree leaves that are cluttering it.

Letting the leaves decompose is contributing to the proliferation of algae. And for good reason, these will become beneficial nutrients for the enemy you are chasing: algae.

Pond cleaning is also about not letting algae grow. In concrete terms, this means that when algae appear, you put yourself in the position of policeman to pull them out of your pool.

The other thing is to arrange the remaining food in the basin. After some time, if you notice a part of nutrients not consumed, it must be got rid of. Algae can take advantage of this.

Apart from plants, snails and tadpoles give you support from the perspective of reducing waste and some algae.

Working the water available in the pool kills the algae

It is obviously necessary to treat the water in the pond to ensure the disparity of the algae. The analysis of the water quality will help you know what measures to take to succeed in the fight.

For this purpose, you will measure the PH of the water or the degree of calcium and magnesium (GH) contained in the pool water. By testing the GH associated with the carbonate rate (KG), you will realize if your water is better or not. The most suitable and recommended water is that which has good hardness.

The GH must then be between 10 and 20°. On the other hand, imagine having drained the algae bed if the water in your pond is immensely rich in nitrates and nitrites. This is indeed the proof that it holds more organic matter than necessary. In this case, you must resort to a treatment for which the expert opinion will be useful to you.

Spreading a filter in your pond makes it easier to do the job

Not only does the filter have the advantage of playing the role of purifier, but also that of prevention. Using them reinforces the maintenance of the pool with the intention of stopping the growth of algae. You will find filters of several varieties that you should adapt to the seasons.
