Part of the pond maintenance is that you regularly clean it. That is the only way it can remain attractive and provide a healthy habitat for plants, fish, and other animals. To make this possible, you should dislodge and filter useless organic material.
Why algae become a problem
Algae are a problem for almost every pond, especially in summer. When the temperatures rise, and there is a lot of sunlight, they multiply unrestrained. As a result, the oxygen concentration in the water decreases sharply when the algae die off, causing fish and pond plants to suffocate.
Cleaning the garden pond: Drain the water too
If the entire pond is covered by a carpet of algae, the only thing you can do is to pump the water out first so that you can clean the garden pond thoroughly. You have to remove all the water – preferably with a powerful pump – and then resettle the plants. Only then you can start cleaning the pond walls with a scrubber and steam jet.
Make sure that the foil of the pond has cracks through which water can escape. You can then let freshwater flow into the pool and put the plants back where they used to be.
Tip: If you keep fish in the garden pond, just leave some of the water in the pond. The fish can stay in this puddle during cleaning. If a little old water remains in the pond, this has the additional advantage that the original composition of the pond water regenerates faster. That method is much more pleasant for the fish.
Regular pond maintenance and mud removal
Water plants should be placed in the water so that you don’t have to clean the garden pond so often. They bind nutrients and thus deprive the algae off their basis from the very beginning. You should also regularly fish for algae with a landing net.
Especially in autumn, you can also use a net over the pond to prevent too much foliage from falling into the water, which can cause an unhealthy climate in the pond during the rotting season.
If you want to remove sludge from the pond and remove small amounts of sediments, you can use a pond sludge vacuum cleaner. Afterwards, you do not necessarily have to dispose of the sludge: you can use it very well as fertilizer for your garden beds. You see, pond maintenance can also benefit the rest of the garden.
