The bad news first: With a professional pond care alone can be in most cases not prevent the garden pond remains algae-free in the long term - the prerequisites are namely already created when the garden pond. Make sure that the planned pond is at least partially shaded so that it does not overheat in summer. In addition, do not plan the water too small and too shallow - the larger the amount of water, the more stable the ecological balance. Rule of thumb: The garden pond should be at least 10 to 15 square meters and at least 80, better 100 centimeters deep. A water volume of 5,000 liters is considered a good size.
Place the garden pond in such a way that the rain does not wash in garden soil. You can prevent this, for example, by sticking the edges of the pond liner a few inches out of the ground. If you hide them with stones, they still remain invisible. Moreover, do not lay your pond at the lowest point in the garden, even if that looks best in terms of design. Use only nutrient-poor ponds for the plants and as little as possible. This is possible by placing all plants in plant baskets or plant bags. The shallow water zone with marsh plants should not be planned too small, because it acts as a natural wastewater treatment plant for the pond.
All subsequent pond care measures should be designed to continuously extract nutrients from the garden pond while at the same time preventing too much nutrients from entering the garden pond.
Stretch the leaf protection net over the pond
The annual fall of leaves in autumn has already caused many a pond to tip over. The autumn leaves are blown onto the water surface, slowly sinking to the ground and transformed into sludge, which continuously releases nutrients and harmful digester gases to the pond water
A leaf net prevents leaves from being blown into the pond in autumn
Prevent the foliage entry with a so-called leaf protection net. At the beginning of September, cover the entire water surface of your garden pond with it. Ideally you stretch the net like a pitched roof over the pond - to do so, set up in the middle of the pond from one bank to the other a simple wooden frame made of planed roof battens with a horizontal "ridge" and put the net over it. So the leaves do not stay in the middle of the pond on the net, but slip off to both opposite banks and you can easily collect the leaves there.
Cut back plants regularly
One of the most important measures in pond maintenance is the regular pruning of the plants in and around the pond. The green pond inhabitants continuously extract water, nitrogen, phosphate and other nutrients from the water, which potentially also promote algae growth. For example, cut all yellow leaves from the water lilies in autumn and remove them from the water before they sink to the bottom. You should cut the reeds and the remaining plantings of the marshes and shallow water in the autumn or spring just above the water surface. Do not put the clippings on the compost immediately, but store them in a sheltered spot in the garden until spring. Specifically, the hollow stems of reed and Rohrglanzgras be used by various insects as winter quarters.

Underwater plants such as the water plague and the millet are simply thinned out as needed throughout the season if they have spread too much. A reduction of the near-surface plant mass before the first frosts makes sense, because these often die off in winter anyway and then leads to unnecessary accumulation of dead organic matter at the bottom of the pond.
Despite careful pond care, sludge formation on the river bottom can hardly be prevented. Among other things, the sludge is produced from fine inputs such as dust, pollen and plant seeds and is not problematic in smaller quantities. However, if the layer becomes so powerful that the digester gases blow to the surface from time to time, there is an urgent need for action: with a special pond sludge sucker, you can remove the nutrient-rich layer from the bottom of the water without draining the water. The electrical equipment basically works like a vacuum cleaner: the sludge is sucked off the ground with a pipe together with the pond water and settles in a bag in the collecting tank. The water is filtered through the bag and returns to the pond through a hose at the bottom of the sump.
Since you usually rarely need pond siphon, you can borrow the equipment in some garden or pond shops also. The nutrient-rich mud can be added to the compost in thin layers or used as organic fertilizer for your hedges or fruit trees.
Fish thread algae
When the water warms up in the summer, a few filamentous algae often form even with intact water biology. These should be scanned and composted in a timely manner. There are special nets and so-called algae brushes in the trade, with which this pond care measure is done quickly.

Clean filter systems regularly
To maintain the pond, it is also important to keep the filter system clean. It is especially important if you want to keep fish in your garden pond. Their feces sink to the bottom of the water and release the nutrients contained in the decomposition to the pond water. The amount of fish depends on how much you feed, because especially goldfish multiply very strongly with regular feeding. Therefore, it is usually better to put only a few fish in the pond and to refrain from feeding completely. A garden pond with well-grown plants usually provides enough food for a few goldfish.
Some filter models have a special display that shows when they need to be cleaned. The filter chamber usually contains several inserts with filter sponges that gradually free the pond water from coarse dirt particles and also bind the nutrients and toxins contained. A very important part of the filter system are the bacteria that live in the filter sponges. Therefore, it is important that you do not rinse the sponges with clear water, but only wring out by hand. The suspended solids that collect at the bottom of the filter chamber can be drained via a valve, depending on the model.
