- Checklist for pond care in summer
Too much heat can have dire consequences for the garden pond. The increased algae growth can lead to tilting of the pond and thus endanger the fish living in it. Optimal pond care in summer can prevent this.
A garden pond is the oasis of peace in a garden. You can really enjoy this only if it looks clean and well-kept. Many give your garden pond an extensive care treatment in the spring. That's right, but that's not all. It is also important that the garden pond is not left to itself in the summer. Because of the hot temperatures and the oversupply of food, whereby the algae growth is greatly increased, it happens quickly that the pond tilts and thus the animals living in it are endangered. In the worst case, these can die.
To make sure that does not happen, it is important to keep an eye on your garden pond in the summer and to take some precautions regularly. Which of these are exactly, you will learn now.
Checklist for pond care in summer
Überprüfen Check water values
The quality of the water determines the life in the garden pond. In order to achieve a balance here, you must regularly check the water values. For this there are special test strips with which the water values can be read very easily. The following values are decisive:
- pH value (pH)
- Carbonate hardness (kH)
- Total hardness (gH)
- Ammonium (NH4)
- Ammonia (NH3)
- Nitrite (NO2)
- Nitrate (NO3)
" PH value
The pH value indicates how acidic (7) the pond water is. If this is too acidic, the fish's mucus and gills will be lost. If the water is basic (alkaline), then ammonium is converted to ammonia, causing the animals to die agonizingly.
So you have to create a balance to protect your plants and animals. The ideal value is between 7 and 8 (tolerance range: between 6.5 and 8.5 pH). Due to rain, fresh pond water and sun, the water is subject to constant fluctuations. Fluctuations of 0.5 pH are permitted, they should not be larger, as this can be harmful to fish and plants.
As just mentioned, the pH is subject to constant fluctuations. Ponds tend to over acidify over time. This is due to the urine of the fish, rainwater or the release of acidic substances of some bacteria. How much the pond can handle these pH fluctuations depends on the level of the carbonate value. To maintain a stable pH, the carbonate hardness must be between 6 and 10° dKH.
The total hardness in the pond water indicates how many dissolved minerals are in it. These are necessary for many biological processes in the water. If the water is too soft (low mineral content) they will not work properly. Soft water is between 8 and 10° dH. You have optimum water hardness when the value is between 10 and 15° dH.
" Tip: The value can be increased by adding fresh water to the pond.
"Ammonia and ammonia
The precipitation and degradation processes of organic materials produce ammonium. Does not matter. It is dangerous if this ammonium is converted to ammonia at too high a pH. Even a small value can be fatal to the fish. The ammonia content in the pond water should therefore be 0 mg per liter.
However, if the meter indicates a value of 0.2 mg per liter, you should urgently carry out a partial replacement of the water. Replace 25 percent of the water at a value up to 1.0 mg per liter. However, with a higher value you should replace up to 75 percent.
"Nitrite and nitrate
Also a cause of fish deaths can be a detectable nitrite value. This ensures that the oxygen transport is blocked and accordingly suffocate the fish.
At a biological equilibrium, however, the toxic nitrite is immediately converted into the harmless nitrate. Plants use this as fertilizer. An excess can increase algae growth. So make sure that the nitrate value is as low as possible - up to 25 mg per liter, everything is fine. In addition, you should use more aquatic plants and make a partial water exchange with nutrient-poor rainwater.
|PH value||6.5 - 8.5 pH|
|carbonate||6° - 10° dKH|
|total hardness||10° - 15° dH|
|ammonia||0 mg / l|
|nitrite||0 mg / l|
|nitrate||to 25 mg / l|
|oxygen||5 - 10 mg / l|
If your measurements show larger deviations than the optimum values stated here, you should definitely take precautions in this regard. This is the only way to maintain the biological balance of the water.
Zurück Cut back water plants
In addition to numerous fish, aquatic plants also belong in every garden pond.They affect the water quality and should therefore not be missed. But what can have a negative effect on the quality is the fact that the plants spread unhindered and grow too abundantly. In the worst case, it can lead to the tipping over of the pond.
You counteract this with a targeted pruning. Just take a pair of scissors and thin out the plants. But then remove any plant remains such as stems and leaves.
»Expert Tip: Only one third of the pond should be planted.
❍ Remove algae regularly
Algae in the garden pond are not uncommon. On the contrary - they should even exist. But only in small dimensions. But as soon as the temperatures rise and the sun shines on the pond, algae growth increases. Especially thread algae are a troublesome problem. So that the algae do not prevail and thus disturb the biological balance, it is necessary to remove them. For this purpose, nets, rakes or even special thread brushes are suitable. Alternatively, of course, a long stick works.
The above-mentioned aids are suitable for a normal infestation of thread algae. However, if this is already too advanced, special algae killers (found on aquagart.de) are the simpler and, above all, timesaving alternative. The remedy is applied directly to the filamentous algae and removes them within 24 hours. It has no negative impact on the fish and plants in your garden pond.
Auf Fill up with water
Especially smaller ponds quickly reach a temperature of over 22° C in summer. When this value is reached, be sure to top up with cold water to prevent oxygen deficiency in the pond.
The same is true in the case of evaporation. In particularly hot summers with low rainfall, many garden ponds lose up to 120 liters per square meter. Again, it is necessary to refill cold water regularly.
❍ Pond pumps and pond filters in continuous operation
Pond pumps and filters should work in summer in continuous operation. Only in this way can it be ensured that sufficient oxygen is permanently available in the garden pond.
The filter pump should be cleaned once a week. That's the only way it can deliver full performance and keep your pond clean.
❍ Special summer food for fish
Fish need valuable nutrients in the warm season. So the feed should be rich in protein in the summer, in order to ensure an optimal growth. In addition, it should be enriched with micronutrients, as the fish can use it better. At the same time, this has the advantage that the precipitations decrease and, in this regard, the nitrate content in the water remains low.
❍ Create a shady spot
As mentioned above, algae grow more often when the garden pond is in the blazing sun. Also, the fish need a shady spot, so as not to get a dangerous sunburn.
The location can not be changed in retrospect, but you can provide shade at the garden pond. For example, an awning can be installed quickly and easily. But a bridge also provides a cool shelter for the fish.
