Fishpond

A fish pond is a pond intended solely for keeping fish. The complete omission of plants in a fish pond results in more having to be done to keep the water clear and healthy. After all, there are no plants to filter the water and the fish still produce waste material. Therefore, a powerful filtration system is required in a fish pond. Whereas pond plants normally provide the water with fresh oxygen, a fish pond without plants needs an air pump to fulfill this role. Without an air pump, not enough oxygen will get into the pond water and the fish will suffocate. A fish pond without plants will need regular 1/3rd changes with tap water to avoid poisoning or weakening the fish. The KH and GH levels should always be kept at the right level.

Building a fish pond

Fish ponds should be at least 80 cm deep to allow fish to overwinter safely. The water should not be able to freeze over during the winter. An air pump or pond heater can help here. In principle, any fish can be placed in a fish pond. However, pay attention to the size of the fish and pond, the combination of different fish in one pond, and the specific habitat of the fish.

The number of fish that can be kept in the pond depends on a number of factors. Guideline is a maximum of 50 cm of fish length per 1,000 liters of pond water. Too many fish in a pond leads to disruption of the biological balance. The fish then produce more waste products than the bacteria in the pond can process. As a result, the pond suffers from floating algae and becomes cloudy. There is also an increased risk of diseased fish. In a pond that is equipped with a filter system and / or a UVC Filter, up to 25% more fish can be kept than in a pond without such an installation.

Fish pond maintenance

Because the fish pond is dominated by fish, the pond water is soon full of waste products. Therefore, a very strong filter is needed, which, like the pump, should be regularly checked and maintained. The bottom of the pond should also be cleared of silt every year, for this you can use a Bio-Oxydator. Of course, the fish also need attention. They need to be fed and medicated in case of diseases. When a fish gets sick it will have to be taken away from the other fish. Especially when medications are added to the water.
