There are many different variations of pond systems. From small garden ponds with a stream to accessible water areas – there are no limits to the design of ponds. A pond ecosystem ideally regulates itself: pollutants such as animal faeces, falling leaves and other plant and feed residues are broken down by microorganisms such as threadworms, ciliates and other bacteria. Plants and algae also help with this. However, if the ratio of fish stock and pond size is unbalanced, special pond accessories are required to maintain the ecological cycle. Then, for example, fish excretion accelerates the growth of the algae, which reduces the oxygen content of the water and reduces the water quality overall.
In our pond shop, you will find high-performance pond pumps and pond filters that circulate the pond water to stimulate the natural metabolism of the pond. The pump functions as a pond aerator: the water movement supplies the pond with new oxygen and pumps coarse pollutants to the filter. In addition to this mechanical cleaning, microorganisms ensure biological cleaning of the pond system. They settle on the filter material and convert ammonia and nitrite into nitrate, which can be absorbed by aquatic plants.
Smaller garden ponds require at least one internal filter, consisting of a combined pump and filter. The ecosystem of larger bodies of water and streams is adequately supported by complete pond filter systems. The pond pump and filter are used separately. Box filters become necessary when the pond is occupied by kois. They are designed for the large coloured carp and their feeding requirements. If the filter capacity is not sufficient, the pond equipment can be supplemented by a UV water clarifier, in which the microorganisms are then killed. The residues are then removed via the pond filter.
