Also remove any filamentous algae and check that the pond filter is still giving enough water. Remove dirt at the pump and filter. Only in case of heavy fouling can you decide to rinse the filter materials. Do not do this under the tap, but in a container filled with pond water. Filter materials such as Japanese mats and filter lava are the breeding ground for water purifying bacteria. Maintain the bacterial colony by rinsing carefully and keeping the filter material wet at all times.

GH value up

Dying and decomposing aquatic plants release so much CO2 that acidification of the pond environment is imminent. The GH value must be high enough to bind the excess CO2 in the water. During this period, keep a close eye on the combined hardness and carbonate hardness. Test these values regularly and increase the water hardness with GH Plus and KH Plus. It is important to enter the winter with a GH above 10°DH and a KH above 8°DH. The chances of pond acidification are then minimal.

New pond plans

For pond lovers, the vacation season is ideal for getting new ideas for their own water feature. And once the idea is born, plans can be made for implementation. Fall is the best time to build a new pond or renovate an existing pond. The aquatic biotope then has 4 to 5 months to build up a biological balance. This is important for clear water a good development of plants in the spring. When spring arrives, you can immediately enjoy a beautiful clear water feature.
