How to clean a pond? 3 steps
Maintaining constant water parameters guaranty pond biological balance. We advise which care treatments are required by the backyard water reservoir and when to clean the pond.
STEP 1 – REMOVAL OF ORGANIC RESIDUES
Fallen leaves should be regularly fished out of the pond and rotting plant parts should be removed. A bucket with a long, strong handle will be useful for this. One of the effective ways to maintain order in the pond in winter is to put a net over it – only then will we be sure that the bottom will not be contaminated with an excess of fallen leaves that we have not managed to catch.
Filters are used to maintain proper pond water quality – especially in smaller ponds. The main benefits of pond filtration are: regulation the hardness and pH of the water and trapping suspended matter. A surface water purifier, i.e. a skimmer, can be very helpful in catching larger organic residues. It is connected to a filter – the contaminants are then sucked and collected in a container, and the pond owner needs only to clean the sieve. Remember that filters function only in spring and summer – they can’t be left in the water for the winter.
STEP 2 – COMBATING ALGAE
Algae invasion usually occurs in spring, when other plants are still dormant. Thread algae, which look like a green-brown scum, must be caught quickly, otherwise they will decompose becoming toxic for any live.
Remember that strong sunlight helps algae develop, so it is worth planting trees and shrubs around the pond. Too high water hardness works in a similar way – the calcium content in the water can be lowered by sinking bags with acid peat in the pond or by using peat filter media. For the same reason, water shortages that occur in hot weather are recommended to be refilled with rainwater instead of tap water.
STEP 3 – REMOVAL OF EXCESS SILT
The silt consists of zoo and phytoplankton debris, dead plant parts and fish excrement. If too much of it is produced, the process of shallowing of the reservoir takes place. It begins on the shoreline where the emerged plants grow, because this is where the fish do not dig the bottom. As a consequence, a thick layer of slurry is formed, which is devoid of fertilizing value, but emits poisonous marsh gas containing methane and hydrogen sulphide. Basic pond mistakes can lead to dangerous and hardly to fight consequences.
To prevent them, we advise to limit the amount of silt by draining the breeding pond in the winter. In case of backyard pond, such a procedure is carried out in spring or autumn every 3-5 years. Fish should be caught and placed for some time, eg in a bathtub. It is recommended that one third of the volume of water be pumped out and stored for reuse.
Tip: Don’t use any sharp tools when working at the bottom of the tank. You will avoid damaging the insulation this way. The tank should be refilled with tap water mixed with rainwater.
