Artificial reservoirs
Works in spring period

After water in the reservoir has completely thawed; remove all covering (if a reservoir is covered for winter). Then it is necessary to get loading pump, to check it up and to connect, preliminarily having added water in the reservoir up to the usual level. Plants, living in ice at the bottom of the reservoir should be removed and placed on a special shelf. With help of a net the fallen leaves and rotten waste should be taken from the pond. If water is very dirty, it is better to pump it out completely to collect all mud from bottom of reservoir, and fill it with new water.

After the risk of hard frosts passes, plants, which were removed for wintering, may be put back into the pond. Usually it is required to be done once in 3-4 years. At the end of May — beginning of June it is possible to perform sprinkling of plants, and also to treat rhizomes of plants and water with copper sulphate. Special fertilizers for water plants are applied under a layer of gravel in each basket with a plant.

Now different chemicals are available for treatment of reservoirs and water plants, and following instructions for use, they can facilitate essentially many operations on servicing of water containing objects.

Works in summer period

In summer it is necessary to watch constantly for the condition of a reservoir, to disinfect water and to clean it. In hot weather the water level in pond can drop. Therefore it is necessary to add water slowly and cautiously, not allowing the water level to drop by more than 5 cm. It is not necessary to turn off the filtering pump for a not long time, as water may become muddy or blooming.

At this time of year already matured plants do not demand much care, however overgrown coastal plants need to be thinned out. Withered flowers should be removed, not allowing formation of fruits. Otherwise coastal plants become weak, and their seeds soil the pond. Besides, it is necessary to remove on a regular basis dead parts of plants (leaves, stalks) and the other organic waste getting into reservoir (leaves, grass, peat and so forth), not allowing decomposition of organic material.

Periodically it is necessary to check the condition of the filter in the pump and to wash it when clogged.

Works in autumn period

In September or at the end of August when water plants finish vegetation and signs of dying off of the elevated part appear, darkened stalks and leaves should be cut off so that they are a few centimetres higher than water level. It is especially important for plants with hollow stalks. Water lily's withered flowers and leaves should be deleted. Plants floating on the water surface form wintering buds, which then fall on the bottom. Several buds from each plant can be placed in glass with water and put for the winter in a cool place with the temperature of +10°C — +40°C. The next spring they will give sprouts and if one returns them in pond then new plants are formed of them faster, than from those buds that wintered at the bottom of pond. It will facilitate struggle against monocelled seaweed in spring.

If nearby the pond there are deciduous trees the pond needs to be covered with fine grid so that leaves don't get into reservoir, and to fix its edges. The grid is cleaned after the end of fall of the leaf.

In October, before frosts some more actions are carried out. Not cold-resistant plants (water lilies, jugs, mud-flowers, etc.) are removed from reservoir and cleaned in dark room where the temperature in winter will be +10°C — +40°C. It is necessary to put water lilies and other deep-water plants in a reservoir with water and to watch constantly, that water completely covers the plant. Coastal plants need to be put on a pallet and to be watched, that the ground doesn't dry up. The plants remaining for winter in the reservoir, should be put lower to the bottom in the deepest part of the pond. The immersion pump, fountain, illumination and other devices should be disconnected, cleaned and kept tidy in storage.
Atáthe European exhibition ináMadrid copper sulphate ofáour enterprise has been awarded with aáprize for the best quality ináEurope.
Natural, simple and reliable way in repairing warming threads of a rear glass is the electrolyte covering of the not big (not more than 1-1,5 sm) in length areas of these warning threads by copper.
