Elodea Canadian (Elodea canadensis) or, as it is called, “Water plague” – aquarium plant of the Vodokrasovye family (Hydrocharitaceae).
Elodea Canadian is one of the most common aquatic plants in the world. The name indicates the birthplace of this plant – North America, from which more than a hundred years ago was brought Canadian Elodea to Europe.
In Russia, the plant grows in reservoirs with stagnant and slow-flowing water in the European part of the country and in western Siberia. Second name “Water plague” or “Water infection” because of its peculiarity, the plant has grown to grow rapidly and create dense accumulations that hinder fishing and navigation.
Stems Canadian Elodeans cord-shaped, long, reaching three-meter length, form dense matted thickets. Castings have an elongated shape, are 1 cm in size and half a centimeter wide, painted in bright green color.
Grows elodea canadian swimming in the water column.
AT content Canadian Elodea very unpretentious plant. Feels comfortable in aquarium with cold or moderately warm water.
In tropical aquarium quickly dies. Water temperature recommended for plant content, is 16-24 ° C.
Long-term decreases in water temperature to 12 ° C do not affect the plant in any way. Active reaction and water hardness do not matter elodea develops well in both hard and soft water.
But when moving plants from one aquarium in the other, it is necessary to pay attention to the parameters of water, since the plant will transfer the plant to softer water without loss, but the transfer from the soft to the hard water will kill the plant, its stems dissolve before our eyes. Elodea Canadian is a powerful natural by filter, collecting on its leaves the particles suspended in the water of turbidity and thus making the water in aquarium crystal clear. In addition, the plant absorbs nutrients in the water in large quantities, highlighting the substance with bactericidal properties, which helps to combat the appearance of blue-green algae (which are actually bacteria).
Aquarium lighting, which contains elodea, It should be bright, but the plant tolerates moderate shading quite well. As sources of artificial lighting aquarium It is possible to use both incandescent and luminescent lamps.
The power of the lighting devices is selected taking into account the location aquarium and the needs of plants adjacent to elodea. For development aquarium plants natural light is very useful.
In a natural habitat in the winter Canadian Elodea, maintaining growth buds, sinks to the bottom. With the improvement of light, the rapid growth of the plant continues.
In the face of aquarium, while maintaining favorable conditions, the plant grows evenly well throughout the year.
Breeds Canadian Elodea easily, with the help of cuttings, the length of which should be at least 20 cm. In this case, the plant adapts quickly and well to the new place of residence. The sap of the plant is poisonous, therefore, in order to avoid the death of those hiding in the thickets Elodea fry aquarium fish grafting is best done in a separate container.
Besides the sap of a plant caught in water aquarium, affects the growth of many other plants, slowing it down.
