Canadian waterweed (American Waterweed, Pondweed) is one of the most common aquatic plants on Earth. Homeland - North America, where it grows in abundance in stagnant and slowly flowing waters, in ponds, deep ditches, river creeks, oxbows, canals. On the territory of the European part of Russia, elodea is widespread. Due to its ability to grow very quickly and densely fill water bodies, it is called "water plague". A very unpretentious plant. It grows, floating freely in the water column, throughout the year.

Elodeya produces long, highly branched stems that grow extremely quickly and often reach lengths of more than two meters. The stem, floating at first, takes root easily, producing long, up to 40 cm rhizoids. The roots are missing. These stems are very long, thin, fragile and covered with oblong-linear leaves, which are arranged in rather dense whorls, three leaves in each. Leaves are bright green, transparent, from oblong-ovate to linear-lanceolate, slightly curly, sharp, finely serrate along the keel. In the crown parts of the stem, the leaves are always lighter in color than in the lower ones. The flowers are twofold: female and male, and are located on separate individuals. Bright green, with a metallic sheen, Elodea twigs cover the bottom and, rising to the very surface of a shallow reservoir or aquarium, form a dense emerald network in the water,which makes elodea one of the adornments of the underwater landscape.The Canadian Elodea grows very quickly and, under favorable conditions, can fill the entire aquarium.

Elodea is best suited for cold water to moderately warm aquariums. It grows satisfactorily at a temperature of 16-24 ° C and tolerates a prolonged temperature drop to 12 ° C. It cannot grow for a long time in a tropical aquarium. The hardness and active reaction of water do not matter for elodea, it grows in both very soft and hard water. He is very afraid of the admixture of sodium chloride and iron oxide in the water and quickly dies in such water.

When moving a plant from one body of water to another, it is necessary to take into account the characteristics of the water. When a plant is transferred from very soft water to hard water, it quickly dies, its branches literally dissolve. Moving to softer water for Canadian Elodea is painless.

В аквариуме с мутной водой элодея становится прекрасным фильтром, собирая на себе частички мути, так что вода делается кристально чистой. Благодаря очень быстрому росту, она усваивает многие вещества, накапливающиеся в воде аквариума, что также способствует ее очистке. Заросли элодеи очень хорошо подходят для нерестовиков с живородящими рыбами, так как в них находят убежище мальки и подросшая молодь.

It is easy to accept elodea in an aquarium: you need to plant its branch without a root in the ground or even sand and watch that its end reaches the surface. In order for it to be bright green, it is necessary, in addition, to plant it as short as possible, or, even better, without planting it in the ground, leave the branches floating directly - until they take root themselves will not take root, for which it is necessary to pour as little water into the aquarium as possible: the shallower the water, the sooner the roots will reach the ground.

The lighting for elodea should be bright enough, but it can withstand moderate dimming. Direct natural light is very beneficial for her. For artificial lighting, fluorescent lamps of the LB type and incandescent lamps are suitable. The power of the illuminators is selected individually, depending on how the aquarium is located and what plants surround the elodea. Elodeya is very afraid of the admixture of sodium chloride and iron oxide in the water and quickly dies in such water.

In the autumn-winter period, with a lack of lighting and low temperatures, the Canadian Elodea sinks to the ground, preserving the growth buds. When conditions improve, it begins to grow rapidly again. While maintaining a satisfactory water temperature and sufficient lighting, elodea decorates the aquarium all year round. Elodea reproduces very easily by cutting the stem. In order for the plant to adapt well and quickly to a new place, the length of the cuttings must be at least 20 cm.

It is necessary to be very careful to remove overgrown elodea from the aquarium, since the plant sap is poisonous and, getting into the water, can cause the death of fish fry that settle in the thickets.
