An aquarium with natural greenery looks very beautiful, resembling a piece of wildlife in your home. In addition to the natural appearance, the plants are very useful, because they absorb the waste products of fish, can serve as a top dressing and do not emit harmful chemicals into the water.
The transition from artificial to real plants can frighten beginner aquascapers, so it is best to start with light, fast-growing species such as valisneria.
Wallisnerias in aquariums are very popular due to unpretentiousness and rapid growth. For a couple of months, a small bundle of a plant grows to a chic shrub, it is time to weed it, plant bunches in suitable places or share vegetation with friends.
Helix Vallisneria is one of the most interesting types of Vallisneria. Its distinctive feature is elegant, twisted spiral leaves.
For a short period of time, it forms dense thickets that can be used by the fish as shelter.
Helix Vallisneria has narrow, ribbon-like leaves twisted with a corkscrew. Depending on the lighting, it may acquire a different color: from bright green to reddish.
The length of the leaves ranges from 10 to 80 cm, depending on the conditions of detention and variety. With good consecration, it can begin to bloom, releasing inflorescences resembling white bells on the water surface.
A developed, elastic root system with white roots is not prone to injury, the plant is planted in a hole in the ground and straightens the roots.
Spiral Wallisneria looks best on the back or side walls of an aquarium. In order to thickets were denser, it is recommended to plant several beams next to each other, in this case the plant forms a dense wall, which will serve as an excellent background for fish.
Spiral vallisneria can also be combined with other vallisnerias. For example, land a gigantic background, and a spiral one on the middle or at the sides.

- powerful lighting;
- regular water changes;
- top dressing is not required;

- river sand or small pebbles with a fraction of 6-8 mm is used as a soil;
- soil thickness 4 cm
In general, the plant is unpretentious, you only need to make substitutions 30% once a week to remove excess organics and reduce the concentration of waste products of the inhabitants of the aquarium. With a high concentration of nitrites and nitrates, the leaves are depleted and small holes appear in them.
In case of insufficient light, the leaves may turn yellow and stretch, spoiling the appearance of the aquarium. All spectra, natural light and fluorescent lamps are suitable for Vallisneria.
Plant reproduction in comfortable conditions is not difficult. With bright light and temperatures above 20 ⁰C, it accelerates its growth and gives new shoots.
It is possible to separate a daughter bunch after on it there are roots and several leaves.
In nature, vallisneria is heterogeneous and propagated by seeds. During flowering forms inflorescences on the surface of the water, resembling white tulips.
Pollen spreads over the water surface and fertilizes them, after which seeds are formed.
Vallisneria and its shoots
Like other aquarium plants, valisneria is prone to disease. As a rule, diseases provoke inadequate environmental conditions, lack or excess of any elements.
- If the leaves of the plant turned yellow and began to die, then this indicates a lack of iron. To replenish it, you need to add 0.1 mg / l of iron sulphate once a week. When the element is abundant, the leaves turn yellow, but the veins remain green. In this case, you need to use manganese in small quantities.
- If the tips began to turn yellow, then you need to deal with a lack of calcium. It’s enough to put a few large shells on the bottom.
- With a lack of nitrogen, the edges of the plant begin to turn yellow. In order to solve the problem, it is necessary to lower the temperature in the aquarium for several days; this will increase the concentration of nitrogen in the water.
- Lack of phosphorus causes redness of the leaves, young shoots begin to darken and curl. In order to increase the concentration of phosphorus, it is necessary to add phosphate fertilizer to the water.
- When yellowish spots appear on the surface of the leaves of vallisneria, nitrophores need to be applied at a rate of 2 g / 100 l every week to replenish potassium.
- If the tops of the plant turned black, then boron deficiency needs to be addressed. For this you need to make boric acid 0.2 mg / l.
- The loss of color and the death of the leaves may indicate a lack of copper. To compensate for its deficiency, you need to make in the aquarium copper sulfate at a concentration of 0.2 mg / l. After the restoration of the plant, the introduction stops, as an excess of copper has a detrimental effect on the vegetation and other inhabitants of the aquarium.
With the help of spiral vallisneria you can create elegant compositions in an aquarium. Due to its spectacular appearance, this plant can provide decent competition for artificial decorations.
