Vallisneria

maintenance and care, species, reproduction, photo-video review

Wallisneria is one of the most unpretentious aquarium plants. If you have never had an aquarium, you do not have experience in growing aquarium plants, start with Vallisneria.

She does not need any special care. There are no stringent requirements for lighting, water or soil parameters.

Vallisneria goes well with other aquarium plants, grows quickly and looks good on the side and background of the aquarium.

Family: Water colors (Hydrocharitaceae)
Rod:
Vallisneria

Spiral, American Vallisneria, Dwarf Vallisneria, Vallisneria twirled, Vallisneria floating, Vallisneria Twist-leaved mini-twister ”, etc. gracilis, V. gigantea, V. jaquinii, V. mmor, V. nana, V. linnei, V. natans, V. portugalensis, V. neotropicalis, V. spinulosa, V. pusilla, V. tortifolia, V. triptera, V. tortissima, etc.). Representatives of the genus are constantly reviewed, systematized, their names change. This is due to the great similarity of plants.

They are distinguished by the species of valisneria by the length and width of the leaves, their color, shape, type of venation. Depending on the habitat conditions, the plant is able to change its external data ”.

The biological requirements of most representatives of Vallisneria are the same, so their detailing is not critical.

E Vallisneria spiralis Tiger

Growing area: almost all continents in temperate, tropical and subtropical zones. Under natural conditions, vallisneria can be found both in the flowing waters of rivers and standing waters – ponds and lakes.

Unpretentious aquarium plant. Due to the large size it needs an aquarium of solid parameters.

For this reason, giant gallium is not popular among aquarists. It grows with proper lighting evenly throughout the year.

Growing area: Southeast Asia.
Appearance:
large bushes straight stiff leaves up to 1 m in length, different shades of green.
Root system:
Priming:
coarse (pebbles or sand with a grain of 3-4 mm), nutritious. The plant feels good from old aquariums, where there is a large amount of organic matter.

Soil thickness – not less than 8 cm.
Lighting:
bright, 12 hour light day. If the aquarium is low, lateral lighting is desirable, as an addition to the upper one.

Water parameters:

Comfortable temperature: 22-26 ° С, it should not be allowed to fall below 20 ° С. Ph acidity: mild, weakly acidic medium.
Stiffness dH:
less than 8 °.
Regular water changes are not critical.
Accommodation in the aquarium:
can only be grown in a large aquarium.

Reproduction: vegetative, layering.

Vallisneria nana

Growing area: Northern Australia.

This wallisneria has a short rhizome, forms lateral shoots. In an aquarium it reaches sizes up to 30-60 cm, which depends on the power of lighting and the nutritional value of the medium.

The plant has dark green narrow leaves. The leaves in the socket, much narrower than those of other members of the genus Vallisneria, and not very long. It has small teeth on the edge on the top of the sheet.

Wallisneria nana has two forms: either the leaves are hard and up to 15 cm long, or thin, ribbon-like, drooping, surprisingly narrow, smooth, up to 60 cm long.

It is unassuming, like all Wallisnerias, a fast-growing aquarium plant. It is recommended for decorating the middle and background in small aquariums.

It has a longer growth phase and is more light-loving than other Wallisnerias, otherwise unpretentious. Wallisneria nana well develops in alkaline water of medium hardness at a temperature of 25-29 ° С, tolerates deviations from the specified parameters.

It forms many lateral processes and develops well under good conditions. The dwarf Wallisneria has a longer period of adaptation than the other Wallisnerias.

If the plant is well taken, it will continuously give daughters.

Appearance: Vallisneria is a beautiful shrub with narrow ribbon-like leaves from 10 to 80 cm long. Vallisneria foliage is usually strong and elastic; different shades of green and red. Herbivorous inhabitants of the aquarium are not dangerous, except for digging species that can pull out a poorly rooted plant.

Some forms of Vallisneria have very sharp leaves due to small cloves. Therefore, you need to carefully handle it, so as not to cut your fingers.

In nature, sometimes in home pond conditions, subject to the presence of abundant sunlight, valisneria blooms with beautiful small bells that adorn the water surface.

Root system: developed in moderation. Milky yellow roots up to 10 cm in length.

The roots are elastic, not prone to morbidity, easily, compactly assembled and planted in the hole during planting. Deepening – with an open root neck.

Priming: composition and structure are not fundamental. Ideal – gravel fraction from 4 to 6 mm. Soil thickness – 4 cm.

The substrate should be the most permeable, then the plant will take root faster and develop well.

Comfortable temperature: from 18 to 32 ° C. If the water is cooled for a long time to 15 ° C and tends to decrease, the plant may die.

Ph acidity: weak or neutral.

Stiffness dH: average.

Salinity of water: from 0 to 20 ppm.

If you have a frame aquarium or bad tap water, watch the rust concentration in it, the plant does not like it. An excess of copper in water also affects the development of Vallisneria.

This metal can get into the aquarium together with preparations against snails and algae, as well as with medicines for the treatment of fish.

It is better to plant vallisneria along the back and side walls in a group of several plants and quite tightly. It forms a beautiful green wall and is the perfect backdrop for all types of ornamental fish.

To make it easier for you to take care of the aquarium garden in the future, you should purchase Vallisneria from a group of mother and daughter plants.

It is convenient to plant the valisneria next to the filter, in the place of water discharge. Due to the flow of water, the plant will be evenly distributed over the surface. Vallisneria can also be used as a restriction on the spread of free-floating plants by placing its leaves in the form of small islets.

To fix the position of the vallisneria afloat, you can use snags or strong leaves of other plants (for example, Echinodorus).

When the leaves of valisneria reach the surface of the water, they frame it beautifully from above. If there are not many plants, they do not impede the free access of the necessary amount of light to the aquarium.

Otherwise, you should get rid of them. Vallisneria better thin out.

After pruning the foliage looks unnatural, it turns yellow and may rot.

Wallisneria does not require undue attention to itself, does not need special care, but it is impossible to completely ignore the needs of the plant for development. For some time, valisneria can grow in poor soil, with poor lighting and muddy water, but for the time being.

In the end, the plant will begin to languish: almost cease to grow, the leaves will become shorter and fade. Therefore, at least sometimes the grass should be fed with complex fertilizers in the form of tablets or paste. Water should also be changed regularly.

But the peat and clay in the soil is not necessary. Vallisneria also do not need carbon dioxide.

Synonyms: Sometimes this plant is called and written as walisneria, with one beech l. However, it is correct, yet to write with two vallisneria – vallisneria.

Vallisneria americana var. americana

The plant is unpretentious, does not require much attention. American valisneria has many forms that vary in width and length of leaves.

Growing area: Eastern North America.
Forms and appearance: leaves are collected, in the form of rosettes, ribbon-shaped, brittle and soft, sometimes at the edges with the teeth. Representatives of the American Vallisneria subspecies may differ in the structure of the sheet plate and its color (from various shades of green to many shades of red).

Leafy handicaps: leaf width is about 10 mm, with several veins and distinct horizontal strokes.

Broadleaf forms: sheet width up to 25 mm, the vein can be from 5 to 9 pieces. Priming: loose, rich in nutrients, up to 7 cm thick, in tandem with liquid and horse fertilizers, which include iron, is the best option for the full development of the plant.

Lighting: bright, 12-hour light day.

Water parameters:

Comfortable temperature: 20-28 ° C.

Ph acidity: 6.5-8.

Stiffness dH: 5-15 °.

Accommodation in the aquarium: When planting a vallisneria in your aquarium, it should be remembered that the plant grows up to 1 m in height, therefore it can significantly impair the coverage of the underwater world of your pond. If you nevertheless decided to acquire such water weed, then pick up the inhabitants of the aquarium, which is acceptable muffled light.

It is worth noting that Vallisneria americana is most attractive in very large aquariums. A good planting option is about 4 plants per 20 cm2.

American Wallisneria is a background plant, so they are planted along the back and side walls of the aquarium.

The complexity of care: low.

Trimming: you can cut the leaves, but not necessary. After pruning, the plant’s appearance deteriorates and its growth weakens.

Reproduction: vegetative, uniform.

Do you have an aquarium? Then you probably faced such a problem as water blooming: a wonderful underwater kingdom in a flash turned into a jug with stale, greenish-muddy water … In summer, this problem is particularly acute.

But do not be in a hurry to despair, lovers of warm sunny weather – water blooms regardless of the season, and the hot sun rays only accelerate this process. You can even conduct a small experiment: put a jar of water in a place richly lit by the sun.

After two (or even less) weeks, it will be impossible to see anything through the clouded glass, since mother nature will cover the walls and the water in the can with green algae.

So why does the water in the aquarium bloom? The fact is that in the water in the aquarium, in addition to various impurities, there are also various microorganisms that shoulder to shoulder with the fish provide for the circulation of substances in the aquarium and maintain biological balance in this aquatic world. All kinds of microbes and microbody digest the remaining food and excretion of fish, thereby, not allowing rot to the ill-fated remains.

This process was called biological equilibrium. When such “scales” work, the water stays clean and clean for a long time.

It seems to be all right – sit yourself and have fun with these wonderful creatures. But it was not there.

Constant control over this very cycle is necessary, otherwise the water microworld itself will not be able to cope without human intervention: we are responsible for those whom we have tamed. The putrid deposits every day more and more; the processes that help the beneficial environment gradually develop into harmful ones; water becomes acidic.

Simply put, the most favorable conditions for the growth of different algae are created. That is why the water turns yellow in the aquarium.

… And we get an aquarium, all covered with greenery, green water and a lot of problems. The presence of bad bacteria increases dramatically. Rotifers, ciliates and many more different microbes have a green color, so the water seems to be green from the microorganisms there.

All the above written and can be imagined as a blooming water.

I have echinodorus algae turned yellow, what can be caused and what to do.

Tell me why algae can turn yellow in an aquarium?

KulikovaAnastasiya

If the deposits on plants and the ground are brown, then these are most likely diatoms. Diatoms often appear in new, unstable aquariums and with a lack of lighting. Normal lighting – 1W per liter.

Presence of live plants is desirable – they eat up all the organic matter and prevent algae from developing.

In general, in order for nothing to turn yellow, not turn brown, not turn green and not rotten, you should try to create a biological balance in the aquarium. )) Good soil, lighting, live plants, biofiltration, weekly water changes of at least 25%, siphon, a minimum of fish. On the Internet, a huge amount of information on the proper launch of the aquarium)) Learn.

Why, in the aquarium bought purchased algae badly and what to do, so that they take root better.

Imfredil

each plant needs certain conditions before buying a particular plant is better to ask or read about the conditions of detention and then there will be no problems
The causes of plant diseases can be related to the characteristics of the soil, lighting, water, lack of chemical elements, or the inhabitants of the aquarium can be the cause.
As a result of stress, the plant, when exposed to uncomfortable conditions, begins to degrade and dies. The diseased plant is easy to recognize, its color changes, it turns yellow and languishes.

As soon as you notice that the algae disappears in the aquarium, as soon as possible remove the damaged parts of the plant. Remember that avoiding plant diseases will help you regular water changes, cleaning the aquarium and comfortable conditions of detention.

Algae – this is undesirable lower vegetation in the aquarium, and you, apparently, do not take root aquarium plants. Light and nutrients are very important to them. The stores sell special supplements for aquarium plants and in the form of a liquid, and in the form of a tablet.

You divide it into pieces and dig into the ground under each root. Oh, and lamps, of course.

They can eat fish.
