Why do plants die in the aquarium?


What if plants do not grow?

Why do aquarium plants grow poorly? The most appropriate answer is bad conditions created in the aquarium. Then what needs to be done to make the plants grow better? To solve the problem should use some recommendations.

Causes of slowing the growth of aquarium plants

In an ordinary freshwater aquarium, it so happens that live plants die. Why it happens? In the aquarium should not be a large number of fish. The products of their vital activity in large quantities are harmful to plants. If you decide to add neighbors to the fish, consider whether this is the right decision. It may be better to purchase another tank, and move some of the fish there.

The amount of light also affects the life of water seedlings. Natural light or artificial lighting should be scattered around the area of ​​the aquarium. The length of daylight for most plants is 10-12 hours. Lighting is best done using fluorescent lamps with a power of 0.4-0.5 watts. Set the light intensity yourself, but it is better to start from dim, and ending with a brighter one. But as a result of intensive lighting in water, algae can rapidly multiply, which will also hinder the growth of plants.

Feed the fish should be in small portions, it is better to give 2 times a day as much feed as they eat in 2-5 minutes. It is important not to overfeed, otherwise the remnants of the feed will be oxidized, as a result of toxic ammonia, which also algae. Remove residual food with a siphon with a hose; resort to this procedure as often as possible. Do not forget to clean the water with a filter, do a weekly replacement of water with fresh. Plants in the aquarium prefer pure, infused water.

Why aren't the plants in the aquarium even more magnificent and taller? It is necessary to find out the parameters of the aquatic environment in which the fish and plants live. Water is crucial in the well-being of all living organisms. The composition of water depends on the appearance of vegetation, its growth, reproduction. The less heavy metal salts in water, the better the plants will feel. It is also recommended to make periodic measurements of water for toxic substances, acidity, hardness, oxygen and carbon dioxide levels. Many plant species develop well in a pH-neutral medium, in water of medium hardness. The hardness range is 4-15 dH, and the acidity pH 5.5-6.5 is suitable for many aquarium plants.

See how to make a test of aquarium water for hardness.

In addition to salts, which affect the hardness of water, there are also metal salts (lead, tin, copper, zinc), which can affect the functioning of seedlings. In certain quantities, they are useful, but exceeding the permissible rate is fraught with the death of the seedling. In salts, there are residues of acids (nitrous, nitrate), the concentration of which in water can be several times higher than the permissible threshold. Plants are not easy to process them, so they grow poorly or die.

Saplings can grow poorly due to a close aquarium and poor soil. Tropical species like silted soil saturated with humus. If the roots do not get enough nutrients, they die off. Try using fertilizers to help restore the root structure. A close aquarium also causes poor growth. A stalk will never grow to the desired height if there is not enough room for it.

The water temperature below normal also provokes slow growth. Some plants of temperate latitudes easily tolerate a wide range of temperature conditions (from 14 to 27 ° C). Plants native to tropical latitudes can only live in warm water (22-26 ° C). Lowering the recommended temperature threatens extinction. It is believed that algae are harmful, but Kladofor algae is a very hardy species that withstands moderately cool and warm water. Also hardy are aquarium mosses and ferns.

What needs to be done to improve the growth of aquatic plants?

  1. The lighting should be of such intensity that the light is scattered across the entire surface of the bottom of the tank, reaching a depth of 50 cm. Incandescent lamps are very powerful, so they need to be turned on for a short time, unlike fluorescent lamps.
  2. The hardness of the aquatic environment should not be higher than 15-20o.
  3. Make partial water changes, clean the ground with a funnel hose. Repeat the procedure 1-2 times a week.

    Watch the video about the water change.

  4. In the aquarium should be present plants of different species, preferably as many bushes as possible.
  5. It is not recommended to put in the aquarium fish that harm the green - eat it, dig up the soil with the roots.
  6. In the aquarium it is better to settle the fish that cherish the vegetation - these are labo, moths, guppies, petsia, young antsistrusy, girinoheily, catfish corridors.

  7. Feed the fish moderately, not overfeeding.
  8. If the seedlings are in unsatisfactory condition, take measurements using indicators, soften water if necessary.
  9. Before launching a new tank, plants should be quarantined for 2-3 weeks.
  10. Many species adapt to the aquatic environment gradually, they are passive in their reactions. Observation is required to understand whether the seedling has been able to adapt to new conditions.

Having learned all the possible reasons why plants do not grow lush and taller, you can gradually solve the problem. Make a list of actions, set the correct mode in the aquarium, do everything possible to restore the biological balance of the mini-ecosystem.

Why do not plants grow in aquatic

The aquarium in the apartment allows you to get closer to the wildlife - besides, watching its serene inhabitants is considered an excellent relaxation therapy for the nerves. Often, people acquire beautiful aquariums with exotic fish and suddenly find that the plants simply refuse to grow in them. Why is this happening and how to correct the situation?

Growing aquarium plants

If the plants in the aquarium do not grow, first of all it must be properly illuminated. To do this, turn on luminescent lamps and incandescent lamps so that the lighting can be varied. The length of daylight for plants should be no more than 12 hours, and the intensity of illumination should go on increasing - from smaller light to more. Also, plants from time to time should be vacuumed with a hose with a funnel at the end. It will save the leaves of plants from the precipitation of the soil, which slows their growth - clean soil at the same time will settle down.
The more fish there are in an aquarium, the more often it is desirable to resort to the procedure of cleaning plants from sludge and food residues.
In addition, the growth of plants in an aquarium depends on the composition of the water, in which there must be a certain amount of substances dissolved in it. So, if the minimum amount of salt is present in aquarium water, the plants will grow better. At the same time, the water should not be too soft - rather, moderately hard. Also, plants may not grow due to metal salts present in the aquarium water. They are responsible for the normal functioning of the aquarium flora, so their concentration should not be exceeded.

Aquarium Plant Care Rules

The aquarium should be intensely illuminated (40 watts of luminescent light at 0.3-0.4 square meters of water surface). When installing incandescent bulbs, power should double. The water in the aquarium should be changed several times a week. If the plants refuse to grow in the aquarium or their condition is unsatisfactory, you need to run a small amount of fish in it that cares for the plants - labo, mollies, gyrinoheyls, guppies or petsylii.
Planting an aquarium is preferably thick, using a diverse species composition of plants.
The main types of fish living in an aquarium should not be large in size. In addition, they should not be phytophagous or digging the ground, as this adversely affects the growth and condition of the plants. Feed them should be very moderate, so as not to pollute the water. Before launching fish into an aquarium, plants need to be given several weeks to adapt, and, at the slightest signs of deviation from normal development, soften the water, intensifying this process. Remember that plants have rather inert reactions, so you need to watch them closely.

Why do aquarium plants die?

Much of what explains in varying degrees, the causes of death of plants in amateur aquariums. The main reasons include the chronic lack of lighting and carbon dioxide in the water, the absence of certain components of mineral nutrition. Earlier it was also noted that many plants can be considered water only conditionally, and such as, for example, dracaena, syngonium, chlorophytum, arrowroot, cryptantus and many others, generally do not belong to aquatic plants and can withstand complete immersion for a period of two weeks. up to several months. It is these so-called “false aquatic plants” that invariably die in the aquariums of inexperienced lovers, who purchase them from unscrupulous or incompetent sellers. Nevertheless, even such plants can be used as a temporary decoration of an aquarium, periodically taking them out of the water and placing them in a bright and warm greenhouse for several months so that the plants on the air come to their senses. Strictly speaking, it is impossible to call such an appeal otherwise than mockery of a living being, even a plant.
One of the causes of the death of aquatic plants is the stress associated with their improper transportation outside the water. With such transportation, the leaves, stems and roots of the plants dry up, which then die off. If at the same time a large part of the plant dries up, it is often not able to recover and dies completely, and the painful condition can last for months. For a short period of transportation, carefully enough, without breaking leaves and stems, wrap the plants in a wet newspaper and put them in a plastic bag. Properly packed plants with a root system that develops in a mesh pot filled with mineral wool (see photo) are well tolerated for transportation for several dozen hours in complete darkness and usually start to grow in a few days. It is only important that the plants do not overheat, which in the tropical sun can occur very quickly, and the plants can literally become "boiled." It is also necessary to make sure that the plants do not overcool, since overcooling leads to almost the same effect as overheating. The temperature during transportation of about 20 ° C suits most plants.
The roots of some plants, especially Barclay and a number of cryptocorene, which grow in nature in the so-called anaerobic conditions, that is, in dense, muddy soils, where oxygen is limited, suffer greatly during transplantation and their long exposure to the open air. In this case, they quickly rot away, the plant floats to the surface and often dies. Therefore, the roots of such plants are better, without taking them out (that is, directly under the water, without lifting them to the surface), to wrap together with the adjacent ground a dense plastic bag that does not allow oxygen to pass through. When planting such plants in an aquarium, it is also desirable to avoid contact of the roots with atmospheric air. For this, the plants in packaged form are first immersed in water, and only then the package is unwrapped and the root system is placed in a previously prepared well, and then it is filled up. The amount and quality of the soil must meet the requirements of individual plant species, and will be discussed further. The general structure of the soil in an aquarium and its preparation are described in the book Aquarium — device and care.
The almost complete absence of oxygen in the lower layers of the soil indicates the low redox potential of water RH, which must also be taken into account when moving plants from the aquarium to the aquarium (for example, if you participate in the exhibition) and growing similar species. Increased water circulation, powerful aeration, ozonization, as well as the dissolution in water of hydrogen peroxide or potassium permanganate used to combat algae, fish diseases, etc., lead to an increase in redox

This seaweed has forgotten the truth. The best for an aquarium is called. It filters well, and even the fish eat it, it can grow and not planted in the ground! and rots there because she needs to swim for a while and then when you cut off everything that rots, then plant again, it rots there because there is not enough light at the base of the light.

Why do not grow plants in the aquatic ???


There are two options: either little light, or problems with biogenes. Maybe they overdid it with top dressing? Many aquatic plants can not tolerate their excess. For example, cryptocorynes immediately shed their leaves. Do not "indulge" with air conditioning and aging? For macrophytes this is also not useful! I am not talking about Vallisneria or Elodaea!

It is possible that you have problems with water. Measure stiffness. Plants do not grow in too soft water and too hard. In general, read // You will find a lot of interesting things :) Immediately I will say that I have never bothered with lamps, dressings and CO2. But I constantly hand over plants to the pet store. Grow like yeast! And cryptocorynes, and Anubias, and Echinodorus and a lot of everything else :)


An important factor for plants. For example, Echinodorus osiris, E. portoalegrensis, Cryptocoryne parva grow poorly at great depths. Especially while they are in the process of small shoots. These plants can be found in a shallow pond. Or, for example, S. arnogetifolia passes from the aquatic form of existence into the marsh - a number of large echinodorus, sagittaries and others. Growing deep. With the wrong light home aquarium, it becomes noticeable. You can also notice this if it is unsuccessful to position the aquarium in relation to the source of natural light.
Important are the parameters of water. Water plays a large and important role in the growth and development of fish. For some aquarium plants, not too hard and acidic water is required (especially with a sharp special acidification), fresh water. Consider also the fact that habitual aquarium plants that seem to live beautifully in a common aquarium do not meet in nature. They grow only in certain environmental conditions.
But there are also such situations - it seems that the habitat of the plants is the same, the fish in the neighborhood are the same, the light is also water from the same aqueduct. But in one aquarist the plants look like a blooming garden, while in another they do not multiply, they do not grow well. It is very important experience aquarist. If it is not enough - it is worth looking at big beautiful aquariums, try to copy what you see. As time passes, the skills and ability to deal with plants will appear.
Aquatic plants are also an important element of a complex biological system. Thanks to the plants, the water is saturated with oxygen. Plants consume substances dissolved in water from the decomposition of the products of dying leaves, from the decomposition of fish waste products. Thanks to plants, a number of very important parameters stabilize in water, such as hardness and pH. They can take out excess nutrients from the soil and water. Plants are excellent indicators of conditions in an aquarium — they show whether there is enough light in the aquarium, how long the illumination was (short or long), how much organic matter has accumulated, and so on.
So, how to make the right choice of plants for the aquarium?
In the aquarium should be the conditions that are suitable for the selected plants in all respects. In case of non-compliance with the basic requirements - a small aquarium, strong or weak lighting, too fresh or stale water, old soil - the plants will not go through the acclimatization period and there is a high probability that they will die.
Do not forget to remember the correct name of a particular plant species. In the aquarium should not be nameless or incorrectly designated plants and fish. Often, plants with yellow flowers, the “Echinodorus scaber,” enter the aquariums, although all echinodoruses have white flowers; or "E. argentinensis" with non-existent pigment spots in reality; or "Cryplocoryne thwaiteiii" with leaves without denticles at their edges; or "Nymphaea rubra", in which foliage develops well in the water column, at a time when a typical representative has practically no underwater leaves ...
Based on the experience of aquarists, each can, if desired, ensure that his aquarium has a unique, ever-changing living picture of the underwater world. Creating the necessary conditions for plants and fish, your aquarium will constantly delight you!

Вполне возможно, что у Вас проблемы с водой. Измерьте жесткость. Растения не растут в слишком мягкой воде и слишком жесткой. А вообще почитайте // Найдете много интересного :) Сразу скажу, что я никогда не заморачивалась с лампами, подкормками и СО2. Но растения постоянно сдаю в зоомагазин. Растут как на дрожжах! И криптокорины, и анубиасы, и эхинодорусы и куча всего остального :)

Почему у меня не растут водоросли в аквариуме?

In the aquarium should not be algae, and aquarium plants
Aquarium plants may not grow for several reasons.
1. Lack of light
2. Lack of minerals in aquarium water
(trace elements)
3. Improper soil (size of soil particles)
4. Plants do not live together
5. Plants do not sell chemical indicators of water.
(pH is a pH value and dH is hardness), some plants like hard water, others like soft water.
1. Increase the illumination of the aquarium
2. Under each plant, add in the form of pills in the form of tablets.
(flora 2), or AKVADAR liquid fertilizer (strictly according to the instructions).
3. You can not use very large and very shallow soil (fraction of 3-5 mm.)
4 Try to plant fast-growing durable grasses (Wallisneria, Strelnolist) extremely unpretentious and multiply quickly.

and thank God,
here the plants should grow, can you change the water all at once ??? ?
I need to do a water analysis, I put activated charcoal - it helped.
but 17 liters och few
put at least 60
