Threads in the aquarium: the causes of the appearance of algae and methods of struggle

The thread is aquarium algae, which is famous for a huge burden for life. She seeks to conquer all the available aquarium space, and very soon through thick threads it becomes impossible to see the aquarium inhabitants. Some fish love to be touched by a nitacity, but still this plant brings much more harm than good. It is important to get rid of it on time, and it is not so easy to do it.


First, the aquarist notices unusual threads that grow out of the soil and stretch up. At the roots you can see the untidy fluff, layerly covering ground. After a short time, these threads grow so that all the rest of the vegetation turns out to be in captivity of this phenomenon and is covered with an unpleasant mold. This is a thread.

Under this name, there is a few varieties of algae, differences between which can only be seen under the microscope.

Nevertheless, it is very important to determine the type of plant, as it will determine the reason for its appearance and avoid mistakes in the future.

Several varieties isolated.


The most frequent unwanted guest in home aquariums. At first it resembles a light form on vegetation, and later the green threads stretch out of it. Usually the reason for the appearance of this species is the deficit of nutrients in water and substrate.


Looks like an unattractive green mucus, the scale of which increases every day.


Usually arises in new aquariums, where the microclimate has not yet been formed. This species feels comfortable at elevated ammonium rates and low levels of nitrites. As soon as the biological balance will resist, the plant will disappear.

On the touch these algae slugs, unpleasant, when extracting from the water, they hang. In the aquarium, this plant is dangerous in what leads to the death of other vegetation. The threads are tired of the stems and the leaves of the green neighbors to which the light ceases to flow, respectively, the development stops and the plant dies.

Another problem occurs when fetching.

In this case, in the water from its rotational particles there are many toxic substances, the number of which only increases and over time becomes detachious for aquarium fish.

Cases are known when small fish or fir tangled in dense nital thickets and died. In addition, the thread significantly changes the aesthetic appearance of the aquarium, under its influence, the water seems muddy, neglected, the competence of the aquarist is in doubt. The only advantage of this plant can be considered the fact that his appearance speaks of favorable conditions for the development of plants in the aquarium.

Causes of appearance

Before proceeding to the methods of combating such a misfortune, as a thread, it is important to find out the reason for its appearance. The following factors may affect its occurrence:

  • Powerful lighting – this aquarium offender loves natural or artificial light, and the more more, the filamentous algae + often the phenomenon is observed in the aquariums, where the light turns on more than 8 hours a day+
  • Oxygen deficiency is possible when refusing to use aeration system+
  • Small vegetation in the aquarium – if other plants planted a little, then the thread begins to enriched with the useful components contained in the soil, which would have to be aimed at the development of other aquarium cultures+
  • Rare water change – in dirty water contains a high percentage of nitrates that are necessary for the growth of the thread+
  • Transfer with other plants – the thread can “move” to the home aquarium, hacking behind the stems of another plant, which bought for landing into an artificial reservoir.

How to fight?

To get rid of nichtal algae, first of all, it is important to establish high-quality filter operation and reduce the intensity of lighting. Replace blue light more weakened. With a clogged filter in the water accumulate ammonia, which is favorable for the development of the fiber, so start cleaning the filter more often than read before. Plant more plants in the aquarium, floating and those who are developing rapidly. New algae will take place to absorb nutrients, taking them to the thread, which, in turn, will slow down growth rates.

Follow the iron level in water. Its allowable concentration is 0.2 mg / l. If the alcohir was settled in the aquarium, remove it manually.

Sometimes it becomes the only effective measure of the fight against filamentary thickets. Seeing characteristic threads on plants, rinse algae and remove the first signs of the thread. So that this unpleasant vegetation is quickly extinct, on three days during the period of cleansing events, dial the aquarium.

Another method of struggle is the use of hydrogen peroxide, which does not like the prick. Aquariums use a means in proportions of 6-10 mg per liter of water.

It is possible to fight this phenomenon and naturally, for example, tightening the inhabitants who love to be touched with green threads.

These include carposyl fish, Pecilia, Jordell, catches, gastromisons. Turn on the oxygen supply only during the daytime, and turn off the compressor overnight.

Prevention measures

It is always easier to prevent the appearance of a fiber than to overcome her thick thickets. To prevent this detrimental phenomenon, use the recommendations of experienced aquaries.

  • Before you run a new plant into the aquarium, carefully inspect it for the presence of an extraneous gun or threads, thoroughly rinse it, cleaning from all suspicious particles. This measure will avoid the transfer of the wound on the plant.
  • Follow the purity of water in the aquarium, make a weekly 1/3 of the volume of water, pour fresh water outstanding during the day. Dirty water contains decomposition products and nitrates that have a beneficial effect on the development of the prick.
  • Do not put an aquarium for a sunny place. The most unsuccessful plot for him – window. Control the artificial lighting, turn on the lighting devices for no more than 12 hours a day – this time is enough for the comfortable existence of fish and plants, but the thread when the lighting time decreases its uncontrolled growth.
  • Rail to the aquarium as many plants as possible. The path they absorb all nutrient elements from the soil, not yielding the place to the nitchatt, and suppress its development. For this purpose, the most simple inexpensive cultures will be suitable, but most often aquarists advise the use of a rogolistnik. If the plants are planted into aquarium with cichlids, it does not always lead to a successful result, since these fish love to dig in the ground, and vegetation does not take root. In this case, choose plants with a powerful root system.
  • Feed aquarium pets dosed. Remove from the aquarium fragments of non-eaten feed. The remaining food begins to be processed by bacteria, due to which the favorable environment for breeding the thread occurs in the container.
  • When starting a new aquarium, turn on the lighting only at 4 o’clock a day in the first three days, every day increase the day day for one hour. Do not add fertilizer to a new aquarium.
