How to get rid of a black beard in an aquarium. Blackbeard in aquarium

Many aquarists face such a problem as a black beard in an aquarium. Ugly black plaque, bunches of fine hairs cover everything: plants, soil, jewelry, snags, glass. Why does the black beard aquarium strike?

How to get rid of this scourge?

What is black beard? Compsopogon coeruleus is a multicellular alga in the form of black and brown fine threads that can reach a length of 5 cm.

It usually affects higher plants, but can attach to any surface.

This alga breeds at a high rate and can cover all the plants in the aquarium. From it is very difficult to clear the snags and ornaments.

Methods of dealing with a black beard in an aquarium can be different, but it can be completely difficult to get rid of it completely.

Black beard in an aquarium usually appears after buying new plants or decorations. Therefore, it is very important to prevent the appearance of this trouble.

Spores of this algae do not spread through the air.

After buying new plants, they need to be kept in quarantine for several days. With the appearance of black bloom on the leaves to use such bushes are not worth it. Also, new plants can be treated with solutions of bleach, potassium permanganate or hydrogen peroxide.

Keeping the plants in a disinfecting solution needs only a few minutes (for delicate species, the time can be shortened), then rinse them in cool running water.

Of great importance is the condition of the aquarium. If the biofiltration is violated in the tank, the owners neglect the rules of care, do not change the water, do not siphon the soil and overfeed the fish, then the risk of the appearance of a black beard increases.

In an aquarium with a balanced balance, algae will not multiply and quickly disappear on their own. But in the problematic beard will appear again and again.

Therefore, it matters not only how to get rid of a black beard in an aquarium, but also how to prevent its recurrence.

How to get rid of algae black beard? The most radical method of dealing with a black beard is to completely restart the aquarium.

All fish need to be transplanted into a temporary container of a suitable size, provide them with filtration and aeration. Drain all the water completely, get the soil, plants, equipment and decorations.

The soil must be calcined in the oven or boil in boiling water. Jewelry and driftwood should be thoroughly cleaned from black deposits and disinfected with chlorine, potassium permanganate, peroxide or boiling water.

Do the same with all the equipment. The walls and bottom of the aquarium should be treated with boiling water, since it can be difficult to completely wash out the bleach.

Affected plants are best thrown away. If you want to save them, then tear off all the blackened leaves, process the bushes with a disinfecting solution, rinse well.

Put them in a quarantine container and make sure that the new deposit does not appear.

After everything is cleaned and disinfected, you need to perform the procedure to start the aquarium. To speed up the process, you can take water from a healthy aquarium.

Restarting the aquarium is time-consuming and responsible. Before you decide on this method, it is better to try to get rid of the problem by other methods.

In our problem will help and plants. How? You can get rid of a black beard if you suppress simple algae with the help of competitors – higher plants.

Fast growing species such as valisneria, hygrofila, lemongrass, elodea will do.

For their rapid growth need to create suitable conditions. For the violent growth of higher plants carbon dioxide is necessary.

If you do not want to buy a special installation, you can make it yourself using an ordinary plastic bottle.

Seedlings will need a lot, they need to fill a large space. You can buy green mass not only in the pet store.

At the local forum, you can ask aquarists to share plants after weeding.

As plants grow, they need to be cut and rooted cuttings obtained. Young shoots intensively absorb nutrients.

A sign of a close victory over a black beard is the acquisition of a white coloration by it. Shortly thereafter, the alga will die and begin to disappear.

One of the popular methods of dealing with a black beard – chemical. Boric or brown acid, antibiotics are applied.

But remember that such methods can lead not only to the disappearance of the black beard, but also to the death of all plants and even fish.

If there are no live plants in the aquarium, you can try to destroy the black beard with the help of Furacilin. This antiseptic is usually rinsed throat with sore throat. This tool destroys all algae.

The drug is lethal for shrimp, snails and some fish, such as corridors. Apply a similar method can be if you have a small aquarium without plants, populated by simple fish.

  • An aquarium with a large number of aquarium plants, algae will still be there, but they will not grow rapidly.
  • Good aeration of water – high oxygen content inhibits algae growth.
  • Filtration and mixing of water to remove organic residues and nitrates
  • Full coverage – no more than 12 hours a day, and with sufficient power.
  • A moderate number of fish in the aquarium, with a large number they create nitrates, which do not have time to digest plants.
  • Fish that feed on algae – molly, antsistrusy, loricaria, CAE (Siamese algae), ottsinklusy, hirinoheylus.
  • Moderate feeding, rotting food residues – the main supplier of nitrates.
  • Regular cleaning of the aquarium and replacement of the water.

The nitrogen cycle has not yet been established in newly launched aquariums, and the probability of an algal outburst is especially high in them.

By itself, the appearance of algae in the new aquarium – is normal. In the first 2-10 weeks since the launch of the new aquarium, you can see the rapid growth of brown algae. This happens if the level of nitrates in water exceeds 50 mg per liter.

Filtration and partial replacement of water solve this problem.

As soon as the plants take root and grow, they will take food away from the algae and the growth of the latter will slow down or stop. In a well-established aquarium, there is always a struggle for balance between plants and algae.

Fish that help fight algae in an aquarium:

  • Ancistrus
  • SAE
  • Ototsinklyus
  • Gerinoheylus
  • Brocade pterigoplicht

In addition, the plant snail neretina perfectly cleaned.

Located in most aquariums in the form of green dots or green film. These algae love a lot of light.

Green algae grow only if the amount of light and nitrates exceeds the level that higher plants can absorb. In densely planted aquariums, green algae develop extremely poorly, since higher plants consume nutrients and absorb the light necessary for the rapid growth of green algae.

Without condemning the use of plastic plants in an aquarium, I note that living plants look better and create the conditions for the normal development of the entire biosystem.
However, they can massively develop in aquariums with CO2 systems, due to fluctuations in carbon dioxide levels during the day. An outbreak of green algae growth can occur suddenly, especially when the level of phosphates and nitrates in the water is elevated. Usually they look like green dots covering the surface of the glass and the bottom of the aquarium.

The recommended countermeasures are reducing the amount of light and the length of the day, and mechanical cleaning is done with special brushes or a blade.

Mollies and somas, for example, ancistrus, eat green algae very well, and I keep a few specially for this purpose. The snail neretina also copes well with xenococus and other algae.

Brown algae grows quickly if there is too little light in the aquarium. They look like brown bloom covering everything in the aquarium.

Usually plants loving light are in poor condition or disappear. Plants that tolerate blackout well, such as Javanese moss, pygmy anubias, and other types of anubias, can be covered with brown foil; tough anubias leaves can be rubbed to get rid of brown algae. Again, aquarium cleaners, antsistrusy or ottsinklyusy will help well.

But the simplest solution is to increase the intensity and duration of daylight. Usually brown algae quickly disappear, one has only to bring the lighting in order.

Brown algae are very often formed in young aquariums with an unsettled balance (younger

3 months), with the wrong spectrum of lamps and with too long daylight. An even greater increase in daylight hours can lead to even worse consequences.

Blue-green algae are colonies of bacteria, and by this they differ from other types of algae. They look like a green, slippery film covering soil and plants in an aquarium. In the aquarium, they rarely appear, and, as a rule, in those who are poorly cared for.

Like all bacteria, they secrete substances that adversely affect plants and fish in the aquarium, so they must be carefully controlled. How to deal with blue-green algae in an aquarium?

As a rule, antibiotic bicillin or other types of antibiotics are used in the fight, but you need to work very carefully with it, you can irreversibly affect all inhabitants of the aquarium. It is better to try to bring a balance in the aquarium, carrying out a large replacement of water and cleaning.

Algae in the aquarium are a sign of an established biobalance. They appear on plants, stones, glass walls, and even on equipment. However, their rapid growth means that fundamental changes are taking place in the aquatic environment.

In an aquarium where there are a lot of plants, algae will not appear in large quantities. Good aeration and water filtration will stop their growth. Timely removal of food residue and dirt contributes to the purity of water.

If you notice that brown formations appear in the reservoir, it means that brown algae have settled in it. How to get rid of kelp and suspend their reproduction?

The origin of brown algae, symptoms of formation

If you notice that brown algae appeared in a newly launched aquarium, and they began to spread in large quantities, then the fight with them will be easy. Observe the correct mode of maintenance of the tank, and in 2-3 weeks the problem will be solved.

Carry out regular cleaning of the aquarium, change 20-30% of water once a week. When aquarium plants begin to grow, the algae will disappear due to the large amount of dissolved oxygen.

When an algae outbreak happened in an aquarium with “old” water, it is necessary to replace water already 2 times in 7 days, changing 30% of the volume of water. When replacing it is necessary to thoroughly clean the tank from excess food, waste products of fish.

Use a scraper to clean the glass of the aquarium, wipe the bottom, clean the decorations and plants with a toothbrush or a clean sponge.

Check the degree of contamination of the filter, if the filtration rate has decreased, then the filter is clogged. Clean the filter, but do not change its contents.

Reduce the length of daylight hours to 6 hours a day for several days, and the next 2 weeks bring it up to 10 hours gradually. If the lamps work for 1 year, it is better to replace them with new ones, but not all at once, but in turn.

Brown scurf appears in the tank in a week, and it takes almost a month to fight it.


There are chemicals that can affect diatoms. Some funds worsen the situation, delay the reproduction of beneficial microorganisms, from which the fish will suffer.

Drugs that can help with the removal of brown plaque, should be used according to the instructions. Be careful and cautious – some chemicals can harm not only parasites, but also plants with fish.

  • Tetra Algetten – drug in the form of water-soluble tablets, used for the prevention and destruction of algae. It dissolves gradually over a month, the number of parasitic formations decreases gradually. After 4-7 days, the first changes will be noticeable. Dosage – 1 tablet per 10 liters of water.
  • Sera Algovec – the tool destroys all types of algae in the aquarium. Dosage: 5 ml per 20 liters of water. After applying the drug, it is necessary to slice away all dead residues mechanically, there should be good aeration in the water.

Black scurf on plants can appear as a result of infection with the so-called “black beard”. This is a dark brown alga, which covers the leaf plates of plants, soil, glass and decorations.

Thin threads of dark shade on plants does not look aesthetically pleasing. Blackbeard can damage the plant, causing it to fade quickly.

The alga is rapidly spreading, and it is hard to fight it. Some chemical means and dimming of the light can give a partial result, but do not eliminate the root of the problem. For the destruction of the beard need to include comprehensive measures.

The first thing to do is regularly update the water, from 10 to 25% of the total volume of the aquarium. There should be no nitrates and phosphates in the water; make measurements with indicators before pouring into the aquarium.

The second procedure, which will help to eliminate black scurf in the aquarium, is to clean the soil from the remnants of food, to clean the dead leaves of plants. Next, you should increase the power of lighting up to 1 W per liter of water, turn on the light for 12 hours.

Additional help will be provided by some species of snails and fish that can clean the aquarium from algae and their livelihoods.

It is important to control the proportions of the feed: if you give the fish more food, then the non-eaten remains will dissolve, the level of ammonia in the water will increase. You can plant in the ground fast-growing plant species that absorb nutrients well.

The first sign that the alga dies off – changing its color to faded. Over time, the affected beard will disappear.

The universal remedy for aquarium black beard is on sale – it is JBL Algol. It in a few days will destroy fouling that formed on the surfaces.

To make the drug in the tank according to the instructions.

It is considered to be completely impossible to remove from the aquarium a dark bloom in the form of a black beard, but there are a number of additional measures that will help reduce its growth. The main thing is not to settle a lot of fish in a close tank. To oppress the beard, you can use the supply of CO2 (carbon dioxide).

In order to avoid infection by this pest, when buying a plant, carefully inspect its stalks and leaves. The slightest swaying of black beard hairs and brushes when moving or submerging in water indicates that it is impossible to buy a plant.

If conservative methods of dealing with black bloom do not help, then serious measures should be taken:

  1. Transfer the fish to another, previously prepared aquarium.
  2. Pull out all the plants along with the ground.
  3. Rinse the soil thoroughly under water, then boil it or calcined in an oven at 300 degrees Celsius.
  4. The aquarium walls should be washed and wiped with cotton wool dipped in potassium permanganate solution, then washed several times with glass.
  5. Start the aquarium again, having examined all the plants. Affected areas of the plant can be removed. Or take their uninfected shoots, re-plant in a separate container and grow.
  6. It is better to plant new and healthy plants in the newly launched aquarium.

See how to get rid of black beard.

There are so-called “biological” ways of dealing with harmful algae.

  1. Reduce the number of fish in the tank, you can distribute them to different aquariums.
  2. Turn off filtration and aeration. After that, the remaining organic matter in the water gets on the black beard tassels.
  3. If snails live in the aquarium, they should be removed immediately. The fact is that on their shells a beard feels fine. Reinfestation of the aquarium may occur. You need to take melang from the aquarium at night, when the snails crawl and sit on the aquarium walls.
  4. Temporarily do not feed fish with dry feed. During the fight against parasitic alga, do not give your pets even branded feed in the form of flakes or tablets. It is advisable at this time to feed them with live, washed food (bloodworms, pipeworm, pipe worker), or frozen daphnia. Portions should be such that the fish eat them in 3-5 minutes.

  • Take the scraper and clean the walls of the tank with it. If at this time in the water there are snails of other species – coils, then they will quickly eat the fallen tassels.
  • Remove black soil from the aquarium. Repeat these steps each time you clean the tank until you see obvious improvements.
  • Make frequent water changes – every day from 10 to 25%, depending on the volume of the aquarium.
  • Daily siphon the soil, removing the remnants of the destroyed algae.
  • After a few weeks, you will notice that the beard has disappeared.
