Filamentous algae in an aquarium

maintenance, care, compatibility

Filamentous algae often become the main cause of the rapid greening of water in an aquarium. This type of protozoa is actually a large group of algae, their active growth has a negative effect on aquarium plants.

It is necessary to fight with filamentous algae immediately, that is, at the very beginning of their appearance in the aquarium and this can be done in several simple ways.

Filamentous algae are different clusters of fairly long or short filaments. Separate beams can be formed from them, fine algae are perfectly attached to the bark, entwining higher aquarium plants, filter tubes and other equipment.

The color of these algae is most often green, but protozoa can also occur with a brown, black, gray and even reddish color. A small amount of filamentous algae is considered a normal phenomenon, and it indicates that it is more likely that breeding conditions in the aquarium are suitable for other plants. But a huge number of filamentous growths can bring a lot of problems, and, above all, they include:

  • The excretion of toxic substances by algae residues, which have a detrimental effect on the inhabitants of the aquarium. The natural death of a large number of filamentous algae leads to a continuous process of their decomposition, as a result of which toxins are released.
  • Algae strands entangle the plants growing in the aquarium and thus interfere with their growth and development.
  • The algae retain the remnants of food and other organic matter, and this leads to rapid contamination of all the water in the aquarium.
  • In bundles of filamentous algae, small fish and fry may become entangled.

In connection with these problems, it is always necessary to fight fast-growing filamentous algae in an aquarium, and both the simplest methods and certain professional techniques can help.

Filamentous algae multiply rapidly enough in the aquarium and begin to occupy almost the entire area under the following conditions:

  • Bright light. Thread often appears in those aquariums that are exposed to direct sunlight during the day or artificial lighting is used for more than 8 hours per day.
  • Insufficient oxygen supply.
  • Small amount of aquarium plants. The surplus of trace elements coming with fertilizer, with a small number of plants, has a positive effect on the rapid growth of the yarn.
  • Irregular replacement of water in the aquarium and its poor cleaning leads to the accumulation of nitrates, which are especially needed for the growth of nitrate.

Often the filament appears at the very beginning of breeding aquarium fish and this is due to the fact that higher plants have not yet had time to settle down, which means there is an excess of trace elements necessary for the growth of protozoa. Sometimes filamentous algae can be brought into the house and together with the plants acquired in pet stores.

You can fight with nitchatka by simply removing it or using special tools. Thin algae are easily removed from the water with the help of a stick with a rough surface on which they must be wound.

Some aquarists use a clean toothbrush for this purpose. In addition, it is necessary to create those conditions in which the thread feels itself is not the best way.

  • It is necessary to reduce the brightness of the lighting. If the aquarium is in bright sunlight, the glass should be covered with white paper or gauze.
  • The needle thread dies quickly if you create a specially artificial blackout in the aquarium for about three days. That is, on top of the aquarium should be covered with a dark cloth.
  • You need to install good filters.
  • The water in the aquarium should be replaced, and all plants, stones, appliances, rinse.
  • In the aquarium should be more plants. The more plants in the water, the less nutrients the algae gets.
  • Algae hunt some species of fish. These include molly, loricaria, antsistrusy, Siamese algae, girinohaylusy. Excellent cleanse plants from algae snails neretiny.

The listed methods of struggle usually help to restore balance in the aquarium. If these methods do not help, then you can purchase special chemicals.

The most commonly used tool is Tetra Algumin, it must be used strictly in accordance with the instructions.

Before you buy an aquarium for the first time and its inhabitants, it is always necessary first to know which plants are recommended for planting in the ground, which equipment and what conditions are considered optimal for the growth and development of all living things. This will avoid the most blatant and common mistakes that affect the appearance of filamentous algae.

Filamentous algae is a true aquarist nightmare. Barely appeared in the aquarium, these thin green strands, like hair, braiding plants and stones, begin to grow rapidly.

In a matter of days, they can flood the entire room reservoir, and it is very difficult to get rid of them.

Growing, the algae emit an excess amount of waste into the water, entangle plants, interfering with their growth. The algae stuck to the remnants of food, fish fry may get confused.

All this leads to active processes of decay in the aquarium, and if the process is started and nothing is done with it, even lead to the death of the bio-system.

First of all, you need to understand that algae and aquatic plants are completely different things. Plants are higher, complexly organized beings, they have different departments in their structure: root system, stem, leaves, shoots.

Each organ consists of its own type of cells. Algae, lower, protozoa, are much more primitive in structure – they have no division into organs, and they consist of only one kind of cells.

But in these cells complex biochemical processes take place.

Algae are not some kind of harmful parasites, they are a normal member of the aquarium community. To a greater or lesser extent, they are present in every aquarium.

Even the sterilization of all possible does not guarantee that you can get rid of algae. They will get there on the leaves of plants, or simply with tap water, which in the summer may contain spores of simple algae.

Aquarium is a biosystem model, and algae also occupy a niche in it. They are part of natural balance.

Green filamentous alga, to a certain extent, is a competitor of plants. If conditions for plants are optimal, they eat well and grow, there is no excess of nutrients and light, then they suppress the algae.

If these conditions are violated in some way – the algae “raise their heads”. The appearance of an undesirable resident is an alarming signal that the balance in the aquarium is disturbed, and only by restoring it can you reduce the growth of algae and get rid of them, at least from their excessive presence.

“The enemy must be known in person” – this also applies to algae. The fact is that under this name many species are collected, which can often be distinguished only under a microscope.

And to deal with them to be different methods.

Here are the main signs by which it is possible to determine with confidence that these are really green filamentous algae.

  • Appearance: thin green threads.
  • Texture: soft, slimy to the touch. When removed from the water, they immediately lose their shape and sag.

The filament is often referred to as a kladofora, but this is a misconception. The cladophora has a hard, elastic texture that practically does not lose shape in the air.

Green filamentous algae feed and grow due to substances dissolved in water and the process of photosynthesis occurring in the light.

Thread (Green Hair Algae, Hair / Thread Algae, Fuzz Algae)

Chlamydomonas and Chlorella. (Green water, Algae bloom, Green tinted water, Euglaena)

“Water blooms” is called the process of rapid growth of these algae. In summer, this happens in all freshwater bodies: the water becomes muddy, green, and thin green threads float in it.

The reason: the simplest unicellular algae, actively breeding and freely floating in the water.

And if for natural reservoirs it is a part of the natural life process, then for an aquarium it is a real disaster. Most of all these algae harm the plants, shading them and taking food.

Strictly speaking, unicellular algae are not filamentous – they are even more primitive in structure. However, in aquarium terminology, these species are often combined.

The fact is that in the mass single-celled cells can be combined into groups and threads, their texture, growth conditions, damage to the aquarium and methods of control are very similar to filamentous ones.

Flowering water – a sign of over-light and pollution of the aquarium. To cope with this process, it is necessary to shade the aquarium for several days, adjusting at the same time a powerful and smooth operation of the compressor. But even if the algae disappeared from these measures, a water change can cause a new outbreak, and the procedure has to be repeated.

Therefore, the only way would be to use a diatom filter or a UV sterilizer.

Chemical method of dealing with unicellulars – bitsillin-5, penicillin. Well helps ozonation of water.

You can get rid of flowering in a natural way – Daphnia crustaceans feed on algae and clean the water for several days. The only problem with this method – from the aquarium will need to remove the fish that Daphnia happy to eat.

Causes of filamentous algae in the aquarium

Filamentous algae multiply rapidly enough in the aquarium and begin to occupy almost the entire area under the following conditions:

• Bright light. Thread often appears in those aquariums that are exposed to direct sunlight during the day or artificial lighting is used for more than 8 hours per day.

• Insufficient oxygen supply.

• A small number of aquarium plants. The surplus of trace elements coming with fertilizer, with a small number of plants, has a positive effect on the rapid growth of the yarn.

• Irregular replacement of water in the aquarium and its poor cleaning leads to the accumulation of nitrates, which are especially needed for the growth of nitrate.

Often the filament appears at the very beginning of breeding aquarium fish and this is due to the fact that higher plants have not yet had time to settle down, which means there is an excess of trace elements necessary for the growth of protozoa. Sometimes filamentous algae can be brought into the house and together with the plants acquired in pet stores.

Methods of struggle

Filamentous algae will surely appear in the pond if there is an excess content of water-soluble nitrogen and phosphorus compounds. Therefore, first of all you need to pay attention to the operation of the filter and lighting.

The blue light that favors the growth of the thread should be eliminated and replaced with a soft one.

The accumulation of ammonia compounds occurs both when the filter is clogged and when there are too many fish with an insufficient number of plants. Floating plants and such that grow rapidly (hygrophilic, vallisneria) inhibit filamentous algae, taking away their food. Of great importance is the concentration of iron in the aquarium.

It should not exceed the permissible dose of 0.2 mg / l.

Removing the algae from the aquarium with your hands, for example when settling in Spirogira, is almost the only method of control. It is very important to clean the plants from the floss and wash them, and take CO2 to the aquarium only during the daytime.

For all cleaning activities, many recommend to darken the aquarium for three days.

In some cases, the use of algaecides, such as, for example, Sidex, containing glutaraldehyde, is very effective. Hydrogen peroxide in an amount of from 6 to 10 mg / l and the filament are also incompatible.

Do not neglect the biological methods of destruction of algae parasites. Who eats yarn, so it is catfish, gastromysones, viviparous small fish, pesilias and mollies, as well as karzuby, jordanelles, Siamese epalceorinhoses.

They grow very well in water with increased hardness. The well-known famous blooming of water in swamps and artificial reservoirs is due to filamentous algae.

Unlike other aquatic plants, they have a specific sugary smell and a salty taste. I think that a normal person will not taste the swamp mud. We believe experts that the taste of Tina is sharp and astringent.

Filamentous algae live in all water bodies where there is no strong current. The chemical composition of scientists is not fully understood.

What is dangerous filamentous algae

Filamentous algae are different clusters of fairly long or short filaments. Separate beams can be formed from them, fine algae are perfectly attached to the bark, entwining higher aquarium plants, filter tubes and other equipment. The color of these algae is most often green, but protozoa can also occur with a brown, black, gray and even reddish color.

A small amount of filamentous algae is considered a normal phenomenon, and it indicates that it is more likely that breeding conditions in the aquarium are suitable for other plants.

But a huge number of filamentous growths can bring a lot of problems, and, above all, they include: Isolation of toxic substances by the remains of algae, which are detrimental to the inhabitants of the aquarium. The natural death of a large number of filamentous algae leads to a continuous process of their decomposition, as a result of which toxins are released.

Algae strands entangle the plants growing in the aquarium and thus interfere with their growth and development.

The algae retain the remnants of food and other organic matter, and this leads to rapid contamination of all the water in the aquarium. In bundles of filamentous algae, small fish and fry may become entangled.

In connection with these problems, it is always necessary to fight fast-growing filamentous algae in an aquarium, and both the simplest methods and certain professional techniques can help.

An algal flash is a visual indication of a violation (absence) of a biobalance in an aquarium. This is the loss of any link in the balance!

Alga Edogonium

This is the most common type of filamentous algae that attack an aquarium. At first it looks like green down, then like long green strings. When they occur, it is recommended to apply the above described methods of control.

As well as in the literature it is noted that this alga appears due to the lack of macro elements. Surprisingly, in particular, phosphates and nitrates (of which everything is derived).

There is a positive effect when adding them. In advanced cases, algicidal preparations are used.

Kladofora (popularly known as Kladofora thread)


It has branching and does not have long strings. As a rule, it appears in aquariums with poor filtration, poor water flow and the presence of stagnation zones, where it “blooms”.
It is possible to get rid of it by eliminating negative factors, by mechanical means (by hand) and algicide.
Spirogyra
This seaweed is very nasty and not only because it is slimy and green, but also because it grows with a geometric progression. It is difficult to withdraw – neither algaecide, nor SAE will help. It is difficult, but you can defeat it mechanically: by manual selection, by rubbing it with your fingers (it is fragile), by pulling out from the bottom.

As an additional measure of struggle helps: killing the light, fish and algae shrimp.
Rizoklonium

It can also be attributed to filamentous algae, because has a filamentous structure. As a rule, it appears in young aquariums, where the biobalance is not yet set up, which can be identically called the nitrogen cycle. This is not such a terrible seaweed!

It actually disappears after the establishment / restoration of the biobalance in the aquarium. Applies to it, all common methods of struggle are effective.

Most effective: water change and algaecide.

Algae in an aquarium, how to get rid of and fight with all their species

When keeping fish in an aquarium, you may encounter such a problem as filamentous algae. Green algae, which includes filament, parasitize on the leaves of plants growing in an aquarium, entangling them with their own threads.

Everyone knows that if there are changes in the environment of any organism, there is a threat of its existence. At this time, another organism, which is comfortable in this environment, begins to crowd out the first.

If there is a thread in your tank, the ways how to deal with it will not give the desired result until you eliminate the reason for its appearance.

Filamentous algae will surely appear in the pond if there is an excess content of water-soluble nitrogen and phosphorus compounds. Therefore, first of all you need to pay attention to the operation of the filter and lighting.

The blue light that favors the growth of the thread should be eliminated and replaced with a soft one. The accumulation of ammonia compounds occurs both when the filter is clogged and when there are too many fish with an insufficient number of plants.

Floating plants and such that grow rapidly (hygrophilic, vallisneria) inhibit filamentous algae, taking away their food. Of great importance is the concentration of iron in the aquarium.

It should not exceed the permissible dose of 0.2 mg / l.

Removing the algae from the aquarium with your hands, for example when settling in Spirogira, is almost the only method of control. It is very important to clean the plants from the floss and wash them, and take CO2 to the aquarium only during the daytime.

For all cleaning activities, many recommend to darken the aquarium for three days.

In some cases, the use of algaecides, such as, for example, Sidex, containing glutaraldehyde, is very effective. Hydrogen peroxide in an amount of from 6 to 10 mg / l and the filament are also incompatible.

Do not neglect the biological methods of destruction of algae parasites. Who eats yarn, so it is catfish, gastromysones, viviparous small fish, pesilias and mollies, as well as karzuby, jordanelles, Siamese epalceorinhoses.

For example, algae of the genus Aufwuchs (from German – growing on something), grow on solid substrates, such as rocks, in both fresh and salt water. Algae, especially green and diatoms, are the main habitat for small crustaceans, rotifers, and the simplest forms of life.

A lot of aquarium dwellers intensively feed on surfaces overgrown with algae. Lake Malawi cichlids are widely known as fish adapted for feeding on algae.

Examples of the type, Labeotropheus trewavasae and Pseudotropheus zebra, are very characteristic. They have hard teeth that allow you to tear off algae from rocks. Mollies seek algae glades and pluck them.

In the marine environment, algae are an important part of the nutrition of sea urchins, sea worms and chitons.

I stimulated fouling algae in my tsikhlidnik, to create a natural environment, and got the right amount of nitrica and diatoms. Thus, depending on the species of fish and habitat from the habitat, growing algae may even be desirable. Algae is an essential part of the diet of species such as mollies, African cichlids, some Australian fish, and soma, such as ancistrus or otocyclus.

Frequent water changes reduce the amount of nitrates in the water and reduce the growth of algae. In a well-balanced aquarium richly overgrown with plants, the balance of minerals is in balance, the surplus is consumed by plants and algae.

And since higher plants always consume more nutrients than algae, the growth of the latter is limited.

  • 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.

Or diatoms (lat. Diatomeae) a large group of unicellular algae. Mostly single-celled, although there are also forms in the form of colonies.

The main difference between diatoms is that they have a shell consisting of silicon dioxide. This species is very diverse, some are quite beautiful, but mostly look like two asymmetrical sides with a clear separation between them.

Fossilized remains indicate that diatoms appeared in the early Jurassic period. Now there are more than 10,000 different species.

In an aquarium, they look like brown algae, which cover all internal surfaces with a continuous film. Usually appear in a new aquarium or with a lack of light.

You can get rid of them like brown ones, by increasing the number and length of daylight hours. Also it is necessary to apply an internal filter with a carbon filter, to purify water from silicates.

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 – this is not all that grows in the water. So called lower, primitive photosynthetic organisms, often consisting of a single cell or several cells collected in colonies or filaments. They live everywhere in the aquatic environment.

They are distinguished from higher plants by the absence of developed organs: stems, leaves, flowers, and also the fact that throughout their history they lived exclusively in water, while the plants were formed on land, and only after that some of them returned to the water .

Higher flowering plants (as well as several species of moss and ferns) are planted to decorate and revitalize the aquarium, while algae, with the exception of a single species of decorative importance, enter the aquarium without our participation and reproduce in it just when the balance is knocked down and balance is broken. They form a suspension in the water, causing its turbidity or discoloration, or stick around all the surfaces in the form of fluff, bundles and balls of yarn, plaque, mucus and the like.

It is clear that their presence does not contribute to the beauty of the aquarium.

Diatoms are unicellular organisms that have a silicon shell in the form of a box, many of which are capable of movement. The significance of diatoms in natural marine ecosystems is simply colossal, since they constitute a significant proportion of plankton and form a huge part of the organic matter of the earth (about a quarter), and their shells after dying are the basis of sedimentary rocks.

But in artificial reservoirs they, like their counterparts from other departments of lower plants, are unwanted guests. Brownish or brown algae in an aquarium, forming a slimy coating, especially in poorly lit places, often near the bottom – these are, as a rule, diatoms. (By the word “brown” – we mean only color, not systematic belonging, since Brown Alga proper is a separate department of highly developed marine organisms with large bodies, thallus).

Their reproduction contributes to a pH above 7.5, high water hardness and a high concentration of nitrogen compounds. An outbreak of diatoms can cause an excess of sodium in water, which occurs, for example, after treating fish in a common aquarium by adding salt.

According to its structure, they are closest to higher plants. They form fringing fouling, bunches, balls and strands of thin threads or films of different shades of green color on aquarium glass, soil elements, plants, stones, snags, decorations or a green suspension, from which water becomes cloudy and changes color (the so-called water bloom).

In addition, the appearance of filamentous forms of green is often caused by the lack of macroelements – salts of nitrogen and phosphorus. The growth of higher plants in such cases slows down or stops completely, and the aquarium draws in greenish mud.

When describing the algae divisions, we intentionally described in such detail what conditions the representatives of each of them need in order to breed in an aquarium to a significant amount (there are always a small number of these organisms in the aquarium, but they do not spoil the beauty and do not interfere with other inhabitants). Obviously, in order to cope with the invasion of crimsons, diatoms, or their brethren, these conditions in the aquarium must be changed.

And the most important thing is to plant a large number of living higher plants and create conditions under which they can successfully compete with algae and thereby control their numbers. The following steps will help change the balance of power in favor of the plants.

GREEN ALGAE.

Not all green algae in an aquarium are parasites: some of them belong to decorative species (for example, sparkle). The reasons for the appearance of malicious green Aquarius becomes excessive lighting and a sufficient amount of nutrients in the water. They harm higher plants because they shade them and absorb nitrates and phosphates intended for them.

In addition, this species changes the gas balance of water, which leads to a violation of biological equilibrium. In order to overcome this lower vegetation, it is necessary to resort to the following methods:

1. Lighting. It is necessary to change the light mode.

It is necessary to reduce the intensity and duration of both natural and artificial lighting.

2. Water change. In order to remedy the situation, it is necessary to regularly change the water, as well as clean the soil.

It should be done daily, otherwise the situation will only get worse, since clean water can only increase the reproduction of green algae. This method is best used in the case when the minimum number of fish in the aquarium.

3. Ozonation of water. It is necessary to create a strong current of water using a centrifugal pump, and apply a strong oxidizing agent, namely ozone.

With the systematic use of ozone will give good results: soon the flowering of water will stop, and the biological balance will return to normal.

Seaweed – this is not all that grows in water. So called lower, primitive photosynthetic organisms, often consisting of a single cell or several cells collected in colonies or filaments. They live everywhere in the aquatic environment.

They are distinguished from higher plants by the absence of developed organs: stems, leaves, flowers, and also the fact that throughout their history they lived exclusively in water, while the plants were formed on land, and only after that some of them returned to the water .

Why do algae sometimes capture an aquarium?

The laws of nature are such that living organisms settle everywhere where suitable conditions exist for them. The main thing you need to live algae:

Obviously, all this is in any aquarium.

Algae compete with flowering plants for light and macronutrients. Since the latter are more complex and highly organized, in favorable conditions they triumph in this competitive struggle, restraining the growth of their more primitive microscopic ancestors, taking away their nourishment.

However, they are older, smarter, more hardy, patient and less demanding. These, of course, are not properties of their character, but features of biology.

Algae can form various types of spores and other structures that can survive adverse times, they need to illuminate a different spectrum, they have other, faster ways of reproduction. And if the conditions in the aquarium are not ideal for higher flora, there will certainly be purple, diatoms or cyanobacteria, which will not delay to take advantage of this.

There are several sections of algae with different colors depending on the pigments they contain. Next, we describe how the representatives of different departments in the aquarium look and what conditions cause outbursts of their numbers.

Diatoms are unicellular organisms that have a silicon shell in the form of a box, many of which are capable of movement. The significance of diatoms in natural marine ecosystems is simply colossal, since they constitute a significant proportion of plankton and form a huge part of the organic matter of the earth (about a quarter), and their shells after dying are the basis of sedimentary rocks.

But in artificial reservoirs they, like their counterparts from other departments of lower plants, are unwanted guests. Brownish or brown algae in an aquarium, forming a slimy coating, especially in poorly lit places, often near the bottom – these are, as a rule, diatoms. (By the word “brown” – we mean only color, not systematic belonging, since Brown Alga proper is a separate department of highly developed marine organisms with large bodies, thallus).

The development of a certain amount of diatoms almost always occurs in the first weeks after the launch of a new aquarium. In long-running aquariums, diatoms appear in conditions of insufficient – weak and short-term – illumination or light of the wrong spectrum, without a blue and red maximum.

Their reproduction contributes to a pH above 7.5, high water hardness and a high concentration of nitrogen compounds. An outbreak of diatoms can cause an excess of sodium in water, which occurs, for example, after treating fish in a common aquarium by adding salt.

This type of algae (although several species are meant by this name) is one of the most disliked aquarists because it is very difficult to fight. At first, these algae cover the edges of slow-growing plants, like Anubias, or grow in small bunches. Then they cover all the plants in the aquarium, giving it an ugly look.

For fish they are not dangerous.

Mechanically remove these algae is almost impossible. Blackout or chemistry with them, in principle, can be fought, but then they will grow back.

Some fish (siamese algae eater, for example) allegedly eat it, but on the condition that they are no longer fed.

Other algae species (filamentous, etc.)

These algae are of many species (hair algae, thread algae – filamentous algae, etc.). Hair algae, bright green color, grows on bunches of a ground, stones, etc. Easily removed mechanically or eaten by algae fish.

Thread algae, dark in color, grows in individual long threads. It is easily removed mechanically and usually serves as an indicator of excess iron in water (0.1-0.2 mg / l).

Algae growing on small islands on glass are considered normal for a plant aquarium and are easily controlled by scraping (be careful if you have a Plexiglas aquarium) using a razor or a special scraper. Usually this should be done on the front glass.

Fish, such as antsistrusy, etc., will help keep the glass clean.

What are the chemical means of struggle and how are they bad

There are several chemical agents for algae control. Most of them are adapted from fish farming, where you have to struggle with overgrowing ponds.

An example is simazine, which is available under various brands for aquariums.

Unfortunately, these drugs act on different algae in different ways and are not always effective. In addition, these drugs have a negative effect on plants, causing the death of some plants.

Such as kabomba or vallinsneria, in the case of using simazin, which affects the process of photosynthesis.

The main disadvantage of these drugs is that they do not eliminate the causes of the appearance of algae (excess nutrients for algae in the water) and, accordingly, they will appear again from the spores. The use of these preparations can be recommended, as the last available remedy, in cases when it is necessary to quickly get rid of the algae and then continue the fight in a biological way, as described below.

Other ways are disinfecting plants in bleach. Some use hydrogen peroxide to control certain types of algae.
