Diatoms in an aquarium how to fight

maintenance, care, compatibility

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

Brown algae are representatives of the Diatoms Division (Bacillariophyta). They should not be confused with sea kelp (Phaeophyta), which includes kelp seaweed.

In an aquarium, these algae do more harm than good, and you need to fight them.

Diatoms form brown dust on the walls of the tank. It appears everywhere – and on the ground, and on snags, and on the filter, and on the glass, even on the leaves of plants.

Initially, the formation is almost imperceptible, but later it acquires a dark, saturated shade.

At the initial stage, this type of algae is easily removed with a scraper, even crushed from plants. If you dash through the decoration, then many dust-like particles will fall from it.

Dust can be wiped off with a regular cloth moistened with running water, but without the use of detergents and soap.

Watch a useful video on how to deal with diatoms.

But in a neglected reservoir, the struggle with diatoms will be difficult. Brown particles turn black, grow rapidly, forming a buildup on all surfaces.

The top layer is crushed, and the bottom remains. This is reminiscent of the ground surface, with brown algae almost invisible through the front glass.

The problem is that such diatoms negatively affect the health of plants and fish. Plants can not carry out photosynthesis, almost “suffocate”, and the fish do not get enough water from the water, they can get poisoned.

If you do not deal with the problem in a timely manner, the consequences will be disastrous for all living creatures.

Brown algae spread very quickly, the parasite cells from one plant quickly pass to the neighboring leaves. In addition, brown patina can be a substrate for another parasite – a black beard, which is derived even more difficult.

What to do in order to prevent the growth of algae in the aquarium and destroy them forever?

  1. The aquarium should be lighting 10-12 hours a day, no more. Do not place the tank in place of direct sunlight. Bacteria that are sources of algae multiply easily by light.
  2. The overpopulation of the nursery with fish is a source of nitrates that the plants do not have time to assimilate. If you have a lot of fish, the tank should be spacious.
  3. If there are such fish in the tank as mollies, Siamese algae, antsistrusy, loricaria, catfish ottsinklyusy, then they will help to fight with a brown touch, eating it. Also, algae love snail neretina.
  4. Do not overfeed fish, remove food debris from the bottom with a siphon or a net.
  5. Regularly replace your aquarium water with clean water once a week.
  6. If a nitrogenous cycle is not established in a recently launched aquarium, an algae outbreak is more likely. The process of forming a biological balance lasts 1-2 weeks, at this time do not settle there fish and do not make large water changes. If the water level of nitrates 50 mg per 1 liter, the water should be well filtered and replaced with a new one. Take measurements of water parameters constantly.

See how you can get rid of the brown algae in the aquarium with the help of Theodoxus snails.

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.

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.

How to get rid of the brown algae in the aquarium :: brown algae in the aquarium how to fight :: Aquarium fish

Tip 1: How to get rid of the brown algae in the aquarium

Sometimes walls, plants, soil and other accessories in the aquarium are covered with brown bloom. This is not only extremely aesthetic, but also dangerous for aquarium inhabitants.

If a similar situation has arisen, then measures must be taken urgently. The enemy of the aquarium is brown algae.

These are multicellular organisms that appear in the wrong light and an excess of organic matter.

The question “opened a pet store. Business is not going. What to do? “- 2 answers

  • Lighting aquarium, cultured algae, special chemicals against brown algae, a few catfish-tototsklyusov.

1. To combat brown algae, you first need to know the reasons for their appearance. Poor lighting, high nitrate levels in the water, high pH levels, too low carbon dioxide levels can all lead to the appearance of brown algae.

2. Oddly enough, higher plants, that is, cultivated algae, specially planted in an aquarium, can become helpers in the fight against brown algae. They will absorb all the nutrients dissolved in water and brown algae will not get anything.

3. To combat the aquarium enemy, it is necessary to use fast-growing plants effectively, you need to plant the entire area of ​​the aquarium rather thickly. It is necessary to create the right lighting for better plant growth, the light day should be about ten hours.

4. It is necessary to reduce the content of organic matter in the aquarium. To do this, it is important to regularly replace part of the volume of water and reduce the amount of feed.

Pets should eat all the food in about two minutes, the rest – the surplus.

5. It is extremely useful to settle a few catfish into an aquarium. They love to eat brown algae, and they are happy to help get rid of them.

Five sotomy-otsinklyusov able to maintain order in an aquarium of one hundred liters.

6. An emergency measure in the fight against brown algae may be the use of special chemicals. However, it is worth remembering that their effectiveness is temporary.

Such chemicals are sold at the pet store. A consultant can help you find the best option.

There are also special conditioners for water, they accelerate the growth of cultivated aquarium plants and improve their appearance.

The aquarium is a closed biosystem in which not only fish and plants are present, but also hundreds of species of bacteria and unicellular organisms. This list also has microscopic algae.

They multiply under certain conditions and in large quantities. The fact is that they greatly spoil the appearance of the aquarium and change the habitat in it.

1. Can often be observed on the glass aquarium green plaque seaweed. It is usually harmless if reproduction has not happened too much.

To remove it, simply clean the aquarium glass using a scraper. If you need to destroy the excess seaweed, it’s enough to let fish eat in the aquarium.

You can also temporarily dim the aquarium or make too bright artificial lighting.

2. If brown algae appears, this is a sign that there is not enough light. They usually appear in the winter when artificial lighting is not enough.

In the spring, they disappear by themselves. To combat such algae, you can use a scraper.

Cleaning is necessary a couple of times a week.

3. If an invasion has occurred in your tank seaweed, then it is a natural result of bad conditions. First you need to pay attention to the water. Reproduction usually occurs in dirty old water, which contains a lot of organic matter, nitrogen, phosphorus compounds, vitamins and trace elements.

Rapid growth seaweed may interfere with gas exchange reservoir. Water will also bloom.

As a result, many plants may die.

4. To fight them, first you need to optimize the habitat, remove the affected plants, install filters that have biological fillers. Be sure to provide round the clock aeration in the aquarium. In extreme cases, you can use special chemicals.

They are sold in almost every pet store.

5. If there is an excessive reproduction of brown seaweed, then a characteristic mucous deposit on the surface of leaves and stones will be formed. There are cases when these algae completely tighten the bottom of the aquarium.

For the fight, you can use the antibiotic erythromecin.

Somik-ototsinklyus – is a real “janitor” for the aquarium.

It is easier to deal with brown algae, if you find out the reasons for their appearance.

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.

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.
