Diatoms: where they grow, what is harmful, how to deal with them

The simplest diatoms are a special group of unicellular microorganisms that have adapted to extreme habitat conditions. A feature of these organisms is a hard silica shell, making them resistant to adverse environmental conditions.

Diatoms are often found in aquariums, significantly deteriorating the appearance of the underwater garden.

There are about 1,600 species of brown algae on the planet.

Algae cells consist of liquid protoplasm, which is surrounded by a durable silica shell-shell. The protoplast penetrates into all the internal cavities of the membrane, filling it, which leads to a rapid increase in the colonies of microorganisms.

The shell is studded with numerous thinnest holes, which ensures the exchange of substances with the environment and protoplast.

Representatives of diatoms have a different color, depending on the structure of the shell and the predominant pigments. Most of these microorganisms are brown or gray, but there are also dark green, almost black and even bright red.

To date, scientists have known 1600 different types of brown algae. There are protozoa in sea water and grow both at great depths and on rocky shallows, where the shore is washed by water only during a powerful tide.

Also found are freshwater forms that inhabit the benthos and can settle on various substrates. Freshwater algae most often cause problems to aquarists who struggle to get rid of these unwanted microorganisms.

The characteristics of brown algae are:

  • Chitin shell.
  • Reproduction cell division.
  • Color variations of diatom species.

Durable chitinous shell causes reproduction characteristics of diatoms. Most often, these microorganisms are divided into two halves, reproducing by cell division.

Under suitable conditions, when diatoms receive the nutrition they need, cell division and reproduction of the colony can proceed in an accelerated mode, and the simplest settlements increase in just a few hours. In particular, this process is noticeable in running aquariums, where algae cover all the substrates available to them.

With the advent of powerful microscopes, the study of the underwater world has intensified, and scientists have been able to describe and identify the smallest species, which consist of literally one cell and a nucleus.

The most common are the following types of brown algae:

  • Pinnula, which has an elliptical elongated flap with a noticeable roughness of the shell.
  • Cymbella. Distinguished by characteristic crescent-shaped folds.
  • Navikula. It has sharp boat-shaped sash shell with tapered ends.

Navicules are most commonly found in freshwater aquariums.

In freshwater aquariums, colonies of NAVIKUL are most often found, characterized by brown and brown color. Subsequently, actively growing, these algae acquire an already characteristic black color.

Dozens and hundreds of different diatoms can be found in saltwater aquariums, which are gray, brown, black and purple.

Without exception, aquarists faced with the problem of diatoms, which form on the leaves of plants, stones, decorations and glasses characteristic brown plaque. If at first it is not difficult to cope with such protozoa, and an aquarist can easily maintain the purity of the glass, decorations and plants, then as the biobalance deteriorates, the colony of protozoa only grows.

As a result, getting rid of black and brown plaque is becoming increasingly difficult.

To determine the presence of diatoms in the aquarium is not difficult. On plants, soil and glass appears brown scurf, which is dusty when it is erased with your fingers, sponge or scraper.

In the early stages of colony formation, diatoms can be easily cleaned from decorations and glass, but in neglected aquariums the bloom acquires a characteristic black color, layers grow at each other, and if the upper layer is still erased from the glasses, the lower corneous parts are fixedly attached to plants and scenery.

Causes of diatoms:

  • biobalance violation;
  • improper lighting;
  • a large amount of organic matter in the water.

Diatomies may appear in the aquarium due to biobalance disturbances.

The brown algae in the aquarium do not have any effect on fish and other aquatic organisms. But plants such a plaque will face rapid death, because the dense layers on the algae foliage stop photosynthesis.

If you do not take any action to restore the balance and mechanically do not clear the leaves of the existing plaque, the plants will soon die.

The propagation rate of diatoms is extremely high, so new leaves are literally struck with gray and brown bloom for several days, which is extremely difficult to get rid of in the future. In running aquariums, brown and brown patina becomes an excellent substrate for the appearance of algae that are difficult to rid of.

Therefore, it is not surprising that Vietnamese, black beard and other single-celled cells appear on the leaves and soil.

Brown algae are the companion of a young, just-run aquarium. However, later in the stabilization of the balance diatom colonies almost completely die, and all that remains for an aquarist to do is to wipe the glass of the aquarium with a sponge or a special scraper every few weeks.

The cause of diatoms in a young aquarium is a unsteady nitrogen cycle. Plants, being only planted in the ground, are not yet rooted and do not consume the required number of trace elements, respectively, in the water there are nitrates, nitrites, nitrogen and phosphorus, which leads to the development of algae.

However, later on, the external filter will reach its full capacity, root and start growing plants, the nitrogen cycle will stabilize, which will solve the problem with brown algae.

In running aquariums, where there is overcrowding, there is no quality filtration, and in the soil there is an excess of organic matter, algae and other protozoa quickly appear. The aquarist will need to restore the biobalance, siphon the soil, increase the green mass and regularly change the water.

Ideally, the aquarium should be additionally equipped with a powerful external filter that will reduce the content of ammonia, ammonium, nitrates and nitrites.

Aquarist needs to sponge the aquarium once every few weeks.

A frequent cause of the appearance of algae in an aquarium is a long light day. Immediately after launch, do not install it for 12 hours a day.

It seems to many that the more light plants receive, the faster they are taken into growth, and the whole system is stabilized. But in reality, too powerful and prolonged illumination leads to the development of algae and the appearance of a characteristic brown deposit on the glass.

Therefore, after the launch of the aquarium, you should set the daylight time for no more than 6 hours, after which it should be gradually increased by an hour and a half every week.

Algae in the aquarium can also form if fertilizer is improperly applied. Exceeding the doses of nutrients introduced, inexperienced aquarists invariably stimulate the development of protozoa, including diatoms.

You can feed aquatic plants only with appropriate quality lighting, supply of CO2 and a large volume of green mass. Fertilizers need to be very carefully, in small doses, gradually increasing the number of trace elements, while observing both the condition of the plants and the absence of unwanted algae in the aquarium.

In rare cases, brown patina occurs when using burnt fluorescent lamps. Over time, they burn out the spectrum, they begin to shine a dim white light.

In plants, photosynthesis is reduced, a lot of undissolved organic matter appears in the water, nutrient medium is formed for various algae, which immediately “lift their heads” and fill the entire aquarium.

The sooner the aquarist begins to fight algae, the easier it is to get rid of them. A brown bloom literally in 10 days can hit the entire aquarium, and you can get rid of existing problems in one and a half to two months.

A strongly neglected aquarium, where the biobalance is disturbed, is easier not to restore, but to restart, for which you have to drain all the water, clean the plants from contamination, wash and boil the soil and subsequently monitor the correct biobalance of the ecosystem.

It is much easier to prevent the appearance of algae than to try to deal with the appeared bloom. When starting the aquarium, it is necessary to ensure the correct lighting, to feed the fish moderately, it is not recommended to use any fertilizers.

These measures will eliminate the formation of organic matter in the soil. In the future, you need to monitor the condition of the filter, replace the water regularly and do not overfeed the fish.

With a burst of brown algae in an already stabilized aquarium it is necessary to increase the frequency of water changes up to 2 times a week, changing approximately 1/5 of its part. At the same time, it is necessary to siphon an aquarium in order to remove organic matter that rots in the soil and worsens the chemical characteristics of the water.

To prevent contamination of the aquarium, it is necessary to ensure proper lighting.

One can get rid of single-celled ones by increasing the filtration of water, for which one more external filter is additionally installed, and the existing equipment is cleaned, which will improve its performance. Duration of daylight is recommended for a couple of days to be reduced to 5-6 hours per day.

Subsequently, this time is gradually increased to 10 hours a day. If necessary, old fluorescent lamps that have been in operation for more than a year should be replaced.

Excellent help to cope with the brown algae fish ottsinklyusy and snails theodox. Siamese algae-eaters, various mollusks and girinohailus also feed on diatomies.

For a 100-liter aquarium, two Siamese algae-eaters will be sufficient, which in a week will be able to clear the plants and decorations from plaque. In the future, the fish will maintain the purity of the aquarium by eating the thread, deer horn and other algae.

For prophylactic purposes and to restore running aquariums, it is possible to use algaecides, which not only suppress the simplest, but also accelerate the growth of higher plants. It is only necessary to select the correct application rate of algaecides, which is calculated individually depending on the number of plants and the volume of the aquarium.
