Black Primer for Aquarium

maintenance, care, compatibility

Quite a large number of aquarists do not want to use synthetic materials. In addition, some natural black soils for the aquarium are not quite suitable. For example, basalt soil gives a grayish tint, which may not fit into the overall design.

You can use granite, but knowledgeable people note that this rock gives impurities into the water and can be magnetised, which is not a very positive quality. Shungite can have sharp edges, which is extremely dangerous for fish swimming along the bottom.

A great option for natural black soil for the aquarium is quartz. It is perfectly perceived by the inhabitants of the underwater fauna, does not increase the hardness of the water and is completely neutral to it.

Black quartz soil for an aquarium is a great alternative to sand, gravel or gravel, it has a smooth surface, which is a key factor in the safety of fish. In order to decontaminate the soil, before applying it is recommended to boil it for five minutes.

In addition, quartz is optimal for both fish and underwater plants that have the ability to develop normally, since their roots have unhindered access to oxygen.

Another advantage of black quartz soil is the fact that using it for the aquarium inhabitants creates an environment that is as close as possible to the real one, that is, to the one in which they used to live.

Soil is a substrate for vegetation, aquatic plants take root in nm. To fix the roots, to obtain nutrients, higher flowering plants, which include aquarium plants, can not without soil.

The soil is involved in the biofiltration of aquarium water. The colonies inhabiting gravel, sand colonies of bacteria, microorganisms, protozoa actively interact with water, maintaining the natural balance of mineral and organic substances.

Of course, important and decorative function, which performs a properly selected soil for the aquarium. The combination of textures and color shades creates a holistic look of the aquarium.

The color of the soil emphasizes the beauty of aquarium fish, highlighting their natural colors.

The color of the aquarium soil is not just a whim of an aqua designer. According to a common theory, black soil for an aquarium is not just a spectacular backdrop for most fish.

It is known from a school physics course that the color of a surface is due to its ability to absorb or reflect rays of a certain length. For example, a black primer for an aquarium is seen as black because it reflects black, absorbing everything else; and vice versa – the white ground reflects the full spectrum of rays.

The aquarium, which uses black soil, is liked by most fish and plants – especially impressive in such an aquarium are fishes of a contrasting color. As you know, some species of fish are actively disguised as the environment – in an aquarium with light quartz soil, the brightness of the color of such fish becomes less expressive and pale.

In addition, dirt particles are better visible on a light surface.

It is not enough to choose the right sand, it is equally important to correctly put it in the aquarium. Laying soil in an aquarium should help recreate the look of a natural reservoir.

It should be laid with a slope to the front glass in the aquarium. What’s the point of this?

Thanks to this simple reception, it will be easier to remove the dirt that accumulates in the recesses of the soil. The thickness may be different, but in the range from 3 to 8 cm.

In addition, in the front glass in the form of plexiglass sides it is permissible to build a small area that will be free of soil. In this place of the aquarium, a tubule or bloodworm can burrow.

For this purpose, a transparent glass vessel can be placed in an aquarium.

Soil for aquarium with fish and plants: the rules of preparation

Nutrient soil is extremely important to put in the aquarium. How to do it?

If you collected the soil for the aquarium with your own hands, did not purchase it in the store, then you need to prepare it. How to do it?

Rinse and boil. This is the so-called ground cleaning in an aquarium before it is placed.

It is necessary to prepare also sand, pebbles, bought in a pet store. It is enough to wash and process with boiling water.

An error will be washing with the addition of domestos or other chemicals. How can this affect the constancy of the aquarium?

The fact is that sand, pebbles are well absorbed by chemical compounds, it will be very difficult to wash them after processing, which means that they will gradually be released into the water.

After the selection of soil for the aquarium, it can be placed in the aquarium with fish and plants. You can do this immediately: rinse and still wet place in the aquarium.

Black, colored, quartz, as well as a different sand needs care. How to clean the soil in the aquarium, how to monitor its cleanliness? The soil for the aquarium, along with the plants must be periodically cleaned, in other words, siphon.

Externally, the siphon is a hose in which a vacuum is created and by means of which dirt is sucked in with water. Sand, pebbles need to be cleaned as it gets dirty.

Now you know how to choose sand, pebbles, how to prepare them, how to clean the soil in the aquarium and a lot of other useful information. One thing remains: choose the appropriate option and apply all the knowledge gained in practice.

Good luck!

primer for aquarium

Soil is one of the most important components of the entire aquarium biosystem. The nutrient base optimally selected in size and color for the aquarium not only improves its appearance, but also makes it possible to shade and even enhance the color intensity of its inhabitants.

In addition, it is the soil that is the substrate for many tropical plants. Here the roots are strengthened, and reproduction and nutrition take place.

For certain types of fish, black soil is a habitat. Mastocembel and macrognatus spend time, burrowing in the “ground”, with only inquisitive sharp faces sticking out. Such curious Barbarians are so accustomed to raking the bottom, that they get sick and even die without soil.

In addition, for almost all aquarium pets, the lack of soil is stress. In the “bare” aquarium, the inhabitants become nervous, are clogged in shelters and lose their color.

The soil for the aquarium is also important in view of the fact that for many genera and species of fish in the old manner remains a reliable substrate for spawning. Putting eggs to the ground and building nests in it is a favorite occupation for them.

Black or white primer – the basis of the filter layer; This is the most important part of the biosystem. Microorganisms that produce biological water purification and processing chemical compounds (harmful to inhabitants) settle on it.

Thus, the soil for the aquarium maintains eco-balance even in a closed volume.

The choice of the most suitable soil is not as easy to make as it seems: it depends on many factors. The first substrate (marble chips, building sand) is extremely forbidden for use!

There are cases when rare tropical fish died because of the owner’s amateurish approach to the choice of soil for the aquarium.

Sharp and large pieces of the substrate are dangerous for causing fatal injuries to your colorful pets, so it is recommended to use selected treated black primer, specially designed for aquariums.

Soil for an aquarium – types natural neutral artificial

How to choose a material for the soil substrate? All materials of which the ground for the aquarium is made can be clean or with admixtures of additives.

Peat can be added to the sand or gravel, which improves the nutritional properties of the soil. Peat perfectly holds elements such as anions and cations, pure gravel does not have this ability.

Sand and gravel as grounds for aquariums is a natural substrate that is also suitable for plants. The amount of fine gravel is from 2 to 5 mm, it has a low ability to retain nutrients. Good gravel secures the rhizomes of plants, put on peat.

Fine sand does not contain nutrients, absorbs them poorly, breaks gas exchange. It is better to use sand with other substrates (cake, rakushnyak, clay). If a bottom filter is installed in the tank, fine sand will clog the equipment with dirt particles.

It is better to use coarse river sand purchased from a reputable manufacturer. Do not choose sand saturated colors – yellow and red.

This substrate contains a large amount of iron, which is harmful to fish.

Aquarium clay soil – clay contains inorganic components, such as iron silicates and iron oxides. Some types of clay may have other components – copper, manganese, zinc, aluminum. They are required for plants, but in high concentrations have toxic properties.

A special property of clay is that it attracts positively charged ions of metals and salts. It also serves as an excellent fertilizer for vegetation.


Laterite is a tropical red earth consisting of iron dioxide. Laterite can be used as a bottom layer for soil.

It has a good ability to absorb nutrients.

Garden soil as soil for aquariums – garden soil contains many impurities. There is no guarantee that the land will be clean. In the land of a large number of fertilizers, parasite cysts.

It is saturated with nutrients, due to which the glass tank will quickly fill with algae. The land used for pot plants has a lot of organic matter and peat, it can be mixed with gravel and sand as an additive.

Peat – needed to soften the water. It consists of a mixture of organic minerals that are in a rotten state. Peat is added to aquariums, where plants and fish need humic acids.

In small concentrations, boiled peat is practically harmless.

Artificial plastic granules – a new type of soil that can satisfy many aquarists. The granules are of different shades, but the rich color may be too contrasted against the background of the underwater aquascape.

Remember that the substrate must be chosen closer to the natural color: gray, black, red-brown, white. Fish with bright body color will look great on this background.

See how to care for quartz sand in an aquarium.

Grounds for aquariums should be laid in three layers:

  1. The bottom of the aquarium is lined with laterite or clay mixed with gravel (the thickness of the lower layer is from 3 to 5 cm). You can add clay balls to the laterite, which will provide nourishment for new, non-adapted plants. Cables for heating the bottom should be laid in a glass tank so that the glass is not injured. Do not lay the heating cable in a shallow clay or sand substrate to prevent overheating.
  2. The middle layer should be slightly thinner – 3 centimeters, the substrate – sand or gravel, which can be mixed with a small amount of boiled peat. The thickness of the middle layer is recommended to put balls of clay.
  3. The surface of the ball is lined with fine gravel mixed with sand, which prevents water turbidity. On the top layer you can put decorative stones or corals, shells (if necessary). If there are pets in the aquarium digging the ground (catfish, cichlids, snails), then the top layer should be an order of magnitude thicker (5 cm), or the soil should be planted in pots along with broadleaf plants.
