SOLVIT oxygen in water. Eg at a temperature of 15  C solvit amount of oxygen in water is 10.06 mg / liter and at a temperature of 30  C will be 7.52 mg / liter of water. The minimum quantity of oxygen necessary for survival of fish is 3-3.5 mg / liter in winter and 5-5.5 mg / liter summer.
To ensure these values of oxygen in the water once the fish tank is too high, exceeding the capacity of oxygen plants, especially at night, we use aerators (vibrating).
The introduction of 1 liter of air per hour to 100 liters of water, get a SOLVIT oxygen enrichment of 3.3 mg / liter to a fine spray and 1.5 mg / liter air to spray a large bubble. The disadvantage of a powerful air pumps (large bubble) is that it produces large turbulence in the water, resulting in deposition of organic matter and silt, which will disturb the water continuously. To adjust the air flow using a valve (plastic) interposed, the hose, the air pump and spray nozzle, where we increase or decrease the amount of air transmitted. The valve shall have three branches, one of which is to remove excess air (pressure) created between the nozzle and pump, to no force components of the latter, removing a plant prematurely.
The amount of oxygen in water depends on atmospheric pressure of air, lowering the eve of a storm.
During the day or artificial lighting, as a result of assimilation clorofiliene and carbon dioxide to oxygen to water an important contribution and bring him and plants. At night the process is reversed, they consume a part of it may appear that a lack of oxygen would become lethal to plants and fish. Therefore the operation without interruption of the air pump is required, especially at night. Part of dissolved oxygen in the area of contact between air and water are transported deep eddy currents formed by the bubbles. In a liter of water, air volume SOLVIT 20-25 cm3, of which only 6.8 cm3 is oxygen. If this amount of oxygen falls below 0.5 cm3 per liter of water, then life processes cease.
LIGHTING Aquariums
A good quality lighting leads to a normal state of life both for fish and plant. The illumination is made by fluorescence lamps or natural light. Use in lighting incandescent bulbs, is obsolete because of efficiency, poor quality of light and the small number of hours of service they have.
Location of the aquarium for a natural lighting as well as intensity and number of hours, should be (if possible) on the north wall or on the opposite or perpendicular to the window. Another type of location is bad, because the vessel falling direct sunlight, especially leading to an overheating in summer water and abundant and undesirable development of different types of algae. To avoid this, we must have ready means of shading the container when the sun's rays fall directly on it. Fluorescence tube to illuminate, its power in watts to be equal tank volume in liters divided by four. Ex: 50 liters / 4 = 12 watts. Fluorescence tubes to measure the exact length of the vessel was mounted as close to the surface so that light falling from above and toward the viewer as to be screened. If we have caps, it must cover and clothe all the walls vessel up to 0.5-1cm above the water level and thus made and light shielding. If not benefit from such capacity, the screen can be achieved by sticking a black adhesive tape around the vessel walls, all in 0.5-1cm above the water level so that the light should not disturb the viewer's eyes. Water level in tank must be 2-2.5 cm below the top edge.
Duration of illumination is 11.12 hours on days when only in artificial conditions and the 8 o'clock and enjoys natural light. A continuous lighting (24 hours a day) eventually lead to changes and biological changes in fish body. Even if they do not like people sleeping at night, there is a state of somnolence, with a slowdown in metabolism, sleep-like state. Thus deprived of rest, will lead to illness, apathy, denial of food to slowdown and eventually to death, both fish and plant.

Creating a natural setting as with plants, terraces, or rocky caves, including our fish to swim with pleasure, stating their true colors in time aceelaşi are gifted, the ultimate goal of each aquarists.
Use stones as decoration or sets of stones in various forms, using the home as possible volcanic rocks (granite, basalt, syenite, etc.), polished on corners and edges too sharp not to wound the fish. Merge stone in the construction of caves or overlapping sets of rocks, can be done with cement (concrete = one part sand, two parts gravel, one part cement and water) after hardening, they will keep for two weeks in a vase of water, changed daily. But we can get these sets and the market for some exotic fish breeders, it consists in imitation of caves and terraces of clay, very useful if we have fish in the families Wels (health) and Cichlidae, which are used as hiding places or Instead of eggs deposited. The location of these buildings should be taken into account a possible breaking and falling of stones from glass fish tank or if it has scormonitori will take steps to balance their security against surpării over fish or eggs. Also often used as decoration and roots or branches of willow, alder, vine-vine, etc., mounted on the substrate but not before a slab or rot and boiling salted water for 1 hours. By boiling wood rot causing pathogens are destroyed and removed while the air is accumulated in the tissues, so that the wood is heavier than water.
In determining the number and manner of settlement of these sets, to take account of vessel size, requirements and number of fish species and plants that benefit. A fish of 7-10cm in length requires 5 liters of water for swimming. Usually, about 35-40% of the space of a tank must be free. Copies of selected plants must be neofilite and non-fragmented. Before planting will clean the dead leaves, attacked by diseases or snails. When planting in the aquarium, plants whose height and size is large or we will reach that high, are planted in the back of the box, and small in the middle of it.
The use of artificial plants (plastic) is unsightly and also have many disadvantages compared to natural:
 not consume carbon dioxide, which gathered in large amounts of water hardness value (DGH) and its acidity (pH). substances decomposing organic (food scraps, manure  not any oxygenate the water.
 color plastic is toxic and dissolve in water.
 gets a nasty issue, because the brown and blue algae deposited on them and is difficult to clean.
 do not meet our goal of creating a biotope as natural.

The natural environment and at the aquarium, the algae have a clear role, as long as their number falls within normal limits. As benefits have:
 in the process of photosynthesis, they remove large amounts of oxygen in water.
 are made up of important organic substances, thus becoming an essential food for some organisms in water and fish, which provides extra vitamins, water and carbon, mineral substances, microelements etc..
 order to develop and grow, they extract from the water a number of mineral elements, nitrogen and phosphorus compounds, carbon dioxide and other substances toxic to fish, helping to purify water.
Colonies of algae occur within 4-5 weeks after the start of the new aquarium and filed with the preferred vessel walls and objects in it. Developed in excess will give water a greenish hue, is not toxic to fish but sometimes unpleasant appearance and flavor of a mold.
Their appearance is enhanced by: a light too bright, artificial or natural, the presence of large quantities of
