For the full development and growth of plants and fish it is necessary to ensure proper lighting in the aquarium. Light energy is an integral part of an aquarium with plants, it is photosynthesis and the ability of plants to consume nutrients from the water.
Without enough light, plants simply cannot grow. Aquariums with plants require from eight to ten hours of lighting, on average, during this time there is a full cycle of photosynthesis.
Aquarium uses 5 types of lamps: halogen, fluorescent, discharge, LED lamps and incandescent lamps.
Now the most common are special fluorescent lamps. Previously mainly used incandescent bulbs. Often, aquarists use discharge or halogen lamps to illuminate an aquarium, and some are confident that only natural sunlight can provide a healthy ecosystem in a domestic pond.
However, each of these technologies has its advantages and disadvantages.
one. Incandescent lamps were long and widespread as aquarium lighting and were considered universal. However, this type of lamp consumes 80% of its energy for heat generation, and only 20% to light.
A small useful factor makes their use ineffective.
2 Halogen bulbs give much more light than incandescent bulbs, but they have a significant drawback – lamps with a voltage of 220V burn out too fast, and halogen low-voltage lamps can be used only through a special current transducer. And in fact, and otherwise the operating costs for lighting the aquarium with halogen lamps are unreasonably high.
3 Fluorescent lamps Now common in aquarism due to its advantages over the two types of lamps listed above. They differ in power and radiated color spectrum. This type of lamp gives a diffused quiet light and much more economical than other lamps.
The disadvantage of such lighting is the mandatory connection of a fluorescent lamp through a special ballast device, as well as a decrease in brightness as it is used.
Now a new generation of thin linear fluorescent lamps with a diameter of 16 mm T5 lamps is gaining more and more popularity. Advantages of the T5 lamp (16mm) compared to a conventional T8 lamp (26mm):
* Increased light output;
* Up to 30% energy savings;
* Increased service life (20 thousand hours);
* Min. the decline of the light flux of 5% after 10 thousand hours of work;
* Smaller size.
four. Discharge lamps gained popularity among aquarists relatively recently. Their advantages include efficiency, as well as more bright luminescence in comparison with fluorescent lamps of the same power.
Among the disadvantages of discharge lamps: connecting through an additional ballast device, the allocation of a large amount of heat, between the inclusions of the discharge lamp should be an interval of 20 minutes.
five. LED bulbs or LED modern and promising source of light, is becoming increasingly popular in aquarium. They have very high luminous efficacy at a low unit power, which means reducing the cost of lighting your aquarium and reducing the amount of heat generated by the lighting.
While the cost of installing LED lighting for the aquarium in existing prices will be unreasonably high.
Depending on the type of reservoir, its characteristics and your tastes, the type of lamp to illuminate a home aquarium should be selected, but the most convenient and suitable option is still the fluorescent lamps used by most experienced aquarists.
Remember that in order to have a healthy aquarium with plants you do not need megawatts of light, but it should be sufficient for effective growth of aquarium plants.
note: One of the best ways to avoid algae growth in a newly created plant aquarium is to use minimal lighting for the first few weeks. Under the minimum illumination refers to the reduction of daylight hours to seven or eight hours, and if it is possible to turn off one of the lamps in your lamps.
By doing this, you give the newly planted plants time to adapt to the new conditions in your aquarium.
