How to choose a lamp for a house aquarium, each aquarian thinks sooner or later. Sufficient lighting guarantees normal activity and efficiency to all inhabitants of both a freshwater, and sea house aquarium.
Instruction
1. First of all choose the lamp type which is the most suitable for your aquarium.
2. The glow lamp is a flask in which the metal spiral with the electric current going on it shines. Such lamp for a house aquarium generates too much heat and gives too diffused light. Besides, its service life is pretty small. The only thing that still involves some aquarians in this lamp - it is its low cost.
3. The quite good tool for illumination of a house aquarium is the halogen lamp. The appearance it very much reminds the glow lamp. But on the action strongly differs from it. Halogen lamps for aquariums radiate very intensive light and do not give excessive heat. They are ideal for rapid growth of aquarian seaweed. The main lack of halogen lamps – their fragility.
4. The most popular light sources for house aquariums are the fluorescent lamps giving soft diffused light. The objects lit with such devices do not cast sharp shadows. Such lamps are capable to light rather big surface. In addition, fluorescent lamps very easily are installed and have rather high durability. The principle of their action is based that instead of a metal spiral the inert gas gone in a flask shines. Minus fluorescent lamps – decrease in their brightness in process of operation.
5. Rather recently in aquarium husbandry digit lamps began to be used. They are rather economic, and on the brightness exceed luminescent twice. Digit lamps generate a lot of heat. Their main shortcoming also consists in it.
6. When choosing a lamp for a house aquarium pay attention to its power. It has to correspond to the volume of the lit capacity (0.5 Watts on 1 liter of water). Remember that the excess of light can influence inhabitants of an aquarium negatively.
