Activity of plants and fishes in an aquarium directly depends on lighting. If it is chosen correctly, then and health of all organisms will be normal. And how to organize competent lighting for your aquarium what nuances need to be considered? About everything one after another.
Instruction
1. At the lighting device for an aquarium do not forget about the next important moments. For lighting use glow lamps and luminescent lamps. As for power, be guided, proceeding from it: 1-1.2 W/l for glow lamps and 0.4 W/l for fluorescent lamps.
2. Glow lamps well are suitable for many fishes and plants as their light is well acquired by plants, it also perfectly emphasizes coloring of fishes. However the efficiency of a lamp is only 5% of energy (the others 95 will be transformed to heat that is if you need to create illumination of an aquarium in 100 liters, then the lamp in 120 W will be required, and such not to lean against glass. Therefore take glow lamps and place it over an aquarium, so that light got on depth approximately of centimeters 10 (no more than 30 cm).
3. Luminescent dumps are more widespread, their efficiency is four times more, than at above-mentioned option and they are three times more economic. In shops you will meet various types of these lamps. When choosing pay attention to requirements of the fishes and plants living in an aquarium to a range of emitted light. If you keep in an aquarium only fishes, sea invertebrates and plants are not present there, then the power of a lamp and type of a luminescence will be decisive factors. If you hold both sea and freshwater plants, then here you have to organize by all means the correct lighting so that it influenced photosynthesis process.
4. If you suited an aquarium quite recently, then later few months you can draw conclusions on that, how correctly you chose for it lighting. For this purpose you look at plants with the extended stalk. Lighting is arranged well if leaves at plants of the normal size and color. In case leaves plants narrow, then can have a problem in the shortages of food or in too bright lighting. Introduce fertilizers in an aquarium if changes do not occur – weaken lighting. Also check the content in oxygen water. If saturation by oxygen at the beginning of light day is not less than 5 mg/l, evening of 8-10 mg/l, then everything is made correctly.
