It's better to turn off the fish tank lamp at night.On the one hand, because fish also need to rest, the light environment will still affect them.On the other hand, long-term lighting will increase the risk of algae explosion, once the algae multiply in large quantities, it will not only make the water green, look ugly, but also affect dissolved oxygen, leading to the death of fish anoxia.
1. Fluorescent lamp: Fluorescent lamp is the most commonly used lamp for the fish tank at present. Its main function is to improve the appreciation of the fish tank and make it look more beautiful.If it is a grass tank or a sea tank, the light can also promote the photosynthesis of aquatic plants and release more oxygen.For some fish, it can also play a role of color enhancement.
2. Metal halide lamp: Metal halide lamp was more popular in the past. The light has strong penetrability and good color rendering effect. The light itself is closer to sunlight, so it can also release ultraviolet rays, which can play a role in sterilization.However, its versatility is not strong, completely inferior to led lights.
3, led lights: led lights are not only the mainstream choice now, and even in the future it is also good to use.This kind of lamp is relatively safe, can emit a variety of colors, and as a cold light source, it will not affect the water temperature.The only drawback to this type of lamp is that it costs too much, so more fluorescent lamps are used these days.
