1. Does the fish tank germicidal lamp turn on during the day or at night The fish tank germicidal lamp usually turns on during the day and at night. Different from ordinary lamps, germicidal lamps do not directly irradiate fish tanks, because their light is ultraviolet rays, which will be harmful to fish health. Therefore, it is necessary to connect them with filtering equipment. Before the water flows into the filter box, it must be irradiated through the area of germicidal lamps, so as to play a role in sterilization. If you only open it for a period of time every day, the sterilization effect will not reach a better level.
2. What's the use of fish tank germicidal lamp1. Sterilization: The main function of germicidal lamp is sterilization. What it can eliminate is mainly bacteria. For most molds, it has no way, because this kind of lamp relies on the water flow formed by filtration to sterilize, and molds have adhesion and will not flow with water, so they cannot be killed. In addition, the germicidal lamp can't distinguish beneficial bacteria from harmful bacteria, so it may have side effects if it is turned on for too long.
2. Killing algae: The germicidal lamp also has the ability to kill algae. For algae, it only takes 1.2-40 seconds to eliminate them. The reason why the time is much worse is that the species of algae are different. Chlorella, a relatively evenly dispersed algae, can be killed quickly, but if it is a longer algae, the killing time will be much longer.
3. Insecticidal: Germicidal lamps can also kill insects. The insects here are not insects, because ordinary insects can't get into the fish tank, but refer to protozoa or small arthropods, which will die quickly after being irradiated by germicidal lamps.
