all the time? You don't need to keep the lights on all the time. You can turn them on for 4-10 hours a day. The purpose of turning on the light is to let the fish receive light, which is very helpful to their health. If there are aquatic plants in the fish tank, it can also promote photosynthesis, thus releasing a certain amount of oxygen. If the light is on all the time, it will affect the rest of the fish, and it may cause algae explosion for a long time.
of turning on the light? 1. It is good for hair color: Many tropical fish need a certain amount of light in the process of growth, so as to show a good color, so they need to give the fish a certain amount of light. Different fish have different needs for light. For example, arowana needs white light, while goldfish can use red light.
2. Growth of aquatic plants: Light not only helps the development of fish, but also promotes the growth of aquatic plants. After all, aquatic plants are also plants, and photosynthesis is still very important. It should be noted that if there are no aquatic plants in the tank, the long illumination time can easily promote algae reproduction, thus changing the water quality.
3. Kill bacteria: Aquarium lamps also include ultraviolet lamps, which are germicidal lamps that can effectively kill bacteria in water and prevent fish from getting sick. However, it should be noted that the illumination time of the germicidal lamp should not be too long, otherwise it will destroy the nitrification system and affect the ecological cycle.
