. Generally, the aquarium lid does not need to be open. The aquarium itself is integrated with various equipment, such as filtration, oxygenation and so on, so there is no need to change water frequently. Moreover, when the lid is opened, harmful bacteria from outside may float into it, which may endanger the health of fish or lead to a large number of algae outbreaks. In addition, if there is a lid, the fish is not easy to jump into the tank.
of adding a lid? 1. Prevent jumping: The main purpose of adding a lid to a fish tank is to prevent fish from jumping. There are many reasons that cause fish to jump into the tank, which may be the fish's own problems or environmental problems, so in addition to adding a lid to prevent jumping into the tank, we should also pay attention to changing water and oxygenating, so as to avoid similar situations.
2. Keep the water temperature: Although the water in the fish tank is in contact with the air, it can increase the dissolved oxygen, but it also has some side effects, that is, the temperature will change with the temperature, and with the lid, it can play the role of heat preservation, so as to avoid the temperature affecting the growth of fish.
3. Control the illumination: With the cover, the illumination can also be controlled. Although the health of fish can not be separated from proper light, long-term exposure to direct light will accelerate the outbreak of algae in the tank, thus affecting water quality. Therefore, it is necessary to control the illumination, and special lamps for aquarium can be used to fill the light.
