Fish tank lights do not have been open, open 6-8 hours a day on it.Long-term lighting will affect the rest of the fish, which is not conducive to their growth.And the environment with too much light is more likely to cause algae explosion, algae reproduction will not only make the water discolored, looks very turbid, but also lead to reduced dissolved oxygen, affecting the breathing of fish.
1. Growth of aquatic plants: If aquatic plants are planted in the fish tank, turning on the light can promote its growth, and at the same time, it can better carry out photosynthesis, which can release oxygen and help to improve the dissolved oxygen in the water body.It should be noted that aquatic plants need special three-band tube lamps, and other lamps are slightly less effective.
2. Fish hair color: Many fish are not particularly bright in color when hatched. They will develop color during the growth process. There are many ways to induce it to develop color. In addition to feeding more shrimp meat, you can also use light to induce color.According to the different types of fish, we need to choose different colors of lights.
3. Bacteria: It is inevitable that there will be some bacteria in the fish tank, which may enter when feeding or changing water. Once they invade the fish body, they may cause the fish to get sick. If there is an ultraviolet lamp in the tank, it can also have a bactericidal effect, thereby reducing the content of harmful bacteria in the water and preventing the fish from getting sick.
