There is no radiation in the fish tank. It should be noted that the radiation here refers to ionizing radiation harmful to human body, not all radiation. Because any object with a temperature above absolute zero has radiation, which refers to the way it spreads heat, and common sunlight is a kind of radiation, not all radiation is harmful.
1. Filtration: Fish farming must have filtration equipment. There are two kinds of common filtration, one is physical filtration, the other is biological filtration. The main function of physical filtration is to discharge particles and dirt from water, which can improve the turbidity of water quality. The function of biological filtration is to decompose and transform the residual bait and fish feces into harmless substances in order to prevent adverse effects on fish.
2. Lamps and lanterns: Fish farming generally requires lamps and lanterns. On the one hand, lighting is helpful for viewing, and on the other hand, it can also promote the color of fish. It should be noted that the lamp can not be turned on all the time, and it is better not to use heat, which will make the water temperature difficult to control, which is harmful to the health of fish.
3. Oxygen pump: The oxygen pump is not a necessary equipment for the fish tank. If there are not many fish to be raised and the fish is not big, the oxygen consumption is not high. Filtration can play a role in supplementing oxygen without an additional oxygen pump. But if you raise large fish, oxygen consumption is relatively large, you need special oxygenation equipment.
4. Heating rod: In order to allow the fish to live through the winter safely, or to provide a more stable and warm environment for the tropical fish, it is necessary to install a heating rod in the fish tank to keep the water temperature in the tank not too low, but not too high, which will accelerate the metabolism and affect the growth of the fish.
