1. How to raise fish with tap water

Water is the basis for fish survival, and tap water is one of the most convenient water sources in our daily life. However, it is not easy to raise fish with tap water, because tap water contains a lot of chlorine and other chemicals, which can cause harm to fish. So, if you want to raise fish with tap water, how can you raise fish?

1: Buy some necessary equipment

There are some necessary equipment for fish farming, including water quality testing tools, filters and water pumps. Water quality testing tools can help you test the content of substances such as chlorine, ammonia and nitrates in the water so that you can take appropriate measures. Filters can purify water, remove impurities and harmful substances in the water, and ensure the healthy growth of fish. Water pumps can increase water flow and ensure sufficient oxygen in the water.

2: Pre-treat tap water

Before adding tap water to your fish tank, it needs to be pre-treated to remove chlorine and other harmful substances. A common way to do this is to use a water treatment agent, which removes chlorine and ammonia from the water while increasing the salinity and mineral content of the water to make it more suitable for fish survival.

3: Change water regularly

The tap water for fish farming needs to be changed regularly to keep the water clean and healthy. Generally speaking, it is more appropriate to change the water once a week, which can reduce the accumulation of harmful substances in the water and ensure the healthy growth of fish.

When raising fish in tap water, the number of fish needs to be controlled to avoid overloading the water quality. Generally speaking, only one small fish or a pair of medium-sized fish can be raised per liter of water volume. If the number of fish raised is too large, it will lead to insufficient oxygen in the water and deterioration of water quality, posing a threat to the life and health of the fish.

5: Pay attention to the breeding environment

When raising fish, you need to pay attention not only to the water quality, but also to the breeding environment. The fish tank should be placed away from direct sunlight and cold wind, and the indoor temperature should be kept appropriate. Fish need sufficient light and oxygen, so you can place some green plants around the fish tank to increase the oxygen content.

6: Provide fish with suitable food

When raising fish in tap water, you need to provide fish with suitable food to meet their nutritional needs. Different types of fish require different foods, and you can choose suitable food according to the living habits and taste of the fish. At the same time, be careful not to overfeed or feed improperly, so as not to affect the healthy growth of the fish.

in conclusion

Raising fish with tap water is a job that requires patience and skill. Only by mastering the correct method can the healthy growth of fish be guaranteed. The above are some methods and techniques on how to raise fish with tap water. I hope it will be helpful to you.

10. Fish breeding sterilization lamp

Fish farming germicidal lamps play a vital role in the process of fish farming in fish tanks. Whether you are a beginner or an experienced fish farmer, you will realize the importance of keeping the water in the fish tank clean and sterile. Bacteria and viruses often breed in fish tanks, which will threaten the growth and health of fish. Fish farming germicidal lamps can help us solve this problem.

What is a fish sterilization lamp?

Fish farming sterilization lamp is a kind of lamp equipment that uses the principle of ultraviolet sterilization. Through ultraviolet radiation, it can effectively inactivate viruses, bacteria and algae in the fish tank and improve the purity of water quality. This kind of lamp is usually composed of ultraviolet lamp tube, shell and power supply. It is portable and flexible, easy to install and use.

The working principle of fish sterilization lamp

The working principle of fish sterilization lamp is mainly to use the radiation effect of ultraviolet rays. Ultraviolet rays are divided into three bands: UVA, UVB and UVC, and fish sterilization lamps generally use the UVC band. Ultraviolet rays in the UVC band can penetrate the cell walls of bacteria and viruses, destroying their DNA and RNA, thereby achieving a sterilization effect.

When the water in the fish tank passes through the fish breeding lamp, the microorganisms in the water will be exposed to ultraviolet rays. Ultraviolet rays can quickly kill viruses and bacteria, preventing them from continuing to reproduce and breed. At the same time, ultraviolet rays can also inhibit the growth of algae and keep the water clear and transparent.

Advantages of fish sterilization lamps

Fish farming germicidal lamps have many advantages over traditional disinfection methods. First, fish farming germicidal lamps do not require the use of any chemical agents, avoiding the harm that chemical agents may cause to fish and aquatic life. At the same time, fish farming germicidal lamps have a significant sterilization effect and can quickly and effectively inactivate bacteria and viruses.

Secondly, fish farming germicidal lamps are easy to use. You only need to install the lamp in the appropriate position and connect it to the power supply. The lamp housing is usually made of waterproof material and can be safely used in water. The light source is stable and has a long life, which reduces the trouble of frequent replacement.

In addition, the running cost of fish sterilization lamps is also low. The low power consumption of UV lamps not only saves energy, but also reduces recurring expenses. Maintenance is simple, and only regular cleaning of the lamp tube and housing is required to keep it working properly.

Selection and use of lamps

When choosing a fish farming germicidal lamp, we should determine the required power and quantity according to the size and type of the fish tank. Generally speaking, 0.5-1 watt of ultraviolet radiation is required per liter of water capacity. If there are a lot of water plants or algae in the fish tank, the power of the lamp can be appropriately increased.

When installing a fish sterilization lamp, the lamp should be placed in the appropriate position of the fish tank to ensure that it can radiate the entire water body of the fish tank. The height and angle of the lamp should also be paid attention to to ensure that the ultraviolet rays can fully irradiate the water surface and bottom.

It should be noted that when using fish sterilization lamps, we should wear protective glasses to avoid ultraviolet damage to the eyes. It is also recommended to minimize the presence of people when the fish sterilization lamp is running to avoid the impact of ultraviolet rays on the human body.

Daily maintenance of fish sterilization lamp

The normal operation of fish sterilization lamps requires regular maintenance and care. First, we need to regularly check the working status of the lamp. If the lamp is found to be black, unevenly lit, or the lamp life is over, it should be replaced in time.

Secondly, we also need to clean the lamp tube and shell regularly. The surface of the lamp is easily contaminated with scale and dirt, which affects the radiation effect of ultraviolet rays. You can use a soft cloth and detergent to clean the lamp, and be careful not to bump or bend the lamp tube.

In addition, if the fish farming sterilization lamp is not used for a long time, it is recommended to dismantle the lamp and place it in a ventilated and dry place to prevent damage due to moisture.

Conclusion

Fish breeding sterilization lamp is one of the necessary equipment for fish breeding enthusiasts. It uses ultraviolet radiation to quickly and effectively kill bacteria, viruses and algae in the fish tank and improve the purity of water quality. Compared with other disinfection methods, fish breeding sterilization lamp has the advantages of convenient use, low operating cost and simple maintenance.
