The seller of tropical fish who is sick says that it can be cured with cephalosporin, but will cephalosporin kill the nitrifying bacteria in the aquarium?

Yes, antibiotics will kill most bacteria, and cephalosporins can destroy the cell wall of bacteria and sterilize them during the breeding period. It has a strong selective effect on bacteria, but has almost no toxicity to people. It has the advantages of broad antibacterial spectrum, strong antibacterial effect, penicillin enzyme resistance and less allergic reaction than penicillins. Therefore, it is an important antibiotic with high efficiency, low toxicity and wide clinical application.

Nitrobacterium preparation is a kind of treatment agent used to control the concentration of autogenous ammonia in aquaculture pond water. It is not only convenient to use, but also has an immediate effect, so it is more and more popular among fish friends. When in use, the agent can be directly dispersed in the pool, and the effect of removing ammonia can be exerted soon.

commercial nitrifying bacteria preparations can be divided into living bacteria and dormant bacteria, and fishermen can choose and use them according to their own needs. The former is made of living bacteria, and their activities can be seen under the microscope. The latter is made of dormant bacteria, but it can't be seen that they have the ability to move under the microscope.

Precautions

1. Don't use the disinfectant at the same time

In order to avoid killing the water-purifying bacteria, remember not to use the disinfectant at the same time. If the disinfectant or the medicine for treating fish diseases must be used, it is necessary to wait for at least one week before using the water-purifying bacteria.

2. Pay attention to adjusting the temperature suitable for bacterial growth

In the process of using water purification bacteria, it can be effectively controlled under the most suitable water temperature conditions, and of course its effect is also the most ideal. For example, photosynthetic bacteria can grow and reproduce normally in the range of 23-29℃. When the water temperature is lower than 23℃, their growth gradually stops, so the effect of using such bacteria in aquariums below 23℃ is poor.
