Does potassium permanganate affect the culture of nitrifying bacteria

Potassium permanganate is a strong oxidizing agent that kills many microorganisms, including nitrifying bacteria. When culturing nitrifying bacteria, it is recommended to use filter media that does not contain potassium permanganate to avoid adverse effects on nitrifying bacteria.

Again, don't use it to grow nitrifying bacteria.

Finish. Even potassium permanganate.

All of them are oxidized, but there are still mn+2 and other generated, the same heavy metal ions, or can denature proteins, which is not conducive to the growth of nitrifying bacteria, and even kills nitrifying bacteria.

But when I thought about getting water, I should have left half a basin of potassium permanganate water and put down the tap water before I took it clean, and now I think about it a little uneasy.

Nitrifying bacteria is a kind of microecological agent widely used in aquaculture, which is very important for the purification of water quality in aquaculture water, and the use of disinfectants and antibiotics in the breeding system will have different degrees of influence on the activity of nitrifying bacteria. In this study, four disinfectants (potassium permanganate, copper sulfate, glutaraldehyde and 84 disinfectant) and two antibiotics (oxytetracycline and sulfonamide) were selected.

Potassium permanganate, ultraviolet rays, etc. will kill nitrifying bacteria, salt has an inhibitory effect on bacteria, but bacteria will slowly adapt, pay attention to keep the concentration of salt stable; Fish can use other drugs when they are sick, many drugs have little impact on bacteria, the best way is to add a **tank for fish treatment or new fish sterilization! Besides, it is not good to control the concentration of the large amount of medicine in the large tank, and the effect on the fish is not good, and some need high concentration of liquid medicine for a long time, and the water must be changed immediately, which also has an impact on good fish, and it is a big trouble!

The nitrification system is composed of water pumps, pipelines, filter tanks, filter materials and other hardware equipment plus living nitrifying bacteria. When using potassium permanganate disinfection, if the residual agent is bleached, then the water pump, pipeline, filter tank, and filter material can be reused, and the filter foam in the filter material is not easy to rinse, and it is generally replaced directly. Living nitrifying flora cannot survive and needs to be re-established.

Is it necessary to sterilize the whole tank in winter? Potassium permanganate is used for sterilization and vitamin C is used for reduction.

You've already raised fish, so there's no need to sterilize.

Salt cubes are sold in fish shops.

Why disinfect?

After two days, it is completely possible to release the fish, but it has to cross the water.

Fish farming starts with water! But knowing this reason, fish farmers are too anxious, anxious to put the fish into the tank, this is a common problem of fish farmers, I think you know so much about the steps of opening the tank to raise water, then I don't have to say more, you should have a number in your own heart, wait for two days, there are benefits.

You can release the fish, but you should pay close attention to the swimming of the fish, do not feed them at first, and gradually transition to the normal feeding state after you are familiar with the new water quality and new environment.

After draining the water, open the filter and put the salt. Three or four days later, the nitrifying bacteria and the fish were released.

No, in the case of slight potassium permanganate, there is no effect on nitrifying bacteria in the absence of hydrogen ions.
