How can you tell if nitrifying bacteria are dead in a fish tank?

If the cylinder wall is already very sticky and there are brown algae clusters in the corners of the cylinder wall, it proves that your nitrification system is in danger, the principle of the filter material is the same as above, look at the water color, the water color is transparent and clear, combined with the cylinder wall reaction, it proves that the nitrification system is good, if the water quality is white and turbid, black and yellow, or the green algae in the water has emitted a more serious fishy odor, the garbage on the filter cotton is piled up, and there have been bursts of musty smell, then your nitrifying bacteria are afraid that there is only the last breath left. Lying in the tank, refusing to eat, the fins have been partially melted, the fish body has serious redness, the gill cover opening force increases, and it is slightly difficult to breathe, then the water in this tank is very old, and a part of the new water must be replaced immediately to ensure the normal operation of the nitrification system.

Gently touch the wall of the fish tank with your hands, if the wall of the tank is clean and there is nothing sticky, it proves that the nitrifying bacteria in the tank have not formed. If there is stickiness on the cylinder wall, it means that there are nitrifying bacteria.

Do nitrifying bacteria in fish tanks die in a power outage? Will what netizens are worried about happen?

In the freshwater tank, nitrification is a killer of fish in the early days, and ammonia produced by ammonia has two different forms in water, one is ammonia and the other is amine. Ammonia is highly toxic, and amines are non-toxic. Ammonia and amines are converted into each other according to the pH value in the water, and the higher the pH, the higher the percentage of toxic ammonia contained in the water.

For example, when pH = 9, 25% of the total ammonia in the water is toxic ammonia, and at pH = 7, the toxic ammonia content is only 1% of the total ammonia. In acidic water, toxic ammonia basically does not exist, so fish will not be poisoned by ammonia, but under the action of nitrite bacteria, no can make fish poisoning, of course, no will not always rise, because nitric acid bacteria will follow.

Nitrification use. Nitrifying bacteria preparation is a treatment agent used to control the concentration of spontaneous ammonia in aquaculture pond water, which is not only quite convenient to use, but also can play an immediate effect, so it is becoming more and more popular among aquarists. When used, the agent can be directly spread in the pool, and it will soon be able to exert the effect of ammonia removal.

Commercially available nitrifying bacteria can be divided into two types: live bacteria and dormant bacteria, and fishermen can choose and use them according to their own needs. The former is made from the living organisms of bacteria, and their activity can be seen under a microscope. The latter are made from dormant bacteria, which cannot be seen to be motile under a microscope.

The advantage of choosing live bacteria is that the ammonia removal effect is rapid, which is most suitable for emergency situations where the ammonia concentration is too high.

However, because the requirements for oxygen are very strict for live bacteria, especially the bacteria of the genus Nitric acid bacteria can only survive in the presence of sufficient oxygen, because of this, it is often difficult to preserve the live bacteria and make products, so when purchasing such products, special attention should be paid to its effective use period, if expired products are used, there is no efficiency from the point of view of ammonia removal.

The advantage of choosing dormant bacteria is that they can be stored for a long time and there is no need to worry about failure, but because the activation time required to change from dormant bacteria to live bacteria can take several days, it cannot be used for emergency treatment, and it is only suitable for daily water quality management. Generally speaking, the shelf life of dormant bacteria is about 1 2 years, and it is still necessary to pay attention to the expiration date indicated on the product when using it, so as not to expire.

In addition, only bacteria of the genus nitrite can be used as a preparation for this product, so there may be excess intermediates that accumulate in the water after use, so that the concentration of nitrite acid will temporarily increase suddenly, but it will not have a significant impact on water quality.

The way to know if there are nitrifying bacteria in the fish tank: the reaction between the tank wall and the filter material, look at the water color, see the fish disease, and the egg white worms are all over the tank wall (round).

1. The reaction between the cylinder wall and the filter material

Touch the cylinder wall with your hands, the cylinder wall is clean and clean, and there is nothing sticky, which indicates that the nitrifying bacteria in the cylinder are not sound. If there is a feeling of sticky and thin layer, it means that there is still a certain bacterial film, which can at least prove that nitrifying bacteria are still there. The chalking of the filter material and the blockage of the voids are also not conducive to the survival of nitrifying bacteria, and the problem is found to be cleaned or replaced in time.

If the walls of the tank are already viscous and there are already brown algae blooms in the corners of the walls, the nitrification system is in danger.

2. Look at the color of the water

The water color is transparent and clear, combined with the reaction of the tank wall and the reaction of the fish, which proves that the nitrification system is good. If the water is deficient, the hidden matter is white and turbid, black and yellow. None of them are good.

In particular, the water has emitted a serious fishy odor, and the garbage on the filter cotton is piled up, and there have been bursts of musty smell. Then your nitrifying bacteria are afraid that they will only have their last breath left. First of all, it shows that the amount of melted oxygen in the water has begun to enter the trough.

3. See fish diseases

The fish began to shrink their fins, lie on the tank, and refuse to eat, the fins have been partially melted, the fish body has serious red blood capillaries, the gill cover opening force increases, and it is slightly difficult to breathe, then the water in this tank is very old, the water quality has begun to fall sour or the ammonia nitrogen in the water has exceeded the standard, and the reproduction rate of nitrifying bacteria has begun to slow down, we must immediately replace a part of the new water and supplement the nitrifying bacteria to ensure the normal operation of the nitrification system.

4. Albumins are all over the tank wall (round).

It is a small insect like a very short white filament doing rock climbing on the wall of the tank, then it proves that the fish water in this tank is very fat and old, and the nitrifying bacteria can't bear it. Because there are more bacteria and impurities in the fertile water, the fish are very susceptible to disease, and the fish disease will in turn act on the growth of nitrifying bacteria.

The nitrifying bacteria are all dead because the nitrifying bacteria consume oxygen. It is recommended that nitrifying bacteria be put once every 15 to 30 days, and nitrifying bacteria have aerobic characteristics, so sufficient dissolved oxygen should be ensured after nitrifying bacteria are put into the tank. Once the nitrification environment has been established, it is no longer necessary to inject nitrifying bacteria into the tank.

Nitrifying bacteria consume oxygen, and if the density of fish in the fish tank is too large, the oxygen supply is insufficient, which can easily lead to the death of fish. Nitrifying bacteria can be released once every 15 to 30 days, but for fish tanks that have been newly opened and have not yet established a nitrification system, they can be released once a week.

Nitrifying bacteria have aerobic characteristics, so after putting nitrifying bacteria into the tank, it is necessary to ensure sufficient dissolved oxygen, and the aeration pump can be turned on, but a large amount of water change should be avoided to avoid washing away the nitrifying bacteria.

Normally, it takes a month or two for a nitrification system to set up, so there is no need to inject nitrifying bacteria into the tank after the nitrification system is established.

Summary. Hello, the nitrifying bacteria are all dead because of too much input, which will lead to the death of the water without oxygen.

Why put nitrifying bacteria and the fish are dead.

Hello, the nitrifying bacteria are all dead because of too much input, which will lead to the death of the water without oxygen.

This kind of attention should be paid to control the measurement.

Pay attention to oxygen and change the water.

Fish are mostly cold-blooded, and a few are warm-blooded, breathing with gills and having jaws and fins. Extant fish can be divided into two main groups: cartilaginous fishes (such as sharks, etc.) and bony fishes (fishes with linear and wavy fins).

My fish pond has been added with active fish, and the fish have appeared one after another, how to get rid of the dead fish?

Increase oxygen. Will the fish die if the water is changed and oxygenated?

Not enough oxygen. The amount of active is too large.

Pay attention to the reduction.

Is it more than 200 grams of water to six cubic meters? Dead fish on the third day?

Too much. Plus 50-80 is enough.

To establish stable and efficient biochemical filtration, the filtration system must be turned on 24 hours a day, and studies have shown that nitrifying bacteria will die 2 hours after the water stops circulating.

The survival conditions of nitrifying bacteria are: the survival of nitrifying bacteria requires water and high oxygen, so they can only live in various microporous filter media such as biochemical cotton, biochemical balls, glass rings, ceramic rings, etc. They can only survive if they meet the needs of both water and oxygen.

Nitrifying bacteria are most suitable for living in weakly alkaline water, and grow and reproduce the fastest when the temperature reaches about 25 degrees.

Many people are reluctant to open 24 hours for the following reasons:

1. Fear of power consumption: There are many energy-saving filtration products now, even if it is a filter cartridge, generally speaking, it is a power of ten watts or tens of watts, and dozens of watts cannot consume much electricity in 24 hours, so there is no need to turn off the filter from an economic point of view. Fish farming itself is a form of amateur pastime that is content with a life of not worrying about life.

2. Fear of noise: The general filter sound will be a little loud, especially on the filter, especially in the dead of night, this sound will be more obvious, and it is indeed very annoying, so I don't want it to work at night, which is understandable.
