When the tank was opened, there were no nitrifying bacteria, and now I have been raising Arowana for

The golden dragon is also very leathery, and it is said to be the same as the map.

It should be fine. Just filter you on.

For a newly opened aquarium, do not use nitrifying bacteria on day 1, because the water will not produce enough nitrogen, amines, etc. on day 1. Nitrifying bacteria are a class of aerobic bacteria, including nitrite bacteria and nitric acid bacteria, that generally live in aerobic water or sand layers. Nitrifying bacteria are widely found in the natural environment, they need water and oxygen to survive, they are suitable for survival in weakly alkaline water, and they will grow and multiply rapidly when the temperature reaches about 25°C.

1. Can nitrifying bacteria be put on the first day of opening the tank?

1. Do not use nitrifying bacteria on the first day of a newly opened aquarium, because the water will not only not produce enough nitrogen, amines and other substances on the first day, but also the residual chlorine in the water will inhibit the implantation and growth of nitrifying bacteria. On the first day of opening the tank, an appropriate amount of photosynthetic bacteria can be added to the aquarium water body, which can decompose harmful substances.

2. Nitrifying bacteria are a kind of aerobic bacteria, mainly including nitrite bacteria and nitric acid bacteria. Nitrifying bacteria mainly live in aerobic water or sand layers, and play an important role in the process of nitrogen cycle water purification. Nitrifying bacteria do not need to be purchased specifically, and after the oxygen content and organic matter in the fish tank reach normal levels, a stable colony can be established in about 2 months.

3. Nitrifying bacteria exist in the natural environment, and their survival requires water and oxygen. Nitrifying bacteria can multiply in a large number of microporous filter media such as soil, sand, biochemical cotton, biochemical balls, glasses, ceramic rings, etc., and nitrifying bacteria are suitable for living in weak alkaline water, and will grow and reproduce the fastest when the temperature reaches about 25 °C.

Second, how long can the fish be released after the tank is opened

1. The new fish tank generally needs to be raised in water for 5-6 days before the fish can be released. Be sterilized and disinfected before raising water, and then fill the fish tank with water to dry for 2-3 days, because most of the water has chlorine, drying can eliminate chlorine. Oxygenate the water body for another 1-2 days, establish a nitrification system, put in an appropriate amount of nitrifying bacteria potion, and wait until the water is clear before releasing the fish.

2. After the new tank is bought, it is generally disinfected and cleaned, and water can be injected into it. Tap water can be used for water injection, which is more convenient to obtain, and tap water will not have other pollutants except for residual chlorine, and fish farming is also relatively safe. After the water is filled, it needs to be dried for a few days, this process is called trapped water, which mainly allows the chlorine in the water to volatilize, and can also be injected directly into the trapped water.

3. After water injection, it is necessary to cultivate bacteria, which is nitrifying bacteria. Because the organic matter in the water body, such as residual feed and fish feces, will be decomposed by microorganisms to produce ammonia nitrogen, which is not good for the health of fish, so it needs to be treated with nitrifying bacteria. The way of cultivating bacteria is relatively simple, pour nitrifying bacteria into the fish tank and add a little fish food, and then turn off the light to burst the oxygen, and wait until the water quality is clear, which means that the culture is completed.

Fish tank nitrifying bacteria can generally be added once in about 15 30 days, and if it is in the initial stage, it can be added once in about 7 days. Nitrifying bacteria are suitable for use in environments with high ammonia concentrations, which is helpful for fish growth.

Nitrifying bacteria are the treatment agents that can control the pool water, and the ammonia removal effect is strong. If there are fish and other small aquatic animals at home, during the maintenance period, it is generally about 15 to 30 days to add nitrifying bacteria to the fish tank.

During the maintenance period, it should be noted that before the nitrification reaction system is established for the fish tank, nitrifying bacteria can be added to the water once in about 7 days. After the nitrification reaction system is formed in the later stage, it can be added once in about 15 days.

After the nitrification system is set up in the fish tank, the ammonia in the fish tank can be converted. Nitrifying bacteria do not affect water quality and can also avoid excessive ammonia concentrations, which is good for the growth of animals such as fish.

After the fish enter the tank about 1 week later, you can put in nitrifying bacteria, under normal circumstances, when the new tank is opened, the raised water will be injected first, and the filter should be opened.

At this time, the water in the tank will become turbid at first, and it will become clear after 2-3 days. Once the water in the tank is clear, you can put in the fish that have broken into the tank.

After putting in the fish that broke into the tank, you can put nitrifying bacteria. Because the main role of nitrifying bacteria is to decompose ammonia and nitrogen in fish feces and keep the ecosystem in the fish tank stable.

Under normal circumstances, fish tanks that have been cultivated for a long time will build nitrifying bacteria on their own. However, after the new tank is opened, the nitrifying bacteria are produced at a slower rate, and the keeper needs to join regularly to help establish the ecosystem. If it is a new tank, you can add nitrifying bacteria once a week.

Once the nitrification system is established, it can be added once every 15-30 days. Nitrifying bacteria are beneficial bacteria that convert harmful substances such as ammonia and nitrogen from organic matter in fish tanks into nitrates.

The nitrifying bacteria need to be put in the tank first, and only after the nitrification system is formed, the ecosystem in the fish tank can be perfected.

After putting in the nitrifying bacteria, you can put in the fish.

Toxic substances such as ammonia nitrogen in the fish tank are just food for nitrifying bacteria, and the nitrosifying bacteria in the nitrifying bacteria will decompose these substances into nitrite, and finally be directly absorbed by nitrifying bacteria.

When putting nitrifying bacteria, it is best to avoid the white turbidity period when the tank is opened, and wait for the water in the fish tank to become clear before putting it.

1. Disinfection: The fish tank needs to be disinfected first, and the fish tank can be soaked with potassium permanganate and chlorine dioxide, which can be soaked for 2-3 hours.

2. Water raising: The tap water used at home contains more chlorine, and the breeder needs to put the tap water in the sun for 2-3 days, which can effectively eliminate chlorine and harmful substances in the water. After injecting the raised water and nitrifying bacteria into the fish tank, you can try to put in the fish.

3. Put the fish into the tank: the keeper can choose some more solid fish to break into the tank, as long as the fish can survive for a few days, it means that the tank is successful.

Under normal circumstances, the bacteria are digested after waiting for the fish to enter the tank for 3 days, that is, the new tank is added after 1 week of water. The new fish tank is generally set up, put water on it, and open the filter (the filtration is generally 24 hours a day). After 2 or 3 days of clearing, put a few small fish with strong vitality such as zebras to "create a tank", the purpose of which is to make the food needed for nitrifying bacteria.

At this time, some people began to nitrify bacteria, and the saying is that the best finished nitrifying bacteria on the market are generally bacterial spores, and it takes about 3 days to release dormancy. After 3 days, fish feces can be decomposed into a large amount of food for nitrifying bacteria, and at this time, it is necessary to add a large amount of food for each bacteria that have been released from dormancy, which is conducive to their growth.

It has been disinfected with potassium permanganate - easy to remain, next time with 75% medical alcohol, simply wipe.

When can I add nitrifying bacteria --- fresh water 3 days later.

When can I add nitrifying bacteria--- if it has been trapped in water for 3 days, you can put in the nitrifying bacteria culture medium.

Put a couple of fish in the tank, and then grow nitrifying bacteria.

Do you need to add nitrifying bacteria to Arowana? Therefore, the use of nitrifying bacteria depends on the water quality in your fish tank, and the new water body does not need to add nitrifying bacteria. Most of the nitrifying bacteria on the market are very weak and require a long time to resurrect the bacteria, so it takes at least a week or so for the nitrifying bacteria to play a role in the water body; In aquaculture, chemical agents are generally used for ammonia nitrogen treatment in water.

To sum up, nitrifying bacteria can now be added to the fish tank in small amounts, do not add too much, causing turbidity in the water, as long as the circulating water has been flowing, the ammonia nitrogen and nitrite content of the water will basically not exceed the standard. Nitrifying bacteria is only an adjunct, and it is recommended to strengthen the monitoring of water quality (dissolved oxygen, pH, ammonia nitrogen, nitrite, etc.).
