How to achieve a balance of oxygen in the negative pressure fish tank

There is no negative pressure fish tank, the so-called negative pressure is that the air pressure in the tank is lower than the air pressure outside the tank, so this is to make the fish tank seal and extract some air, but such a fish tank is unable to raise fish, and the fish will die quickly due to extreme lack of oxygen.

The negative pressure you said should refer to the negative pressure intake pipe on the three-in-one pump, if this, there is no balance problem, according to the type of fish you raise, some do not need to add oxygen, some need to add sufficient oxygen, to control the size of the air intake, there is an air intake valve on the market can buy one to use, or do not spend money, the air intake pipe is folded back to the degree of folding to control the size of the air intake.

The principle of negative pressure is used to raise the water level and increase the ornamental surface, because it is easy to operate under the opening, and the shortcomings of the traditional fish tank can only be long and not high, so that it can stand majestically.

In fact, there is no negative pressure fish tank, the so-called negative pressure is that the air pressure in the tank is lower than the air pressure outside the tank, so this is to make the fish tank seal and pump out some air, but such a fish tank is unable to raise fish, and the fish will die quickly due to extreme lack of oxygen.

If you need to rely on oxygen, press the water down. There will be two problems: 1. The fish tank bursts due to high negative pressure; 2. All the fish and grass were wiped out due to high negative pressure.

At present, negative pressure fish tanks are specially made by professionals, mainly for the tips and experience of pressure regulation technology.

Hope it helps.

Have fun!

If the fish tank is larger, you don't need to be oxygenated all the time, because the oxygen in the large fish tank will not be consumed in a short time. If the fish tank is always filled with live water and the fish tank has a good filtration system, there is no need for proofing at all, because the live water will continue to carry oxygen into the fish tank.

If the fish tank is relatively large, you don't need to keep oxygen, because there is more water in the large fish tank, and the oxygen content in the water will be more, even if the oxygen is stopped, the oxygen in the water will not be consumed in a short time.

In addition, if there is always live water injected into the fish tank and it is well filtered, there is no need for oxygen at all, because the injected live water will carry oxygen into the fish tank, and the water in the fish tank will not be hypoxic.

It should be noted that in case of high temperature and rainy days, the air pressure is low, and the oxygen content in the water is also very low.

The fish tank oxygen dispenser does not need to be turned on all the time.

The oxygen pump does not need to be left on all the time, it only needs to be turned on for about two hours in the morning and in the afternoon. If the temperature is high or the weather is rainy, you will need to extend the time a little. At the same time, if there are aquatic plants at the bottom of the water, it will need to be left open for another hour in the evening.

Although the oxygen pump is always on is not harmful to the fish, the fish that have adapted to the nitrox environment are prone to some discomfort and even death if the oxygen is reduced due to power outages and other reasons. Usually a few hours a day is fine, as long as the breathing of the fish in the water is satisfied, no more oxygen is needed.

When does the oxygen pump in a fish tank turn on?

1. Daily: If there are not many fish raised, there is no need to turn on the oxygen pump, but for some large fish, it is still necessary to open for 2-4 hours a day, if it is in summer, the weather is hot or it has been raining, and the dissolved oxygen in the water body is reduced, it is necessary to open it for 2 hours more. In addition, if you want to raise aquatic plants, you need to open them for 1 hour in the evening.

2. Open the tank: fish farming needs to open the tank, and the tank needs to be cultivated, many beneficial bacteria belong to aerobic bacteria, such as nitrifying bacteria, which must be multiplied in large numbers in an environment with sufficient oxygen, so at this time it needs to be oxygenated all the time, and it will take about a day to complete the cultivation.

3. Treatment: If the fish are sick, the content of microorganisms in the water will often increase, so it will lead to insufficient oxygen in the water, and at the same time, the tablets put in the first period will also consume oxygen, so during the treatment of the fish, it is necessary to use an oxygen pump to oxygenate it.

Fish in tanks generally do not require oxygen. This tank holds a lot of water, and there are very few fish raised, and they are all slightly smaller fish, and the water surface is in contact with the air, so there is rarely a lack of oxygen. In addition, this kind of cylinder is relatively deep, and the bottom pressure of oxygen injection is high, and there may even be no bubbles.

If you keep some aquatic plants in the tank.

words, through photosynthesis.

It can also produce oxygen.

1. Maintain water quality: The oxygen content in the water is high, which has a certain role in maintaining water quality. It is mainly divided into two aspects, on the one hand, oxygen promotes nitrification bacteria.

growth and reproduction, so as to better convert ammonia nitrogen.

On the other hand, it inhibits anaerobic bacteria.

to prevent the deterioration of the water body.

2. Conducive to breathing: the main purpose of oxygen is to make the fish breathe better, although this animal lives in the water, but also needs to take in the oxygen in the water, in order to maintain the dissolved oxygen in the water, you need to inject oxygen into the water. Of course, a certain amount of oxygen can also be added by means of water change and filtration.

3. Accelerate growth: The higher the oxygen content in the water, the more energetic the fish will be, which will also promote their growth and accelerate digestion. Of course, there are many conditions required for growth, in addition to sufficient dissolved oxygen, water temperature and abundance of feed.

It is still very simple to install an oxygen infusion machine in a fish tank.

First of all, the sponge should be put in it, then the leaking parts should be installed, be sure to tighten it, and at the same time, the stuck parts should be placed in the card slot, and then the filtration equipment should be installed, and the water pipe should be connected.

Finally, turn on the power and the oxygen machine can work on its own.

If there are no bubbles, you need to check its location, or whether the outlet pipe is blocked, etc.

2. What are the benefits of oxygen 1. Improve dissolved oxygen: The most direct benefit of oxygen is to improve the dissolved oxygen of the water body, the oxygen content in the water is high, and the fish will breathe more smoothly.

If there is a lack of oxygen, it will cause it to float, and in serious cases, it will cause it to turn over and even die, so it is still necessary to take oxygen at all times.

2. Improve water quality: the oxygen content of the water body rises, which is also conducive to the establishment of the nitrification system, and the nitrifying bacteria have a very positive effect on the water quality of the fish tank, which can convert ammonia nitrogen into nitrate, so as to avoid fish poisoning, and nitrate itself is one part of the lead of the aquatic plant.

3. Aeration and dechlorination: By adding oxygen to the water, it can have the effect of aeration and dechlorination.

Generally, the water used for fish farming is tap water, although the tap water looks clear, but there will be residual chlorine residue during the disinfection process, which is not good for the health of the fish, and by aeration of oxytung tung, the volatilization of chlorine can be accelerated.

The fish tank does not need to be oxygenated all the time.

If the density of the fish tank is large, it must be oxygenated all the time, if the density is small, it does not need to be oxygenated 24 hours a day, and it can be fixed and oxygenated several times a day.

The effect of oxygenation can increase the density of oxygen in the water, so that the oxygen in the water is evenly matched, which is conducive to the survival of fish and aquatic plants in the fish tank. It can produce a stable flow in the water, which is conducive to the growth of fish.

If oxygen is not required:

It is best not to raise goldfish with additional oxygen, especially the high-power aeration pump, not to mention the kind that will also make flow. Although goldfish are high oxygen consumption aquarium fish.

However, they are also not suitable for too much water flow, if the aeration pump will stir up too much water, the goldfish need to maintain balance in the water, the body will inevitably tilt, and over time the body's swimming posture may change, if it is serious, it may also lead to loss of sight.

The fish tank is too small and don't oxygen, some fish tanks are only 20 cm in length, and the water body is small, plus the water flow stirred up by the aeration pump, the water in the whole fish tank is basically in turmoil, and the fish in it can't stand it, after all, they also need to rest.

In particular, some small tropical fish, the most common guppies, if the current is constantly turbulent and very large, then it is likely that the fish will die of exhaustion.

These two situations are more common when you don't oxygenate the fish tank, in fact, there are still many aquarists who have experienced them, and I hope you can correct them in time if you have these two situations.

It is no problem for the fish tank to be oxygenated all the time, but once the oxygen is cut off, it is easy to cause the fish to have a stress response and even die directly. If the oxygen consumption of the fish is relatively high, it is generally enough to inject oxygen for 2-4 hours a day, and it can be extended by 2 hours on rainy days. In addition, when the tank is opened, oxygen needs to be burst into the tank.

If the fish is sick, a proper oxygen explosion will help it recover.

On the one hand, sufficient oxygen can indeed make the fish breathe more smoothly, there will be no hypoxia, and it also helps the reproduction of some aerobic bacteria, while maintaining water quality. On the other hand, fish that have been living in a high dissolved oxygen environment for a long time will immediately develop a stress response and even die if they are released into a water body with slightly low dissolved oxygen.

1. Daily oxygenation: If the number of fish is large, the breeding density is relatively high, or they are all large fish, the demand for oxygen is high, which requires oxygen at ordinary times. However, it is enough to control the time of oxygen injection in 2-4 hours every day, and you can take oxygen for 4-6 hours in summer and rainy weather, and if there are aquatic plants, you need to inject oxygen for 1 hour in the evening.

2. Cultivation and oxygenation: The fish tank needs to be cultivated when the tank is opened, and the bacteria here are nitrifying bacteria, which is an aerobic bacterium, and oxygenation helps it grow and reproduce. Therefore, after pouring nitrifying bacteria, it is often necessary to continue to inject oxygen for 24-48 hours, so as to better establish the nitrification system.

3. Oxygen during illness: If the fish is sick, it also needs to be properly oxygenated, and sufficient oxygen is very helpful for its recovery. Moreover, after some drugs are put into water, they will affect the content of oxygen, and oxygen can also have the effect of supplementing dissolved oxygen.
