CATDOLL : CATDOLL: Do I need to add oxygen to the fish tank in the yard?

1. Do I need to add oxygen when raising fish in the water tank in the yard?

Need not

Fish in aquariums generally do not need oxygen. This type of tank contains more water, but only a few fish, which are smaller in size. In addition, the water surface is in contact with the air, so there is rarely any lack of oxygen. In addition, this type of tank is deep, and the bottom pressure of oxygenation is high, so there may even be no bubbles. If you keep some aquatic plants in the tank, they can also produce oxygen through photosynthesis.

2. Why do fish jump around when raised with an oxygen pump?

Because fish are very sensitive. If they are frightened when oxygen is pumped, they will be fine after a while. Turning on the oxygen pump has many benefits for fish. The amount of dissolved oxygen in the water increases, the fish have a strong appetite, good vitality, and are not easy to get sick. It is also good for cultivating nitrifying bacteria, and the color of the fish is not easy to fade.

After injecting oxygen, let it rest. It's nothing. It will be fine after a few days of rest. It's best not to hang around it often except for feeding it.

3. How much water should be put in the oxygen pump when raising fish?

Raising fish in a fish tank is also a professional and technical job. The amount of water in a fish tank is also very particular. Generally speaking, the water in the fish tank cannot be completely filled, but the amount of water should be determined according to the size of the fish tank and the type of fish raised.

According to experience, for a small fish tank or a medium-sized round fish tank, water should generally fill two-thirds of the tank volume; for a long and large fish tank, water should generally fill four-fifths of the tank volume. Of course, if you are raising fish that live on the upper layer and like to jump, you should put less water to ensure the normal life of the fish. Or you can add a lid on the top of the fish tank to prevent the fish from jumping out of the tank.

When changing the water in the fish tank for the first time, you cannot change all of it, but should replace a quarter or a third of the old water each time to ensure that the fish can slowly adapt to the new water and allow them to live and grow normally.

4. Do I need to change the water when raising fish with oxygen rods in winter?

In winter, if the home is well heated, the fish tank is on a balcony with sufficient sunlight, the water temperature is above 20 degrees, the fish are in good condition, and the feed may be fed twice a day, morning and evening. If the filtration system is not strong, the water will soon become turbid and no longer transparent. There is also a situation where the water is transparent but feels sticky, similar to the stickiness of strong liquor, then it is also necessary to change the water in time to prevent the water from deteriorating, causing fish diseases and leading to death.

In this winter when the water temperature is high, if you feed more than twice, it is recommended to pump out one-fifth of the water from the bottom every evening or morning to ensure water quality.

5. Is it better to use aeration or micro-tube oxygenation for fish farming?

Compared with the current single oxygenation equipment, bottom oxygenation, that is, microporous aeration tube oxygenation, is the most ideal oxygenation method.

Energy saving, low consumption, high efficiency, first widely used in high-density farming, factory farming, large-scale outdoor farming, earth pond farming.

However, we need to consider the one-time investment, which is about 500 yuan per acre. Consider it carefully.

6. How to use the three-way pipe for fish farming and oxygenation?

A: In the process of raising ornamental fish, it is necessary to add a circulation filtration system and oxygen to the fish tank. Sometimes the system is often a main unit of an oxygen pump, which needs to be connected to 2~3 oxygen pump heads. At this time, a three-way hose is needed, mainly to connect the oxygen main unit. Through the three-way splitter, one tube is turned into two tubes, which is convenient for multiple oxygen pump heads to be used at the same time.

7. Why is there no need to add oxygen when raising fish in clay tanks?

Fish tanks generally do not require oxygen. This type of tank holds more water, but only a few small fish are kept there. In addition, the water surface is in contact with the air, so oxygen deficiency rarely occurs.

In addition, this kind of tank is relatively deep, and the bottom pressure of oxygenation is high, and it may even be possible that no bubbles will be produced. If you grow some aquatic plants in the water tank, they can also produce oxygen through photosynthesis.

8. What plants can be placed in fish tanks to increase oxygen?

Put pennywort.

The vitality of the pennywort is very strong. When planting it in the water of the fish tank, we can choose to soak the pennywort in water or just soak the roots in water according to the needs of our own fish tank. If the pennywort is completely soaked in water, then every time you change the water for the fish, you must carefully clean the roots and leaves of the pennywort to avoid the growth of green algae and bacteria on it, which will harm the pennywort and the fish.

9. Is there any other way to raise fish besides oxygen pumps?

When raising fish at home, there is usually a lack of oxygen in the water. The oxygen cannot meet the breathing needs of the fish, and the fish will float, that is, put their mouths on the water surface to get oxygen outside the water. The oxygenation pump can bring oxygen from the air into the water through the pipe. In addition, you can put oxygenators into the water, which can temporarily alleviate the problem, but it is not a long-term solution. The best method is to use a water pump to filter the water and increase oxygen, which can purify the water quality and increase oxygen.

10. What oxygen is used in fish farming?

Oxygen dissolving from the atmosphere: This is the most common source. Oxygen in the air will slowly dissolve into the water under atmospheric pressure, thereby increasing the amount of dissolved oxygen in the water. However, the amount of oxygen dissolved in the water will change with changes in weather and air pressure. This is why the oxygen content in the water is high on sunny days and low when it is hot and humid (low air pressure).

Photosynthesis of plants: This is also an important way, especially in outdoor water bodies with sufficient sunlight and rich phytoplankton. The amount of oxygen obtained can be greater. When the weather is good, the dissolved oxygen in the surface of the water can even reach saturation. However, when fish are raised indoors or filtered water is used to raise fish, the amount of oxygen obtained will be less because there are fewer algae in the water or the light is not strong.

Artificial oxygenation: There are many ways to artificially increase oxygen, but the most commonly used method in ornamental fish farming is to use an air pump (oxygen pump) to increase oxygen. The principle is to use a compressor to press air into the water body, so that the oxygen in the air dissolves into the water to increase oxygen. Elsewhere, when filtering, the water in the fish tank is pumped up and fully exposed to the air to increase the dissolved oxygen in the water body, such as the trickle flow and waterfall flow filtration methods we often use. In addition, there are also chemical drugs such as oxygenators to increase the dissolved oxygen in the water body, but this is only an emergency method.
