1. How much water is suitable for fish tank culture Four fifths of the total capacity of fish tank culture is enough. The reason why it should not be filled is that if there is too much water, the pressure at the bottom will be too large, which will lead to uneven stress from top to bottom, thus improving the possibility of cylinder explosion. However, it is worth mentioning that not all fish tanks can hold four fifths of the water, and fish tanks with large volume and thick glass can, but fish tanks with small volume and thin glass can not, and can only hold two thirds of the water.
2. What are the water requirements for fish farming1. Water temperature: The water for fish farming should pay attention to the temperature first. If it is a wide-temperature fish, it is easy to say that it has a wide range of adaptation to temperature and can be raised without special heating. However, if it is tropical fish, it is necessary to control the water temperature and keep it above 20 ℃. Low temperature will affect the health of fish.
2. Water quality: Besides water temperature, water quality is also very important. If the water quality is not good, fish will also be affected. Usually, if you want to maintain water quality, you should pay attention to filtration besides changing water regularly. Filtration is generally divided into three parts: physical filtration, chemical filtration and biological filtration, and it is best to include all of them in the fish tank.
3. Dissolved oxygen: Dissolved oxygen in water is also a key factor. If the oxygen content is relatively low, the breathing of fish will become a problem, which is very unfavorable to their health. Usually, if you want to improve dissolved oxygen, the best way is to use an oxygen pump to oxygenate, and it is best to keep the oxygen pump open all the time, so as to keep dissolved oxygen.
