If you want to make the fish in the basin without oxygen deficiency, you need to use an oxygen pump to give it oxygen. Oxygen pump is actually a motor, the power generated in the process of operation will air into the fish tank, all do not have a special oxygen pump, can inflate the motor can be used. In addition, if the pot is deep enough, you can plant some aquatic plants, which can also provide the right amount of oxygen.
1. Equipment oxygenation: The most commonly used oxygenation is the oxygen pump. Of course, the filtration system of some fish tanks can also bring air into the water, thus achieving the effect of oxygenation. Generally, the oxygen pump does not need to be opened from day to night, 2-4 hours a day is enough, if the breeding density is large, the time can be extended appropriately.
2. Drug oxygenation: Drug oxygenation is a relatively emergency method, which is mainly used in large-scale fish farming, and oxygenation agents are usually used. When the fish are found to have floating head performance, indicating that the water anoxia is more serious, this time can be put in, but also pay attention to control the dosage, in order to avoid the formation of phytotoxicity.
3. Plant oxygenation: As the name implies, plant oxygenation relies on plants to release oxygen during photosynthesis, thereby increasing the dissolved oxygen in the water body. Generally, some aquatic plants can be planted in the fish tank to improve the oxygen content, but at night it will still consume oxygen, so it needs other ways to supplement.
