Can ? Water can't be stored in a bucket for a month to raise fish. Although the trapped water needs to be dried, but the time can not be too long, because drying for a long time will also allow some bacteria to breed in the water, so that the water will be polluted, used to raise fish will also be harmful to the health of fish. Under normal circumstances, drying water can not exceed a week, according to the need to prepare a few days in advance, so that it will not affect the change of water.
for the water for fish farming? 1. Water quality: The water for fish farming must pay attention to the water quality, which has a great impact on the health of fish. In order to maintain water quality, water needs to be changed regularly. In addition, it should be noted that different fish have different requirements for acidity and alkalinity, some like weak acidic water, some like weak alkaline water, but also pay attention to control.
2. Water temperature: If you raise eurythermic fish, the water temperature requirement is often a little smaller, because this kind of fish has strong adaptability, but tropical fish is not good, you must keep the temperature above 20 ℃, if the temperature is low, the survival of the fish will be seriously threatened.
3. Dissolved oxygen: In order to allow the fish to breathe normally, the level of dissolved oxygen in the water is also critical. In order to increase the oxygen content, an oxygen pump can be used to pump oxygen into the water. In this way, the oxygen in the water is more sufficient, and the fish's breathing is guaranteed.
