The choice of water quality is very important for fish culture in small fish tanks. Generally speaking, it is best to use tap water or chlorinated mineral water. If you choose tap water, pour the water into the fish tank and let it stand for a period of time, at least one day, to let the chlorine in the water evaporate.
It is not recommended to add some chemicals to the fish tank, because these chemicals are harmful to the health of fish. If you are very worried about water quality, you can choose a water filter to filter the water quality.
2, the choice of water temperature
For different kinds of fish, their requirements for water temperature are different. Generally speaking, fish can be divided into tropical fish and temperate fish. The suitable water temperature for tropical fish is between 24℃ and 30℃, and that for temperate fish is between 65438 06℃ and 24℃. Therefore, when choosing the water quality, we should choose the appropriate water temperature according to the types of fish.
If there is no equipment to control the temperature, the water temperature can be easily adjusted through conditions. When it is hot in summer, air conditioners or fans can be used to reduce the indoor temperature. In winter, heaters can be used to raise the water temperature.
Step 3 clean water
It is also important to keep the water clean for small fish tanks. It is recommended that you change the water in the water tank once every week or two to remove dirt and waste. If you use a water filter, you can keep the water clean for a longer time.
Fish manure and leftovers will be decomposed into excessive ammonia and nitrate, which will threaten the life of fish. So it is also important to clean the bottom regularly. A straw can be equipped to clean the dirt at the bottom more conveniently.
4. Oxygen content of water
Fish need to breathe oxygen. If the oxygen content in the water is insufficient, the fish will suffocate. So it is also very important to ensure the oxygen content in water. An air pump can be installed to increase the oxygen content in the cylinder. In addition, adding aquatic plants is also a very good way to keep the oxygen content in water.
