the water quality of the fish tank? If you want to test the water quality of the fish tank, you can use special equipment or test paper. According to the different directions of the test, you can choose different methods. If it is to detect water temperature and dissolved oxygen, a dissolved oxygen meter can be used. If it is to detect transparency, it can be observed directly with the naked eye. If it is to test the acidity and alkalinity, it needs to be tested with PH test paper. If the hardness of water is to be tested, a hardness reagent is needed.
of fish tanks 1. Strengthen filtration: In order to improve the water quality in fish tanks, the first thing to do is to strengthen filtration. In addition to replacing the filter with higher power, the filter material used for a long time can also be cleaned. Usually, only the filter cotton is washed, and it must be washed with raw water. The new water will affect other filter materials.
2. Change water regularly: Changing water is the fastest way to improve water quality, but it should not be used frequently, because it will have a certain impact on fish. Usually it can be changed once a week, and the water quality can be maintained well. It can also be changed once every two weeks, about a quarter of each time. It is better to keep the same temperature before and after changing the water.
3. Reduce feeding: In addition to improving water quality, we can also prevent the deterioration of water quality by some means, the most important of which is to reduce feeding. Fish can not be fed too much, otherwise it will not only pollute the water body, but also cause the fish to suffer from enteritis, which can be fed in a small number of times.
