Generally, it is not necessary to clean the dirty water pipes of the fish tank. As long as it does not cause blockage and affect the use, it is not necessary to care about it. Usually, the upper and lower pipes will be dirty, or because the power of the filter system is not enough, or the problem of the fish tank itself, resulting in some dirt can not be sucked away in time, thus accumulating in the corner, if not adjusted, it will not last long to wash clean.
1. Where to wash: The fish tank filter has many components. Not every part needs to be cleaned. Generally, only the filter cotton needs to be cleaned. You can check it at ordinary times, and if you find that the filter cotton is yellow, you can wash it. If the filter cotton is already very thin, it should be replaced directly with a new one.
2. What to wash: The filter cotton must be washed with the water from the original tank. If the water from an unknown source is used, it may cause the invasion of bacteria and pose a certain threat to the health of the fish. The raw water does not have to worry about this problem, and will not lose beneficial bacteria, and can prolong the cleaning cycle of filter cotton.
3. Precautions: Do not take out the whole filter and wash it again. In this way, the beneficial bacteria living on it, especially the nitrifying bacteria, will be eliminated, and the original nitrification system in the tank will be destroyed. In this way, it will do great harm to the fish, and even cause a large number of fish to die.
