In the process of fish farming, may encounter some problems, such as the fish tank suddenly does not filter the problem. It may be that there is a problem with the water supply and drainage system, you can check to see if they can work properly. There may also be a problem with the filter material, which will also lead to the fish tank not filtering. Specifically, there are many filter materials, including physical filtration and biological filtration, which need to be adjusted according to the specific situation.
After the fish tank is not filtered, you need to know the specific reasons first. As mentioned above, it is possible that there is a problem with the water supply and drainage system, so the first thing to check is this aspect. If there is a problem, you can repair this area first. If there is no problem with the water supply and drainage system, then there may be a problem with the filter material.
After the filter materials have been used for a long time, their functions will be affected to a certain extent, and they may even be unable to filter. In this case, it is better to replace the filter material. Specifically, the physical filter material has magic bag, magic carpet and so on, biological filter material has coral bone, bacterial house and so on, can try, the effect is good. In addition, we need to pay attention to the need to change the water while replacing the filter material. But replace half of it, do not let the water temperature change too dramatically. Considering that the water has just been changed half, some nitrifying bacteria can be added to the water.
