bacterial house has no service life. It is made of glass or ceramics, so it will not be damaged under normal circumstances and can be used all the time. It should be noted that the bacterial house can not be easily replaced and cleaned, because it will lead to the death of a large number of nitrifying bacteria inside, thus destroying the ecological environment in the tank, and even killing the fish.
? 1. Blockage: There are two reasons for the blockage of the bacterial house. One is that the filter cotton is not effective, causing dirt to enter the filter box of the bacterial house to form blockage. The other is the blockage caused by the death of a large number of nitrifying bacteria. After blockage, the water flow can not pass through, which seriously affects the filtration, so it needs to be replaced. If you don't want to replace it, you must pay attention to cleaning at ordinary times, but don't wash it too frequently, and you can't wash it all at one time, you'd better wash it in batches.
2. Acid drop: The phenomenon of acid drop may occur during the use of the bacteria house. This is due to the excessive reproduction of nitrifying bacteria and the accumulation of a large amount of nitrate on it. Because it is very soluble in water, it will lead to the decrease of pH and the acidity of the water body. In this case, it is necessary to replace the bacterial house appropriately to prevent the situation from becoming more serious. Of course, replacing the bacteria house will cause the original ecological cycle to be broken, so it is necessary to re-establish the nitrification system before continuing to raise fish.
