The gap of the ceramsite itself is relatively large, and the fish feces can easily fall into it. If the nitrification system in the tank is good, you can also completely ignore it, as long as the filtration is good enough, and the water is changed in time at ordinary times. If you are worried about polluting the water, you can wash it with a sand washer, or simply change it into fine sand.
1. Change the water to clean up: The feces in the fish tank will pollute the water quality, and will produce ammonia nitrogen after being decomposed, which is harmful to the health of the fish, so it needs to be cleaned up in time when changing the water. Usually need to change the water once a week, each time need to change a third or a quarter, change the water can use siphon method, the water from the bottom suction, so that the dirt will also follow the discharge, and then from the top slowly into the new water.
2. Strengthen filtration: In addition to cleaning the feces in the fish tank by changing the water, it can also be pumped away by filtration. As long as the suction port of the filter is properly moved down, the dirt in the cylinder will be filtered out slowly, but the filter screen should be replaced regularly to avoid too much dirt causing blockage and affecting normal use.
3. Ecological filtration: In fact, the feces in the fish tank itself will be decomposed by microorganisms, but the decomposition will produce ammonia nitrogen, which is harmful to the fish. Therefore, nitrifying bacteria are needed to convert ammonia nitrogen into nitrate. Therefore, as long as a good nitrification system is established, even if the feces in the tank are not taken care of, there will not be too big a problem. To build a digestive system, you need to pour nitrifying bacteria into it, then turn off the light and explode oxygen for a period of time.
