the feces in the bottom sand of the fish tank? If you want to clean up the feces in the bottom sand of the fish tank, besides strengthening the filtering effect, you can also use a pipe to suck out the dirt at the bottom when changing the water. Regular cleaning can also work for a period of time. In addition, you can also raise some tool fish and shrimp, they will eat feces, but only short-term effective, after all, these organisms will also excrete, over time will also pollute the water quality.
1. Reduce density: The simplest way to reduce feces is to reduce feeding density. Because there are more fish, so the excrement will be more, as long as a few fish are reduced, the excrement will naturally be less. And keeping too many fish also increases the risk of friction, which can cause the fish's scales to be rubbed off.
2. Reduce feeding: In addition to more feces caused by more fish, more feeding is also a major reason. Although fish grow fast and eat too much, excessive feeding will also lead to the increase of residual bait and feces, which will pollute the water body and seriously affect the health of fish.
3. Wave-making: The function of wave-making is to strengthen the water flow, so as to raise the impurities at the bottom of the water, so that they can be sucked away by the water flow formed by filtration. In this way, the amount of feces in the tank can also be reduced. However, after being sucked into the filter tank, it will also have an impact on the water body, and subsequent decomposition and transformation are needed.
