The best way to clean fish feces in a fish tank is to install a pump in the tank and let it pump the fish feces away. First of all, we should choose the right type of pump, too large is easy to overflow, too small is limited water flow. Secondly, the suction port should be shortened a little, so as to increase the suction. It should be noted that if the fish excrement will flow to the corner of the fish tank, it is necessary to open the oxygen port next to the pump, and seal the flow-making oxygen nozzle, so that the water flow from the small nozzle can wash the fish to the suction port.
1. Reduce feeding: The main reason why there is a lot of fish feces is that there is too much feed. Fish are usually relatively resistant to hunger. Feeding too much can easily damage the intestines and stomach, causing it to get sick. In addition, residual bait and fish feces can also affect the water quality. Therefore, starting from the source, we need to reduce the usual feeding, which can be fed once a few days, each time to seven or eight points full.
2. Change the water regularly: If there is no bottom sand in the fish tank, you can clean up the fish feces when changing the water. As long as the water is pumped out from the bottom of the tank, the fish feces and residual bait can be cleaned up, and then new water can be slowly added from the wall of the tank. However, when changing the water, be careful not to pull the fish out of the tank.
3. Fish culture cleaning: In addition to these methods, fish culture can also be used to clean up. Usually choose the benthic scavenger, this kind of fish can eat the bottom of the residual bait and fish, but it should be noted that because of mixed culture, so the size of the fish should be close, otherwise too small fish will be eaten by it.
