the excrement in the fish tank 1. Change the water to clean up: The excrement in the fish tank is usually cleaned up when the water is changed. To change the water, you need to pump out the old water first. You can use a pump or find a pipe to siphon the water from the bottom of the tank. In this process, you can clean up the feces at the bottom, and then inject new water.
2. Filtration and cleaning: If you feel that it is too troublesome to change the water and clean it, or there is sand at the bottom of the tank, which is not convenient to clean it out by pumping water, you can use the filtration method to clean it. Biofiltration breaks down feces and converts ammonia nitrogen into nitrates, thus preventing fish from being poisoned.
3. Biological cleaning: Biological cleaning is also a commonly used method. You can raise some black-shell shrimps, tool snails, etc. They will eat the feces at the bottom of the tank. However, polyculture also has certain risks. It is necessary to avoid the explosion of these organisms, so as not to affect the survival of fish. There are generally two reasons
fish tank feces. The first is that there are too many fish and the feeding density is relatively high. In view of this situation, the best way is to raise a few less fish. You can divide some fish into other tanks or change to a larger tank. The second reason is to feed too much food, so we should control the amount of feeding at ordinary times to ensure that the fish can eat within 3-5 minutes each time.
