the fish excrement at the bottom of the big fish tank? The fish excrement at the bottom of the big fish tank is usually cleaned up when the water is changed. Prepare a pump, connect the pipe to the bottom of the tank, and pump out the water from the bottom, which will also bring out the feces in the process, thus completing the cleaning. It should be noted that the water should not be changed too frequently, so if the feces are produced quickly, other methods should be used to clean them up, such as raising some tool shrimps and snails, which can also eat the feces.
1, less feeding: want to reduce fish excrement, the most direct way is to reduce feeding. In the daily feeding process, the fish should be fed two to three times a day, and the fish should be fed within 3-5 minutes after each feeding. In addition, it should be noted that although fish have strong hunger tolerance, they can not be fed for a long time.
2. Raise less fish: In addition to controlling feeding, reducing the number of fish can also reduce fish excrement. Generally, the number of fish is related to the size of the fish tank and the size of the fish. One liter of water can raise one centimeter of fish. But for novices, it's better to keep one centimeter of fish in two liters of water, which is safer.
3. Add wave-making: If the fish tank has filtering equipment, but the filtering effect is limited, and there are always some feces scattered in the corner, you can install a wave-making pump, which can regularly generate water flow, so as to raise the feces in the corner, facilitate the filtration, and reduce the fish feces in the water.
