1 meters 2 fish tank fish excrement is very simple, just need to prepare a pipe, and then use siphon method to discharge it when changing water. It should be noted that as long as there is not too much fish excrement, there is no need to clean it up specially. Microorganisms in the tank can decompose it, and the ammonia nitrogen produced can also promote the establishment of nitrification system. But if the amount of fish excrement is too large, we should be vigilant, which may lead to the destruction of the circulation in the cylinder.
1, the density is too big: the reason why fish excrement is more, because the feeding density is too big, the fish excrement will be more. Usually, one liter of water can raise one centimeter of fish. Calculate the upper limit of fish farming according to this ratio, and then control it within this range.
2. Feeding too much: In addition to the large number of fish, too much feeding at ordinary times can also lead to an increase in fish excrement. In the daily feeding process, it can be fed two to three times a day. Each feeding should ensure that the fish are eaten up in a short time, and try not to leave residual bait, which is as harmful to water quality as feces.
3. Filtration is too weak: If the filtration effect of the fish tank is not strong enough, there will be more fish excrement, which can be absorbed and decomposed after filtration. At the same time, there are special nitrifying bacteria for further transformation. In order to strengthen the filtration, attention should be paid to the cultivation of nitrifying bacteria and the establishment of nitrification system.
