fish tank, the first thing to do is to reduce the feeding density of the fish tank and reduce the number of fish, so that the feces can be controlled. Usually, one liter of water can only raise one centimeter of fish, for novices, it is better to raise one centimeter of fish in two liters of water, so that the density of fish is safer.
in the daily feeding process, also need to feed the fish, feeding too much will lead to too much feces, so it is also very important to reduce feeding. Usually, fish can be fed three times a day, and each feeding should be finished within 3-5 minutes. It should be noted that the fish can not be fed for a long time, otherwise the fish will become an old man fish, and it will not grow up in the future.
can also reduce feces in water and improve water quality. Usually, the cycle of water change is not fixed, depending on the deterioration rate of the water body. If the fish tank is relatively small and the water quality is difficult to maintain, it is necessary to change it every three days or so. If the water quality is well maintained, it can be changed once a week, and each time the water change does not exceed one third of the total water volume.
If the filtration effect of the fish tank is good, there is no need to worry about more feces, they will be decomposed biologically, and ammonia nitrogen can also be converted. In order to strengthen the filtration, it is necessary to pay attention to the cultivation of bacteria when opening the jar, pour in the culture solution of nitrifying bacteria every week, and then turn off the lamp to explode oxygen for a period of time to promote its reproduction.
