regularly to make the water in the fish tank clear and transparent, the first thing to do is to change the water regularly. Usually, the cycle of changing water and the maintenance of water quality are generally maintained well in filtered fish tanks, so it can be changed once every two weeks or so. If the maintenance is poor, it should be changed once a week, and the water change is about one quarter or one fifth each time.
, in addition to changing water, the usual way to maintain water quality is filtration. Good filtration can not only maintain the condition of the water body, but also restore the clarity of the muddy water. Filtration is generally divided into physical filtration, chemical filtration and biological filtration, in order to make the filtration effect good, these three kinds of filter materials need to be prepared.
control In the daily feeding process, feeding food will also make the water turbid, so it is necessary to control the amount of feeding to maintain the water quality. Because fish digest quickly, they can eat more, but it is harmful to their health, and may even suffer from enteritis, so usually after each feeding, it is necessary to ensure that the fish finish eating in about 3 minutes.
of fish. If the density of fish is too high, the fish tank itself will be small and the number of fish will be large, which will accelerate the deterioration of water quality. So we need to pay attention to the feeding density, usually one liter of water can raise one centimeter of fish, novice, it is best to raise one centimeter of fish in two liters of water, so as to better maintain water quality.
