Some fish farmers put filters on fish tanks and think it is unnecessary to change water. This view is wrong. Although filtration can maintain water quality for a long time, the function of the filtration system may be weakened or the installed filtration system may have poor performance. In this case, filtration only delays the deterioration of the water body, and the water body will eventually deteriorate.
Therefore, even if there is filtration, water should be changed regularly to prevent odor. In addition, the filtration system should be checked regularly, and the filtration material should be replaced in time after the filtration capacity drops rapidly.

Fish tank fish culture skills:
You can keep the fish half hungry every day, so that the digestion will be faster. Feed the fish once a day, don't feed too much at a time, and ensure that the fish are more active. Ensure that the feed is fresh, ensure that they are nutritionally balanced, and set a good time to feed. Do not change the time at will. You can choose a fixed place to feed every time.
Can't use raw water. Raw water is tap water that has not been dried. The water temperature in the fish tank is too different. You can choose to change the water once a week without changing it too often. When changing water, put it in the sun for a few days to keep the water temperature similar to that of a fish tank.
Tap water needs to be dried for several days, and the water temperature in the fish tank is the same. It is best to use old water to raise fish, because there are more green algae in old water, which is also a very good auxiliary feed for goldfish. If it is found that the color of old green water turns to clear water and there are a lot of green algae under the tank, it is necessary to replace this water in time. This kind of water makes fish sick easily. The water changed for fish must be stored for several days, and attention should be paid to how many fish to raise.
