如何在春天给金鱼换水

金鱼（细节）

金鱼多久换一次水？“干水”在中国的北部和南部被广泛用于交换水来饲养金鱼。水交换方法通常基于部分交换。只有当水质极度恶化时，才能更换所有的新水。

养金鱼时，最禁止使用未经干燥的原水。突然向金鱼池中注入大量的生水，这很容易导致鱼油炸，甚至死亡。即使是干燥的熟水，也应根据季节、气候、环境温度、水清洁度、气味和含氧量的条件，根据需要和比例缓慢混合。不要猛倒或猛冲，以免伤到鱼。春季换水技术要点如下：

经过春季漫长的寒冷和阳光充足的冬季饲养，早春的金鱼身体虚弱。此时，它们开始迁移到户外环境进行繁殖。用水换鱼应该非常小心，一天一次，或者视情况每隔一天换一次。水的交换最好控制在总水量的10%左右。此时水温仍然较低，水中溶解氧较大，金鱼饲料仍然较少，鱼体耗氧率较低。少量交换干水可以满足金鱼的需求

早春和晚春，随着气温升高，金鱼的食物摄入量开始增加，活动也增加，鱼体的耗氧量也相应增加。因此，鱼群中的排泄物显著增加，每日交换水量逐渐增加。换水的最佳时间是下午4点以后。这时，金鱼已经吃饱了。换水时，将剩余的饲料和盆池中的所有污垢清除干净，然后加入适量的太阳水

换水方法是用纱布网将漂浮在金鱼盆和池塘水面上的污垢和泡沫清除干净，再用纱布网将金鱼盆和池中的水沿同一方向轻轻旋转3~5圈，以便将污垢集中在水中，然后用吸管将污垢吸出，并按照适当的比例将其粘在盆（池）的边缘，慢慢注入干燥的熟水

How to change water for goldfish in spring

Goldfish (details)

How often does goldfish change water? The "dried water" is widely used in the north and south of China to exchange water for raising goldfish. The water exchange method is generally based on partial exchange. Only when the water quality is extremely deteriorated, can all the new water be replaced

When raising goldfish, it is most forbidden to use raw water that has not been dried. A large amount of raw water is suddenly injected into the goldfish basin, which can easily cause the fish to fry and even die. Even the dried cooked water should be slowly mixed in according to the needs and proportions according to the conditions of season, climate, environmental temperature, water cleanliness, smell and oxygen content. Do not pour or rush violently to avoid hurting the fish. The key points of water exchange technology in spring are as follows:

After the long cold and sunny winter rearing in spring, the goldfish in early spring are weak. At this time, they begin to move to the outdoor outdoor environment for breeding. The exchange of water for fish should be very careful, once a day, or as appropriate, once every other day. The exchange of water is best controlled at about 10% of the total water volume. At this time, the water temperature is still low, the dissolved oxygen in the water is large, the goldfish feed is still small, and the oxygen consumption rate of the fish body is low. A small amount of exchange for drying water can meet the needs of goldfish

In the early spring and late spring, as the temperature rises, the goldfish's food intake begins to increase, the activity also increases, and the oxygen consumption of the fish body increases accordingly. Therefore, the excreta in the fish group increases significantly, and the daily exchange water volume increases gradually. The best time to change water is after 4pm. At this time, the goldfish are full. When changing water, remove the remaining feed and all the dirt in the basin and pool, and then add a proper amount of sun water

The water change method is to use gauze net to remove the dirt and foam floating on the water surface of the goldfish basin and pond, and then use gauze net to gently rotate the water in the goldfish basin and pond in the same direction for 3~5 circles, so as to concentrate the dirt in the water, and then use a suction pipe to suck out the dirt, and stick it to the edge of the basin (pond) according to the appropriate ratio, and slowly inject the dried cooked water
