生水指刚放出未经晾晒处理的自来水或井水。其水温常与鱼池中的水温相差较大,特别是自来水,含有的氯气较多,对金鱼的危害极大,轻者会出现中霉,引起歪头,脊柱弯曲、鳍的末梢充血等现象,重者会很快死亡。新水指自来水、井水、泉水经过晾晒静置沉淀2～3天后的水,与鱼池水温相似,此水养的金鱼体壮无病。陈水金鱼池中底部含粪便、污物的脏水,不利于金鱼生长发育,会导致金鱼缺氧死亡。老水鱼池中清洁而呈嫩绿色、绿色的水,其中以嫩绿色水为佳,老水中绿藻较多,是金鱼的辅助饵料。此水中腐败分解的有机物质少,溶氧较多,生话在这种嫩绿而清洁的老水中的鱼,食欲旺盛,鱼体健壮;色泽鲜艳,发育很快。还有一种池壁青苔丛生,池水日久澄清的水,也属于老水一类。这种水
Raw water refers to tap water or well water that has just been discharged without drying. The water temperature often varies greatly with the temperature of fish ponds, especially tap water, contains more chlorine, great harm to the goldfish, the light will appear in the mold, causing tilted head, spine bending, finial congestion and other phenomena, Heavy people will die soon. New water refers to tap water, well water, spring water after standing sedimentation 2 to 3 days after the water, and fish pond water temperature similar to the hydropic goldfish body strong and disease-free. Chen Shui gold fish pond in the bottom of manure, dirt, dirty water is not conducive to goldfish growth and development, will lead to death of goldfish hypoxia. Old water fish pond clean and was green, green water, of which green water is better, the old water more green algae, goldfish is the auxiliary bait. This decomposition of organic matter decomposition of water less, dissolved oxygen more, live in this verdant and clean water of old fish, strong appetite, robust fish; bright color, rapid development. There is also a wall of moss clusters, clear water as long as the pool, also belong to the class of old water. This water
