1、水质好坏的判断(1)pH值。pH值反映池水的酸碱度,是水质的重要指标,直接影响着水体中的化学过程和生物过程。鱼类的安全pH值范围是6～9,最适生长的pH值为7～8.5。(2)透明度。池水透明度的大小,可以大致反映池水中饵料生物的多少,即水的肥瘦。一般透明度在30厘米左
1, to determine the quality of water (1) pH value. pH value reflects the water pH, is an important indicator of water quality, directly affects the chemical and biological processes in water. Fish safety pH value range is 6 ~ 9, the optimum growth pH is 7 ~ 8.5. (2) transparency. The size of the transparency of the water can roughly reflect the amount of food organisms in the water, that is, fat and thin water. General transparency at 30 cm left
