Causes of fish floating head
First, the convection of upper and lower aquifers leads to an anoxic and hot day, and the upper layer of water produces a lot of oxygen. Because of the hydrothermal resistance, the upper and lower aquifers are not easy to convective. If a thunderstorm or a gale is encountered, the temperature of the surface water drops sharply, and the upper layer of water flows down to the lower layer, carrying oxygen. The organic matter in the lower water is quickly consumed, and the upper layer of water-soluble oxygen is reduced and cannot be supplemented. Second, photosynthesis is weak, oxygen production is less than oxygen consumption in case of continuous rain or foggy weather, poor lighting conditions, phytoplankton photosynthesis intensity is weak, the amount of dissolved oxygen in the water supply is small, dissolved oxygen in water supply. Third, excessive water quality leads to increased oxygen consumption of organic matter and lack of oxygen. If you do not add new water for a long time, you can easily cause excessive water quality (water color turning black) or deterioration (all plankton death, water smelly) lead to lack of oxygen and lead from Fish floating head. 4. Zooplankton consume large amounts of oxygen and result in lack of oxygen. Due to the propagation of spring rotifers or Cladocera, large numbers of predatory phytoplankton make the water clear. At this time, the respiration of zooplankton is greatly increased, and the pool water is mainly dissolved in air. Supplementary oxygen, and dissolved oxygen can not meet the oxygen consumption to make the pool water lack of oxygen cause the fish floating head.
