The temperature changes from 28℃ to 36℃ a day, so what is the temperature change range of outdoor fish ponds?

Outdoor temperature is related to many factors, such as light and water algae, pond bottom, wind, water depth and so on. Some fish ponds in different ponds are hot, the upper water is 36 degrees Celsius, and the bottom may only be 5- 10 degrees Celsius. The surface water temperature will not change more than 5 degrees Celsius, because if the overall temperature of the fish pond changes more than 3-5 degrees Celsius, a large number of fish will die. If the thermometer shows 28-36 degrees Celsius during the day, the water temperature in the fish pond will be lower than the thermometer, while the water temperature in winter will be higher than the air temperature, which means the specific heat capacity of water and air. There are too many factors, only remember about 2 degrees.
