with the large temperature difference when the koi carp changes water? When the koi carp changes water, the temperature difference should be eliminated in time. If the new water has not been poured into the fish tank at this time, it is better to pour hot water into the new water in order to keep the temperature of the new water consistent with the water temperature in the fish tank, so as not to stimulate the koi. If new water has been poured into the fish tank, you need to use the heating rod immediately to heat the water.
