How much do the PH value and carbon dioxide in water affect your koi according to the difference of koi breeds?
(1) Effect of pH value: pH value of test water can be judged by pH test paper or koi activity.
For example, when the water is acidic, the koi's respiration is reduced, the activity is slowed down, the appetite is poor, and the growth is stopped; and too much alkalinity will affect its growth and death.
(2) The influence of carbon dioxide: the content of carbon dioxide has obvious diurnal variation. The high content of carbon dioxide in water will reduce the binding ability of hemoglobin and oxygen in koi carp.
In this case, even if the dissolved oxygen content in the water is not low, Koi carp will have difficulty breathing.
