WebAs fish respire they produce carbon dioxide as a byproduct. Carbon dioxide reacts with water to form a weak acid. This weak acid will in turn decrease the pH of the water. High levels of carbon dioxide (greater than 20 ppm) will interfere with the oxygen uptake in the fish's blood. High levels of carbon dioxide sometimes are found in well water. WebCarbon dioxide levels can be increased by adding organic matter such as cracked corn, soybean meal or cottonseed meal to ponds. As organic matter decays, it releases carbon dioxide. This method does not reduce pH immediately, but it is a safe and relatively dependable practice that yields results rather quickly. ... fish will be killed when ...
