Question

Quizplus · Accepted Answer

The optimal pH range for most freshwater fishes and invertebrates is between 6 and 9. This range provides a stable environment for the organisms to carry out their metabolic processes and maintain physiological functions. pH values below 6 can be too acidic, causing harm to the animals, while values above 9 can be too alkaline and also cause physiological stress. Therefore, maintaining the pH level in the range of 6-9 is important for the health and survival of freshwater fishes and invertebrates.
