Water Quality
Enrolment options
This 38-minute presentation gives a focused, practical overview of water quality as the main driver of fish health. It explains how to test and interpret core parameters: temperature, pH and buffering, the nitrogen cycle (ammonia, nitrite, nitrate), hardness, salinity/conductivity, dissolved gases, and disinfectants like chlorine, linking each to stress, toxicity, and disease risk, and outlining clear monitoring and husbandry responses for clinical and ornamental settings.
