Water Temp & Dissolved OxygenHydroponics Lab
Calculate max theoretical dissolved oxygen saturation in water reservoirs based on temperature and salinity.
Dissolved salts displace oxygen molecules, resulting in lower saturation capacities at high concentrations.
Hydroponic root health depends on water temperature. Above 22°C (72°F), pythium pathogens thrive while oxygen levels drop. Keep reservoirs aerated and cool.
Warm water drops dissolved oxygen capacity sharply, choking roots and welcoming fungal spores. Aeration pumps must maintain DO above 5.0 mg/L for basic root health.
