Monitoring algae health involves regularly observing the color, density, and overall appearance of the culture, as healthy algae should maintain a consistent vibrant color and uniform growth. Regular sampling and microscopic examination can reveal changes in cell shape, size, or behavior, which could indicate stress, contamination, or nutrient imbalances. Measuring water parameters such as pH, temperature, salinity, and dissolved oxygen helps ensure conditions remain within optimal ranges for the chosen species.
Nutrient levels, including nitrogen and phosphorus, should also be tested to confirm they are sufficient but not excessive. Monitoring growth rates through optical density readings or biomass measurements provides insight into how well the culture is performing. Unusual odors, sudden color shifts, or the presence of foam or debris could indicate contamination or environmental stress. Consistent recordkeeping and comparing data over time allows growers to detect early warning signs of problems and make adjustments.
