How fast does alge grow?

Algae can grow at remarkably fast rates, often doubling in biomass within just a few hours under optimal conditions. Factors such as light, temperature, and nutrient availability significantly influence their growth rate. Some species, like certain types of green algae, can proliferate rapidly, leading to blooms that can cover large water bodies in a short time. In contrast, other species may grow more slowly, taking days or weeks to increase their population significantly.
