The experiment highlights the challenges of controlling algal blooms in natural water bodies. Despite efforts to reduce sunlight exposure, the presence of nutrients from fertilisers remained the primary driver of algal growth. The findings underscore the difficulty of mitigating algal blooms in real-world conditions, where factors like rainfall can disrupt interventions. Algal blooms can harm aquatic ecosystems, reduce water quality, and pose risks to human and animal health, making it crucial to manage nutrient inputs effectively.
