This type of algae typically presents as a yellowish or brownish substance, often clinging to the walls and floor of swimming pools. It can resemble dirt or sand, easily mistaken for debris settling at the bottom. Its appearance distinguishes it from green algae, which imparts a distinctly green hue to the water.
Accurate identification is vital for effective pool maintenance. Early detection and appropriate treatment prevent its spread and potential issues such as water cloudiness and decreased sanitation efficacy. Addressing this issue promptly preserves the clarity and hygiene of the swimming pool.
