Which type of algae requires special treatment to eliminate?

Black algae require special treatment to eliminate due to their unique structure and resistance to typical sanitizers. Unlike other types of algae that can be more readily controlled with conventional treatments, black algae have a protective layer that enables them to attach firmly to surfaces like pool walls and floors. This resilience means that simply shocking the pool with chlorine or using standard algaecides is often ineffective.

Effective treatment for black algae typically involves scrubbing the affected areas to remove as much of the algae as possible, followed by the use of specialized algaecides that target this stubborn variety. Additionally, maintaining proper water chemistry and circulation helps prevent its growth, but addressing an existing infestation requires a more intensive approach. Understanding these treatment requirements is crucial for pool operators to ensure a safe and clean swimming environment.
