Which of the following is NOT a method of controlling algae?

Using algaecides exclusively is not an effective standalone method for controlling algae. While algaecides can be an important tool in algae management, relying solely on them without implementing other best practices can lead to inadequate control and may even foster resistance in algae populations. Algae thrive in a range of conditions, and a multifaceted approach is essential to prevent and control their growth effectively.

Regular brushing helps dislodge algae from pool surfaces, ensuring that it can be removed by filtration or chemical treatment. Maintaining proper sanitizer levels ensures that the water remains inhospitable to algae growth, as sanitizers kill microorganisms including algae. Enhancing water circulation is vital because stagnant water allows algae to proliferate, while proper circulation helps distribute chemicals evenly and prevents localized growth. Together, these strategies create a balanced approach to algae management that is more sustainable than relying only on chemical solutions.
