What is a necessary step before applying algaecides?

• A. Increasing the pool's water level
• B. Testing and adjusting sanitizer levels
• C. Draining the pool completely
• D. Cleaning only the skimmer

Answer: (B)

Testing and adjusting sanitizer levels is essential before applying algaecides because effective treatment relies on maintaining proper water chemistry. Algae thrive in environments where sanitizer levels are inadequate, so ensuring that the sanitizer—usually chlorine or bromine—is at the appropriate concentration helps increase the effectiveness of the algaecide. When sanitizer levels are too low, adding algaecides may not yield the desired results, as they need to work in conjunction with the existing sanitizing agents to properly eliminate algae. Additionally, testing the water can help identify any other imbalances that may affect water clarity and safety, ensuring a more effective overall treatment plan.
