What Causes a Pool to Turn Green?
A pool can turn green due to several factors, primarily related to water chemistry and maintenance issues.
- Algae Growth: Algae thrive in warm water and can quickly multiply if the pool’s chlorine levels are inadequate. This often results from poor sanitation practices or imbalanced pH levels, allowing algae to flourish and turn the water green.
