Chlorine smells stronger in indoor pools than in outdoor pools because of the enclosed environment.

In contrast, outdoor pools have more ventilation, allowing the chlorine fumes to disperse more easily, resulting in a less intense smell. Additionally, indoor pools may have higher levels of chlorine to compensate for the lack of natural sunlight, which can help to break down chlorine compounds. **

This odor is due to the chemical reaction of chlorine with organic matter, producing chloramines and other compounds. Both mold and chlorine have distinct and recognizable smells that can be easily identified. **
