What is a common benefit associated with saltwater pools?

A common benefit associated with saltwater pools is that they typically have lower chlorine levels and can result in reduced eye irritation. Saltwater systems generate chlorine through the process of electrolysis, allowing for a more stable and consistent level of chlorine compared to traditional chlorine pools. This method often leads to lower overall chlorine concentration while still maintaining effective sanitation levels.

The result of lower chlorine levels often translates to less harshness in the water, which in turn minimizes the irritation many users experience, particularly in the eyes. This makes swimming in saltwater pools more comfortable for many individuals.

In contrast, higher chloramine levels can be problematic and are usually not a feature of well-maintained saltwater systems. The perception regarding maintenance can also be misleading; saltwater pools generally require less frequent and intensive maintenance once the system is properly set up, as the salt chlorinator automates chlorine production. Additionally, algae growth is often effectively controlled with the stable chlorine levels provided by these systems. Therefore, option B correctly identifies a key advantage of saltwater pools.
