What action should be taken if chlorine levels in the pool are too high?

When chlorine levels in a pool are too high, it's essential to take specific steps to bring them back within safe and suitable limits for swimmer safety and comfort. Adding more chlorine would compound the problem rather than solve it, as the objective is to reduce the concentration of chlorine in the water. Allowing the water to aerate on its own may take a long time and may not effectively reduce chlorine levels sufficiently for immediate use. Increasing pool circulation can help with distribution and may also have a minor effect on reducing chlorine levels, but it won't significantly lower the concentration.

The most effective and immediate action is to dilute the pool water by adding fresh water or using chlorine neutralizers. Fresh water reduces the concentration of chlorine by decreasing the total volume of chlorinated water, while chemical neutralizers specifically break down chlorine, making it inactive. This approach allows for a quicker return to safe swimming conditions, making it the best choice when addressing high chlorine levels.
