When is superchlorination typically required in pool maintenance?

Superchlorination is typically required after a major algae growth because it serves to significantly elevate the chlorine levels in the pool, which is effective in breaking down and eliminating organic waste, including algae. When algae bloom occurs, not only does it create a cloudy and uninviting pool, but it also consumes chlorine in large amounts, making it less effective for overall sanitation. High levels of chlorine introduced during superchlorination are essential to eradicate the algae and prevent its regrowth, restoring the pool to a safe and clear condition.

In this context, while superchlorination can also be beneficial for clearing cloudy water, eliminating chloramines, or after a rainstorm, it is particularly crucial following major algae growth, as this situation demands a more aggressive treatment approach to ensure that the pool is safe for use.
