How to Identify and Treat High Free Chlorine Levels in Swimming Pools
High free chlorine levels in swimming pools can be identified by testing the pool water with a chlorine test kit. If the chlorine level is above the recommended range, it is considered high. To treat high free chlorine levels, the pool should be partially drained and refilled with fresh water. Additionally, the pool filter should be backwashed and the pool should be shocked with a non-chlorine shock product. Finally, the pool should be tested again to ensure the chlorine levels are back within the recommended range.
