How does the chlorine in pool water affect nearby plants?
I consulted with Dr. Jerry Kidder at the University of Florida about this. I figured that since his state is significantly covered with water (primarily from swimming pools and not from the Everglades!) that he could speak from experience:
There should be no effect of pool water splashed on nearby plants from normal pool use. The form of chlorine most often added to pool water is solid calcium hypochlorite which forms hypochlorous acid (HOCl) when placed in water. Sodium hypochlorite is the active ingredient of common household bleach. Hypochlorous acid is the effective agent that controls algae growths in pools. Larger plants (and animals) can tolerate the concentrations that are recommended for pool water.
