Why did my pool turn green when I added chlorine?
Pools can immediately turn green after shocking or adding chlorine when they have metals like copper or iron in the water. These metals oxidize when exposed to high levels of chlorine, which makes the pool water turn green. Metals in the water are caused by some algaecides and using well water.
