Pools can hold various minerals that can affect the composition of the water. There are two types of minerals that primarily cause pools to turn purple – manganese and copper cyanurate. The chlorine added to the swimming pool can oxidize with the metals and cause a noticeable reaction in your pool.
Herein, why is my pool water turning purple?
The purple staining is caused when the pool water has formed something called copper cyanurate. Copper cyanurate occurs when excessive levels of cyanuric acid combine with non-chelated copper that is present in the water. This problem is most common in pools that have cyanuric acid levels measuring above 100ppm.
One may also ask, why did my pool water turn black? The colors may vary from green, red, brown, purple or black.
