Purple Liner and pool

[shelbel]

Has anyone here had a purple pool? You can sweep the power. We've had our pool 7 years and never had this. Pool guy said he's never seen this.

This is most likely copper cyanurate. What is your cyanuric acid level? How much copper is in the water?
Can you provide a full set of chemical readings?
