Purple or Copper Cyanurate is caused when the Cyanuric Acid (chlorine stabilizer or conditioner) is allowed to become high or over 100 ppm and it then reacts with any copper that may present in the water. Purple Cyanurate is a chemical/mineral imbalance problem. It is NOT an organism or algae problem.
