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.

Ordinary dry chemical is for Class B & C fires only.arbon Dioxide fire extinguishers extinguish fire by taking away the oxygen element of the fire triangle and also be removing the heat with a very cold discharge. Carbon dioxide can be used on Class B & C fires.
