  1. I use 20 ppm for the protection of copper ans brass in a closed loop, about the same cycled up in a cooling tower.  Tolytriazole is my choice, or a blend of azoles depending upon the system being treated.  Some think 20 ppm is high, but sometimes I use more.  The object is to protect the system, not save on chemical costs.
