Green additve for steam furnace

Bob_105

Two years ago the plumber added two small containers (about an ounce each)of what looked like green and white powder, which made the water in the furnace a light green. It really kept the water clean and the traps were quieter. Can anyone tell me what it is called and where I can get it. Not too many people in my area know about steam, and the plumber is no longer alive. Please help. Thanks

Do you know where I can get it? Would a plumbing supply store have it?

Thanks
