Yeah its called glycol and it comes in two flavors and colored to
suit. Glycol is not a water treatment and is typically not used in a
residential setting. Try again.

Fer Petes sake. Once the water is added back in to the system it is
purged of corrosive content by the heat. You don't need any additive
whatsoever, unless you are going to leave it inoperative for a long
spell or it is going to be in freezing conditions. It is wise to bleed
the system after a few days, unless you have automatic bleeders. Most
do. Don't let one of them that Union guys near it. They have been known
to urinate into the feedwater. They think it cleans up their drug test. ;-p
