Someone suggested to me, a while back, that they threw a cup of bleach into the coolant to keep it sterile.

I tried this about a month and a half ago (1 cup into a 35 gal tank) figuring that if it diddn't work I'd just replace it anyway. Seems to work great. No difference in the coolant, it doesn't smell anymore, in fact it looks cleaner than it ever has.

Anyone see any problems with this, Or tried it and had problems?

Well from a chemist point of view:

Chlorine (as in Clorox bleach) + Iron = Ferric Chloride

This is the etchant so many knife makers use. Not to mention that Chlorine and Stainless steel are not a good mix.

Another point about bleach, chlorine will attack the binder in carbide. We just went through a spell of trying to figure out why our tooling we ground was breaking down and wearing out pre-maturaly. Chlorine, chloride and sulphur are 3 big no-no's around carbide. Could cause insert tooling or solid carbide cutters to fail pre-maturally.
