I've been running straight water for the last two months. Last night I added some alcohol (isopropal) and then this morning a few drops of WW. The reason is I hate WW, so I'm running alcohol as a biocide. Works great. When I popped the top of my radiator I heard a satifing pop sound indicateing that my system is air tight.

Anyway I added a tiny amount of WW. I'm talking 1/10 the recommend amount. The instant it hit the water the stuff turned brillant white. Anyone ever do titrations and add very weak acid to a strong base w/ indicator? It was like that, the red just vanished on contact.

Then the white spread out from the res and within 10 seconds my entire system was white.

Now I've run alcohol and WW before with no trouble. I know thats not the problem. I don't, however, have any idea what happened. Has anyone else seen this before?
