So what have you guys been using? I've been think about iodine when i get mine going. All of the fish tank stuff I've seen is for balancing PH. I couldn't find anything that says "kills bacteria".
Come on now... I know there are more than a few of these out there. Are you all just using water for now. What about a simple in-line filter?
Humidifier anti-bacterial treatment. Look next to filters and such for humidifiers. Takes about 1/4 capful per gallon of water.

There was a thread on this about half a dozen below your post when you first posted it. ("Evaporative water cooling, desinfecting the coolant").
uh... my face is red. All I've seen is aquarium treatments. Thanks for posting, though.
