water would be the coolant. Hmm, H2O2. I am not too sure, the peroxide ion is VERY unstable, and will easily break up into H2, H20, and O2, putting air in your system, and wearing itself out over time. I am thinking along the lines of some the anti-algea liquids they use in aquariums to keep algea from growing. HCL would work as it does not eat away copper, but it will react with aluminum and maybe with brass, so it probably wouldn't work. I am going to have to think about it, so far, the anti-algea stuff sounds the best.

Just get some of the anti-bacterial stuff they sell for evaporative humidifiers. It takes like a 1\4 capful per gallon of water. Look in the humidifier section next to replacement belts and such.
not sure why cholrine would be more corrosive than salt though as both would have chlorine ions in them, just the ones with the chlorine tablets would not be as conductive. I think the anti-bacterial stuff sounds good though.
