I change water when i change tubes or waterblocks... that's between 6 months and 1 year apart.

Ethylene glycol is chemically similar to alcohol, enough that most bacteria can't live in high concentrations of the stuff. However, I've come across mentions in car-care boards of bacteria that is resistant to the stuff and clogs up the lines for the winshield-washer fluid.
I used water and some Zyrtek (sp?) coolant fluid, which is basically a bunch of salts to prevent galvanic corrosion, and that worked fine for me. Had a little bit of bacteria - slimy, discolored tubes - after six months, but nothing a good rinsing couldn't fix.
