That's true I guess - probably the water out of the tap was already pretty well treated, so boiling it may not have been necessary. I mainly did it just in case there was any algae in there - I figure it's unlikely that there'll be algae floating around in the air to contaminate it afterwards. I'll have to remember that isopropanol tip - I'd better put some in my next watercooled rig, just to be on the safe side
