Yeah, by all means I agree it's the right way to wash new carbon. You are supposed to use RO/DI water but I don't think there are enough impurities in the small amount of water it takes to initially wash it to worry about it. The impurities taken up in tap water are much smaller in size than what we pull out of our tanks.
