The difference might simply be the amount of ozone in the water. I have yet to see a jug that does not say "ozonated".
Ozone can make your CS come out yellow where, if the same jug is left to vent for a few days and used again...no problem. You'll see bubbles forming on the sides of the jug..or boil it and allow to cool.
