My guess is that as long as you mix up a weak batch, you should be OK. Too much bleach may permeate the plastic and give you a chlorine taste for awhile.
When storing emergency drinking water, you can add a couple of drops of bleach to a gallon before you store it.
The fix for left over chlorine taste is a baking soda rinse. I am interested in what others think about this.
