I was afraid of that. So that means that if she feels she has to do the chlorine dump approach, then doing the experiment to determine the minimum amount of chlorine that is needed would be a wise thing to do (rather than do shock levels).

I had also thought of the possibility of temporarily switching to Tri-Chlor tabs in a floating feeder, but I don't think they will last for the 10 days and they'll be hard on the pH (though she could start at a higher pH to start).
