Hi Rick!
Yes, that soil does address the two concerns.
With no watering from the top for over a week the soil's moisture content is just right.
It is the chlorine.
I read about the chlorine in the tap water on another site a while back and forgot about it.
However, the phrasing on that site did not imply certain death if tap water was used.
I do not recall the mention of other minerals on that site and the pamphlet does not mention it either.
It does mention using either rain water or bottled water.
