Two questions:

1. Are you sure your CH (calcium hardness) is 1,100?

That's 110 drops of reagent! If you haven't already, watch the Taylor videos: http://pool9.net/tk-guide/ and http://pool9.net/tk-interfere/

Also, please test the pH, TA and CH of the water you filled your pool with -- presumably your house water, but upstream of any softener, etc.


2. Can you explain the sequence of the "billowing clouds"? Where were these clouds billowing from?

I don't understand, since vacuuming to waste should have ZERO effect on your pool water, since the discharge water is going out the backwash line.
