No idea what your abbreviations are, nor what the numbers are for.

Please report results in some form like this:

FC (free chlorine): store #1 => x.x; store #2 => y.y; Aquachek => z.z
and so on for
pH
TA (total alkalinity)
CH (calcium hardness)
CYA (cyanuric acid).

And . . . do NOT drain your pool. Draining an in-ground vinyl pool typically destroys the liner!

VP had us put in 10# of granular dichlor chlorine (and check every 4 hours...if FC dropped below 5 ppm add another dose)...keep going until at 5 ppm for 24 hours without treatment. 25lbs sold for $99 and we used almost 3 before we lost hope...did nothing...money gone and CYA now sky high.
Are you saying you've used 3 x 25lb of dichlor?
