Chlorine and pH problems following missing stabilizer

[PoolDoc]

Aquacheck Between 150-200 but closer in color to 150
RP (Pool Store 1) 40 (prior to VP treatment)
VP (Pool Store 2) 150
RP (Pool Store 1) 150 (returned after VP treatment)

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?

Sorry. Trying.

Those are CYA readings:

CYA : Aquacheck => between 150 and 200, color closer to 150; store #1 => 150; store #2 = 140

I will get another sample tested tomorrow as the last printout I have from store #2 was prior to the 10 # of Aqua Prep they had me put in the pool to raise the Ph...which put my TA through the roof. I will post those results after I swing by Store #1 at lunch. I really wish I had known about this site sooner.

TC and FC have not been sustained for more than 8 hours on their own above .5 using OTO kit we purchased.

Got it on the CYA; need the other numbers.

And again:
