The sock full of stabilizer hanging in the return stream worked well. All of the stabilizer in the sock dissolved. Current numbers:

pH=7.5, FC=5.5, CC=0.5, TA=140, CYA=35.

I didn't bother with testing CH (above ground pool with vinyl liner). I'm out of powdered stabilizer, but I have three more Tri Chlor tablets. I plan to use them up to raise the CYA a bit more. I plan to ignore the TA, since I haven't thought of a way to aerate my pool (no fountain or anything like that). The pH has been dropping and I am using borax to keep it at 7.5. The FC has been holding well enough, it dropped from 7.5 last night. We have started swimming - life is good!
