CYA in a sock

[polyvue]

However, if you read the instructions on most of the containers of CYA it says to pour it slowly into the skimmer. A few say to predissolve it in warm water and add to the pool but CYA does not really dissolve in warm water (or cold water) very quickly so that just does not work.

I'm pretty sure I don't have "magic" cyanuric acid yet my experience is that when the cya is added to the skimmer it dissolves very quickly (I define "very quickly" as 10 minutes or less). Typically 2 lbs of cya is weighed out and then poured into a gallon or two of warm (90 degree F.) water, stirred up to make a slurry, then poured into the skimmer all at once with the basket in place, 75-100% suction. It's immediately evident in the pump basket but dissipates at the same rate as that in the skimmer.

I find it a bit disconcerting that my experience would seem to contradict the reports of so many others.

NO contriditions. A 'slurry' is not the same as 'dissolved' . It is still getting caught in your filter and slowly dissolving over the next several days.
YOu would see the same if you poured it slowly into the skimmer and allowed it to 'slurry' there.
