The 2-pack of the liquid will cost about $42 bucks and raise the CYA in a 20K pool by about 37 ppm.

You can buy dry CYA on line in 25 lbs bags for about $45 bucks and it will raise the CYA in the same pool by about 150 ppm.. (Not that you need to use it all at once.. :) )

It lasts forever..

Is this stuff difficult to dissolve? It says pour directly in skimmer, but last time I did that with a CYA product, it clogged my skimmer...and I didn't even pour very much in there.
DO NOT pour directly in the skimmer. I use a skimmer sock, dangle it in front of a return and squeeze it often. I can dissolve 4 lbs or so in under 30 minutes while i'm playing in the pool. Easy once you get the hang of it. I tried an old tube sock the first time and in the dead of winter - didn't think i'd ever get it to dissolve...
