Well I'm not sure if this is good practice or not but the guy who started up our pool poured the CYA in the skimmer so that it would be feed into the filter. He said it would disolve the fastest in there. I never tested for CYA so I have no idea how long it actually took to disolve into the water. I'm assuming it would have been fast if it had the volume of water flowing past it through the filter all the time.

Has anyone heard of this as a good way to add CYA?
