I began adding CYA to a new pool yesterday. Put about 2.5 lbs in a stocking and placed in a skimmer. o-ACE-sis brand from Ace Hardware. After 12 hrs, minimal decrease in size of the blob. I took it out and suspended the stocking in front of a return. I've milked the stocking throughout the day today, but still have about 1/3 mass still in the stocking. I see where some have said to pour into the skimmer return. Guess I could do that, and assume it will end up in the filter and eventually be returned in solution to the pool. The directions on the container indicated that one could simply broadcast over the deep end. I anticipate having to add more. Is there a better way, or should I expect 2-3 days' hanging the sock? How do most add?
