Just finished adding dry acid about 4 hours ago, and have the alkalinity and pH at a good level. I was told to add 1 lb 5 ozs of CYA to pool next, but wasn't told I needed a skimmer. Stuff won't dissolve so I ended up adding just the clear water in and left the chalky stuff in the container. How should I dispose of that? I also just learned from reading posts here that I could put it in an old pantyhose and let it dissolve on its own. Can I still do that even if I have no skimmer. Also, how long must I wait to add shock after the CYA?
