Thanks, Watermom,
I haven't added any CYA yet this year, but have those pucks floating around for whatever they are (or arent') worth.
Should I add the CYA (and how much?)(it seems to be less than 30) before I add tonight's dose of chlorine?
Glad to hear I don't have to worry about the ALK right now. One thing at a time sounds good to me.
I really appreciate the help!
