Same problem here with high CYA that I just discovered with my new K-2006 kit I got last week. And even though I've been lurking around here for four years, the relationship between the CYA and FC totally escaped me because I was told that CYA was not an issue for my indoor pool. (Yup, pool store again.) So now I'll be shocking with bleach and replacing the water for the next week to get rid of it. I have a small utility pump that will do the job. I haven't had any problems with cloudy water but I guess I've been lucky. Indoors and light bather load probably helped.
Why don't they make non-stabilized chlorine tablets btw? You guys provide a great service here. Thank you.
