Thanks PoolDoc!

Question about the stabilizer though...and forgive the dumb noobie question.

Since my cya (that is stabilizer correct?) is over 120, why do I need to add more? I didn't think draining 12" of water out of the pool would dilute it that much? I was only draining a foot or so out, not everything but a foot.

I was understanding that because my cya was so high i needed to dilute so i could add chlorine that would work instead of getting locked up by the stabilizer?

Should I drain more than 12" out?

I have the k2006 kit on hand now (amazon).

Thanks for the quick response!
