I took a sample for testing into a local pool store, mainly because they had a coupon in a magazine for 2 lbs. free shock. I expected the hard sell, and was braced for it...."you need this, and this, and gotta have some of this....", but the counter guy says......."you're perfect, every number is in the perfect range......what are you using to chlorinate"....Well, of course.....my answer was liquid chlorine, didn't want to hear the no-no's of using bleach. So, I left with my printout and free shock , a happy man.
