JJB,
Did you read my post, just beore PD's? Do you think that answers or helps lead to an answer to your long post from last night? I interpret your long post to be asking( in a very detailed way) "Why does my FAS-DPD testing work differently than it seems it should?"

-- OOPS -- so you did.

Take it easy, see if you can clear up the CC in a bucket, then you'll know you can clear your pool.
