Peggy, Have you been using only bleach to chlorinate? It seems from your posts that you are, but I couldn't tell for sure. Some forms of solid chlorine (e.g. trichlor) will lower pH so if you're using that it would explain the pH drop.

At any rate, Dave has you on the right track. Keep up the good work.
