    Still Learning

    I was wondering why my TA has dropped. Not in a panic here just wanting to learn.

    We had 3.5 inches of much needed rain here yesterday. The below reading are from the day before the rains and today's reading. The SWCG has been off for three weeks and I have been adding Bleach as needed. I drained a few inches from the pool this morning and I always take the reading at night.

    With an accuracy of + or - 10ppm on the test, I would be reluctant to call that a drop. It may well be (from the rain) but my tendency would be to disregard it.
